| 101 | Manually actuatable integrated control module and method of making same | US282839 | 1994-07-29 | US5525846A | 1996-06-11 | Edwin R. Newell; Michael B. Carter; Jackie C. Sullivan |
| A manually actuatable integrated contact module connecting to an output access module by means of a common communications link. The integrated contact module has an electrical contact, a logic circuit, a communications circuit and a communications terminal mounted on a common printed circuit board. The printed circuit board provides communication between the electrical contact and the logic circuit, between the logic circuit and the communications circuit, and between the communications circuit and the communications terminal. The printed circuit board is enclosed within a protective housing. A contact operator is slidably mounted with respect to the printed circuit board such that it is partially enclosed within the housing and movable between a first position and a second position. An operator interface device in mounted on one side of a control panel and the integrated contact module is attached to the operator interface device an the opposite side of the control panel such that the operator interface device is in communication with that portion of the contact operator outside the protective housing. The contact operator, in response to movement of the operator interface device, causes the contact to change state thereby initiating a signal to be processed by the logic circuit and communications circuit prior to being placed on the common communications link. | ||||||
| 102 | Keyboard switch | US495898 | 1990-03-19 | US5057807A | 1991-10-15 | James M. Longly; David G. Knapp |
| The switch comprises a square, hollow housing. A base plate and a cover plate are snap fitted in stacked relationship. First and second elongated cavities in the base plate are respectively aligned with first and second cavities in the cover plate and within these aligned cavities are respectively located two elongated reed switches. A plunger is slidably carried by the housing and movable toward and away from the plates. The plunger carries two pairs of magnets respectively aligned with the reed switches. When the plunger is depressed, the magnets move into close proximity with the reed switches, closing them. A spring biases the plunger away from the reed switches, whereby the reed switches are normally open. | ||||||

A battery powered illuminating device is mounted in the vicinity of the breaker and the illuminating circuit is interrupted by a magnetically actuated switch that is closed when a permanent magnet mounted on the switch lever comes within a predetermined distance. The position of the magnetic switch is selected so that it is actuated or closed when the switch lever is in the overload position. | ||||||
| 104 | Bounce dampening system for switch actuators | US753326 | 1976-12-22 | US4264225A | 1981-04-28 | John N. Cassell; John A. Elder, Jr.; Benjamin G. Pastrick; William J. Thornhill |
| A bounce dampening system reduces switch actuator bounce when the actuators are restored to their home position. Included are selection interposers, one of which is selectively driven to thereby effect motion of selection bails and corresponding switch actuators. A reverse interposer is simultaneously driven. A spring restores the reverse interposer after the actuation cycle thereby carrying the bails and switch actuators to their home position. The return spring and the mass of the reverse interposer prevents actuator bounce and insures a timely return of the actuators. | ||||||
| 105 | Keyboard switch | US777401 | 1977-03-14 | US4117430A | 1978-09-26 | Dewey M. Sims, Jr. |
| A keyboard switch is actuated by the depression of a magnetized plunger into the region of a magnetic sensing device positioned at the lower extreme of plunger travel. The plunger is integrally formed of a plastic, magnetizable material and has a central, longitudinal opening that receives and registers with the sensor. The change in magnetic field intensity associated with plunger travel is detected by the sensor and translated into a signal representative of switch actuation. | ||||||
| 106 | Cartridge for magnetically operated contacts | US610121 | 1975-09-04 | US4015226A | 1977-03-29 | Thaddeus Stomma; Edwin J. Wroblewski |
| A pushbutton switch is described in which a pair of contact cartridges containing magnetically operated sealed switches are mounted to an actuator section. The linear motion of the pushbutton is converted to rotary motion by a cam structure mounted in each cartridge and a magnet mounted therein between two switches is thus rotated about a switch axis. By properly polarizing the magnet and by using a magnetic shield, the switches are made to operate as the magnet is rotated to provide a number of possible modes of operation. | ||||||

| This disclosure relates to a push-button switch comprising a housing provided with a support means for supporting a magnetic member, a reed switch element fixedly and vertically positioned in the housing, a lower spring contained in the housing, a magnet mounted on the lower spring which is capable of moving up and down with respect to the reed switch while its upward movement is restrained by the support means and also said magnet is capable of being attracted to the magnetic member in the ordinary state, a pusher capable of moving up and down, a first upper spring applied to the pusher member at its one end, and mounted on the magnet at its other end and a second upper spring also mounted on the magnet and vertically distant from the pusher at a first pushed down displacement of the pusher whereby, before a state in which the pushed down force applied to the pusher overcomes the critical resistance of the sum of the initial resilient force of the lower spring and the magnetic attractive force acting between the support means and the magnet, whereby the magnet carried out the downward snap action thus forming a magnetic field which operates the reed switch, firstly the pusher undergoes the first pushed down displacement while being opposed by the resistance from the first upper spring so that the pushing down force on the pusher equals the force of the sum of the resilient force of the first upper spring and the initial resilient force, and then, the pusher is further pushed to a critical displacement where the pushed down force overcomes the above-mentioned critical resistance force.

| 112 | Alternate action mechanism | US3691333D | 1971-03-19 | US3691333A | 1972-09-12 | ELLIOTT PHILLIP M |
| The present invention relates to a new improved alternate action mechanism for control devices, such as switches, which utilizes a pawl mounted for free rotation on an actuator and for operative association with camming surfaces formed in an associated hollow casing. The camming surfaces act to partially rotate the pawl on an initial downward stroke of the actuator to such an extent that the pawl cooperates with the camming surfaces to preclude total return of the actuator without subsequent reciprocal motion of the actuator further rotating the pawl. Contiguous opposite sides of a pawl tooth are engaged by a shoulder portion of said camming surfaces to prevent return.

| A reed switch includes a housing with a pair of magneticallyresponsive contacts mounted therein, which contacts are closed when an axially-movable magnetic actuator reaches a specified distance with respect to the contacts. A plunger is carried by the housing and moves the actuator toward and away from the contacts. Adjusting means are provided which operatively engage the magnet and the plunger for varying the initial distance of the magnet from the contacts. A cap is removably attached to the plunger and is constructed to conceal and protect the adjusting means.

| 114 | Mechanically actuated electric switch assembly | US3681724D | 1971-07-01 | US3681724A | 1972-08-01 | SHEPARD JOSEPH EMANUEL |
| A highly reliable and readily serviceable electric switch is afforded by a simple and inexpensive magnetic reed switch capsule and a pair of tubular magnets slidably arranged over the capsule. Like magnetic poles on the annular faces adjacent each other hold the magnets apart until they are brought together by mechanical switch actuating means. When brought together by the actuating means, the change in the magnetic field about the reeds actuates the magnetic reed switch contact elements. A minimum of mechanical wear is encountered, and the magnetic reed switch capsules are quickly and conveniently replaceable. A plurality of such magnetic reed capsules may be actuated by a single pair of tubular magnets. All of the reed switch elements may be activated substantially simultaneously or the capsules may be offset with respect to one another for actuating the various reed contact elements sequentially. Push button arrangements are described for keyboard applications.

| At least one glass tube enclosed magnetic reed switch is mounted on a planar printed circuit board which is removably inserted into a hollow housing member in grooves on either side of an axially movable planar key member with a magnet thereon actuating the switch contacts during a limited range of movement. This provides a universal mounting arrangement wherein one to four switches and other circuit elements may be located upon the printed circuit cards for operation by a single manually depressed key at one or more positions of its stroke. Each switch is standardized for predetermined operation timing during the magnet movement by selectively bending the leads and inserting into registration apertures in the printed circuit boards. The switch is thus precisely located within the magnetic field by simplified structure affording strain relief at closed ends of the glass tubes. The leads are bent normal to the reed switch axis for this purpose at calibrated positions to thereby precisely locate the magnetic switch gaps by means of punched hole pairs easily located to close tolerances in the printed circuit board.

| 117 | Magnetically operable momentary switch assembly | US3656181D | 1970-10-20 | US3656181A | 1972-04-11 | PACK HOWARD S |
| A magnetic flux field momentarily produces a first reed switch mode upon movement of a permanent magnet to a selected position and aspect in response to depression of a self-restoring manual member. Thereafter, during the depressing stroke, a spring which had been tensioned in response to depression of the manual member is released from a restraint. The untensioning force snaps the magnet to another aspect to effect a second reed switch mode. Cam means comprising the spring restraint also enables return of the permanent magnet from its end stroke position to its start stroke position without change of aspect, whereby the second mode of the reed switch is maintained.

| Pushbutton switches of the type in which, in each bank, the depression of one button releases a previously depressed button. A printed circuit board leading to the electrical contacts of one bank of switches acts also as a sidewall for that bank of switches, and an electric and magnetic field shield member serves as its other sidewall. Additional features of these switches include simple and inexpensive one-piece plungers, simple means for automatically illuminating the depressed buttons, means for automatically electrically indicating whether a pushbutton in a bank is depressed, and means for resetting, in unison, a plurality of banks of switches.
