| 161 | Manually portable start control for electrically powered apparatus | US386940 | 1982-06-10 | US4442327A | 1984-04-10 | Frank L. West; Larry A. Norton |
| Electrically powered apparatus is provided with a remote primary control station from which energization of the apparatus is usually controlled, and a secondary control station, such as a jog control station, which is remote from the primary control station and close to the apparatus, from which energization of the apparatus may also be controlled. A single manual push button start control module may be mounted at either station, so that when the module is at the secondary station there is no start button at the primary station. A holding circuit provides for extended energization of the apparatus when the push button is momentarily depressed at the primary station, and there is a stop button at the primary station; while the secondary station has no holding circuit. The holding circuit is disabled when the module is mounted at the secondary station, so the apparatus cannot be energized by mounting a second identical start control module at the primary station. | ||||||
| 162 | Pivoted actuator off lock switch with operator key nonremovable in ON position | US410103 | 1982-08-20 | US4440994A | 1984-04-03 | Gursharan P. S. Nat |
| An operator (10) having a lock releasing key (10a) formed thereon is removably coupled to a pivoted actuator (6) by resilient tabs (10d) depending from the operator which are cammed outwardly over the actuator during coupling operation and which engage with undercut surfaces (6e) in the actuator when the operator is fully seated upon the actuator. The tabs (10d) seated at one end of the actuator align with formations (4e) in the housing (2, 4) in the ON position of the actuator to prevent outward camming movement of the respective tabs, thereby preventing removal of the operator in the ON position. | ||||||
| 163 | Miniature lighted pivoted actuator switch with integral lock | US245429 | 1981-03-19 | US4345121A | 1982-08-17 | Richard B. Tenner |
| A miniature toggle switch having an actuator (20) pivotally mounted in a base (2) for operating contacts (8, 10, 12, 16). A switch lock is provided by a one-piece leaf spring (34) press-in mounted at one end in a slot (20f) in a side ledge of the actuator so that its other end abuts a shoulder (2g) in the base to lock the switch in one position. This lock spring is provided with a knee bend (34c) that sticks out beyond and below the actuator ledge (20d) in which it is mounted. A removable operating lever (26) has a pair of hooks (26a, 26b) for snap-on mounting it on the side ledges of the actuator. One of these hooks engages the knee bend (34c) of the lock spring to bias it clear of the shoulder (2g) to allow normal switch operation. A lamp (28) is mounted in the bottom of the base and extends up through a hole (20c) in the actuator to light the operating lever (26) as an indication. | ||||||
| 164 | Removable push-to-unlock actuator for locking pivoted-subactuator self-enclosed electric switch | US111149 | 1980-01-11 | US4291207A | 1981-09-22 | William L. Reinke; John W. Stearley |
| A unitary, self-enclosed electric switch having a pivotally mounted subactuator (6) that actuates the contacts (18 ) and carries a locking element (24) that normally catches on the switch housing (4k) to lock the switch in "off" position. A combined actuator and lock release member (8) is snap-in mounted on the subactuator and has push-to-unlock means (8b, 8c, 22) that releases the off-lock to allow pivotal actuation of this actuator and the subactuator in unison from "off" to "on" position. This actuator is normally spring-biased (22) into ineffective position from which it must be pushed in to unlock the switch and is removable to prevent unauthorized use of the switch. The subactuator has an upward extension (6h) that serves as a handle to enable the switch to be moved from "on" to "off" position even when the actuator has been removed, this extension serving also to trap the actuator bias spring (22) to retain it in place when the actuator is removed. The off-lock shown could be changed to an on-lock by rearranging the contacts or reversing the locking element. | ||||||

| A programmable switch in the form of an output display similar to those generally known in the art as a seven-segment display used for digital display of output. This programmable switch provides a plurality of segments that can operate as a switch to generate a numerical or alphabetical program for entry into an electronic program circuit. The plurality of segments are recessed into the face of the switch body so that a stylus instrument can be inserted into the recess of individual segments to generate in each switch body the desired number, letter or other symbol. A plurality of switch bodies may be positioned adjacent one another to increase the number of digits or indicia to be entered into an electronic program circuit. For all segments there is one conductive layer which acts as the "common" side of the electric circuit. Beneath the conductive layer is a segmented printed circuit which is contacted by the "common" side conductive layer when a stylus instrument is inserted into a recess of a switch segment. One common can serve all the switch segments. One version has an open-cell foam layer between the "common" conductive layer and the printed circuit board for electrical isolation between the common and printed circuit prior to actuation of a switch by insertion of the stylus into the segment. | ||||||
