| The invention relates to an electric switch (1) with a contact system (9) which consists of at least one fixed contact (10, 11) and of a movable contact tongue (12). A movable actuating member (5) is operatively connected to the contact tongue (12) for changing over the contact system (9). The contact tongue (12) is arranged on a bearing (18) designed in the manner of a knife-edge bearing. The switch point of the contact system (9) is adjustable by the shift of part of the contact system (9) in the direction of movement (20, 20′) of the actuating member (5), in that the bearing (18) and/or the fixed contact (10, 11) and/or the contact tongue (12) is capable of being set in the direction of movement (20, 20′) of the actuating member (5). In order to adjust the switch point of the contact system (9), part of the actuating member (5) may also be capable of being set in the direction of movement (20, 20′) of said actuating member (5). | ||||||

| 26 | Two pole circuit breaker calibrated in assembled state | US09649364 | 2000-08-28 | US06239676B1 | 2001-05-29 | James Gerard Maloney; Miguel Angel Gonzales; Ronald Dale Smiddle |
| A two-pole miniature circuit breaker is configured for calibration of both pole mechanisms with the circuit breaker fully assembled. The identical pole mechanisms are mounted in the same orientation in parallel outer compartments of a molded housing with the metal support frame of one pole against the outer housing wall and the frame of the other spaced from the associated outer wall. A coupler couples the two-pole mechanisms together for simultaneous opening of both poles when either pole is tripped has an actuating member on each end which engages the trip device of the associated pole. The actuating member, at least of the pole with the metal frame spaced from the housing outer wall, is configured to provide direct access for a calibration tool inserted through a calibration opening in the housing to engage a calibration slot in the metal frame. | ||||||

| A support plate for a circuit breaker has a longitudinal slot centrally located in the support plate, a free end with a tab for affixing an elongated bimetal of a trip assembly, a longitudinal edge opposite to the free end and terminating in proximity to a latch ledge of a cradle of an operating mechanism, opposed lobes each having a transverse edge, and an opening in each of the transverse edges. The support plate extends partially along a planar wall of a base of a housing for the circuit breaker. Molded pins in the base of the housing of the circuit breaker enter the openings in the transverse edges of the support plate for securing the support plate to the base. These molded pins extend outwardly to space the support plate away from the cradle of the operating mechanism. Bent over tabs are provided in one of the lobes for abutting a cover of the circuit breaker to maintain the fixed position of the support plate in the housing base. | ||||||

| 30 | Condition-responsive snap-acting member, device and method of making | US631554 | 1990-12-21 | US5092124A | 1992-03-03 | Sheldon S. White; Lawrence E. Cooper; Rene N. Langlais |
| A movable condition-responsive member such as a snap-acting dished metal member is mounted in a condition-responsive device to move between spaced dispositions such as between the original and inverted dished configurations of a dished metal member in response to occurrence of selected pressure, force or temperature conditions. The member is arranged to engage and move the device control elements during such movement to perform control functions. A series of artifacts such as laser-melted portions of the metal materials embodied in the member are provided in the surface of the member, typically after the member is assembled in the control device. Each artifact establishes a local pattern of stresses in the member at variance with a pattern of stresses in the member adjacent to the artifacts, and the artifacts cooperate to precisely determine the condition which results in the snap-acting member movement. The member is intially formed and processed in conventional manner to provide the member with intended initial condition-response properties differing by selected value from the properties ultimately to be established in the member, and is tested to display its actual properties as initially formed. The artifacts are each proportioned to modify the condition-response properties by only a small increment of said value and they are formed in sequence, typically after member assembly in the device, as the response of the device is tested to precisely determine the condition-response properties of the member in the device. | ||||||

| PROBLEM TO BE SOLVED: To provide an electromagnetic relay capable of easily adjusting operation characteristics.SOLUTION: The electromagnetic relay includes: an electromagnet 1; an armature 2 rotatable with respect to the electromagnet being driven by a magnetic force of the electromagnet 1; a card 8 that moves linearly being pressed by the armature 2; a movable contact 51 interlocked with the card 8; and a fixed contact 52 to/from which the movable contact 51 comes into contact/separates away by the rotation of the armature 2. The armature 2 includes: two armature elements 21 each of which is a flat magnetic body; and a connecting piece 24 which is a plate made of a plastically deformable material and the thickness of which is smaller than the thickness of the armature element 21, is positioned between the armature element 21 and the card 8 with the thickness direction of which oriented in a rotation direction of the armature 2. The characteristics of the armature element 21 can be adjusted by plastically deforming the connecting piece 24, which is easily deformable due to the thickness smaller than that of the armature element 21. Compared to the case where the armature element 21 directly comes into contact with the card 8, the characteristics of the armature element 21 can be easily adjusted. | ||||||

| PROBLEM TO BE SOLVED: To provide method and apparatus of manufacturing a relay that enabled to adjust an electric property of the relay by regulating bending of a contact spring member using plastic processing without contact and that enables such an adjustment in a micro-relay. SOLUTION: A laser 1 is irradiated to a contact spring member 2 in the optimized laser energy condition, and as it generates temperature differences between a front surface and a rear surface of the contact spring member 2 in laser irradiation position and then plastic deformation is performed toward the side of lower temperature at these temperature differences, it can adjust the electric property of the relay by adjusting the bending of the contact spring member 2. | ||||||
