| A method of adjusting an electrical switch arrangement comprising a pair of electrical contact members to a predetermined contact spacing is suggested. A first one of the contact members is associated with a first contact carrier and a second one of the contact members is associated with a second contact carrier. The first and second contact members are normally spaced from each other by the predetermined contact distance and are movable relative to each other across the contact distance. At least one of the contact members is displaceably held on the associated contact carrier. The contact carriers are moved towards each other across the predetermined contact distance. The one of the contact members is displaced relative to the associated contact carrier into physical contact with the other of the contact members. The one contact member is fixed in position on the associated contact member while physically contacting the other of the contact members. | ||||||
| 76 | Method for thermally calibrating circuit breaker trip mechanism and associated trip mechanism | US940475 | 1997-09-30 | US6030114A | 2000-02-29 | Bernard DiMarco; Robert G. Bergman; David A. Leone; Christoph Hamann |
| A method for adjusting the calibration of a circuit breaker trip mechanism including a terminal element, a bimetal element connected thereto, and a trip bar. Laser energy is applied to lanced or pre-bent surfaces of the terminal element to thermally induce displacement thereof and thereby modify a trip distance between the bimetal element and the trip bar. Where a laser beam is directed to fall on a middle leg of a lanced or pre-bent section of the terminal element, the bimetal element moves in one direction relative to the trip bar. Conversely, where a laser beam is directed to fall on lateral legs of the lanced or pre-bent section of the terminal element, the bimetal element moves in an opposite direction relative to the trip bar. Thus, laser energy may be applied from the same direction, or to the same side of the trip structure, regardless of whether the trip time is to be increased or decreased. | ||||||
| 77 | Low cost thermostat apparatus and method for calibrating same | US9609 | 1998-01-20 | US5986535A | 1999-11-16 | Jan J. Stiekel |
| A low cost thermostatic switch (10) has first and second scoop shaped terminal members (12, 14) having flanges (12e, 14e) received on ledges (20f) formed on opposed sidewalls (20e) of a housing (20). The terminal members are spaced apart with the distal end portions (20g) of the sidewalls of the housing bent over to clamp the terminal members to the housing with a strip (16) of electrical insulation placed therebetween. A movable contact arm (22, 22', 22") is cantilever mounted on the bottom wall (14a) of one terminal member (14) movable into and out of electrical engagement with a stationary contact (26) mounted on the bottom wall (12a) of the other terminal member. A motion transfer pin member (28) is adjustably mounted on the movable contact arm and extends downwardly toward a thermostatic snap-acting disc (30) received on a disc seat (20b) formed on the bottom wall (20a) of the housing with the disc adapted to transfer motion through the motion transfer pin member (28) to move the movable contact arm out of electrical engagement with the stationary contact (26) in one of the two oppositely dished configurations of the disc. A spring 32 is mounted in the housing (20) in a modified thermostatic switch (10') to maintain snap-acting disc on the disc seat (20b) regardless of the orientation of the switch. The switch is calibrated by adjusting the position of the motion transfer pin relative to a reference level to be within a selected gap and then deforming the sidewalls of the housing until the movable contact moves out of electrical engagement with the stationary contact (26). | ||||||

| In known electrically operated handheld machine tools, a potentiometer serving to control output must be balanced so that a desired tap resistance can be tapped at the potentiometer in a determined adjustment position of the potentiometer. To reduce manufacturing expenses, this balancing is effected without required additional structural component parts or costly additional devices.The potentiometer (20) has a resistance path (21) with which a slider (22) is in electrically conducting contact by pressing. The slider (22) can be actuated manually by an actuating member (15). The slider (22) and actuating member (15) have means (26) for adjusting their relative position with respect to one another after their insertion into a housing (11) of the handheld machine tool. | ||||||
