摘要： Methods and systems for actuating a negative rate switch. A negative rate switch comprising a plunger and a resilient actuator thereof can be provided, wherein a highest plunger force occurs at a free position and a lowest plunger force occurs at a full over travel position. The negative rate switch can be configured such that when the resilient actuator provides resilient actuating force to overcome a free position force associated with the free position, the plunger moves without interruption through a total range of travel thereof and when the resilient actuating force drops slightly below a full over-travel plunger force associated with the full over travel position, the negative rate switch overcomes the resilient actuating force to return the plunger to the free position thereof without interruption.

摘要： A nonrecycling reset switch has a fixed position anchor mounted on bosses in the casing for holding a resilient member of the conductive snap spring which moves between open and closed positions. A leaf spring or other resilient member is anchored adjacent the snap spring to control the force of snap over when the switch opens or is reset to the closed position.

摘要： A constant load and constant contact force snap-action switch having a normally-closed movable operate contact on a flipper blade which has a compression strip that snaps through an S-curvature to a reverse buckled state to trip the operate contact open. The flipper blade is coupled through an insulating cap to the leaf spring mounted movable alarm contact to close the latter at the same time. A return spring biased reset lever resets the operate contacts on depression down a first amount, opens the operate contact without closing the alarm contacts on depression down a second amount for stop purposes, and trips the operate contacts open on lifting upwards for test purposes. On reset, lost motion in the coupling cap knocks the alarm contact open if welded. A selector is settable to select any of three functions for the reset lever, (1) reset-stop-test, (2) auto reset stop, or (3) reset test.

摘要： An electrical switch, comprises a housing having spaced apart side walls each with a bearing recess which is located above spaced apart fixed contacts. An actuator is guided in the housing between the side walls and moves toward the fixed contacts to move first leg portions of substantially U-shape contact springs to flex these leg portions and pivot intermediate web portions which are pivotal in the bearing recesses and, thereafter, snap second leg portions into engagement with the fixed contacts. The arrangement may include two sets of spaced apart contact members between which the second leg portions of the leaf springs are movable and the first leg portions are preferably pivotally connected between depending feet of the actuating member. The second leg portions include curved recesses located below the feet which are similarly curved so that the feet engage into the recesses and move these leg portions before the second leg portions are snapped into a contact engagement with one or the other of the fixed contact members.

摘要： A switch assembly includes an M-blade snap spring, an actuation arm, and a switch. The M-blade snap spring exhibits snap-action movement between a first actuator position and a second actuator position. The switch is responsive to the snap-action movement of the M-blade to move between a first switch position and a second switch position. The actuation arm is configured to selectively cause the M-blade snap spring to move, via snap-action, between the first actuator position and the second actuator position, which in turn causes the switch to move between the first switch position and the second switch position, respectively.
