Abstract: A switch includes a spring. The switch further includes a collapsing element. The spring has a first state in which it is being held in tension by a restraining element and a second state in which it is not being held in tension because the restraining element has failed. The collapsing element is situated such that when sufficient power is applied to the collapsing element heat from the collapsing element will cause the restraining element to fail. The switch further includes a first contact coupled to the spring. The switch further includes a second contact coupled to the spring. The first contact and the second contact are separate from each other when the spring is in the first state. The first contact and the second contact are electrically connected to each other when the spring is in the second state.

Abstract: A closed loop feedback system controls electrical switchgear that moves at least one contact relative to another contact to switch power on and off in an AC electrical circuit. The control system includes a position feedback device that is operatively coupled to at least one of the two contacts to produce contact position information. A processor receives and analyzes the contact position information to control contact motion to provide AC waveform synchronized switching. The electrical switchgear may be a capacitor switch that includes a bi-stable over-toggle latching device. The latching device maintains the contacts in one of an open stable position in which electrical current does not flow through the contacts or a closed stable position in which electrical current flows through the contacts.

Abstract: A snap acting switch comprising an elongate cantilever mounted spring member having a contact portion, an electrically conductive element upon which the contact portion bears, and an actuator having surfaces intersecting at an angle, one of the surfaces bearing on the spring member. The switch is actuated by causing the spring member to approach and pass over the intersection of the surfaces, which causes the bearing pressure of the contact portion to increase before the snap action occurs.

Abstract: A snap acting electrical switch in which a frame carries first, second and third wireform contacts and a plunger movable along a first axis. The first and second wireform contacts are biased together along a second axis transverse to the first axis, and are also biased against an end of the plunger. The first and second wireform contacts together are adapted to be deflected along the second axis by a cam surface on the housing as the plunger is depressed. As the second contact is caused to slide off the end of the plunger, it snaps against the third wireform contact which is in a fixed position along side the plunger.
