ABSTRACT:
An electrical switch includes a movable contactor which is actuated by a push button to engage a movable contact with a normally-open contact. A spring yieldably resists depression of the push button and normally maintains a clearance between the push button and the contactor. The spring is superimposed relative to the connector and engages the latter to act as a heat conducting fin. A free end of the spring slides in a notch of the push button. In one embodiment, the spring produces a varying rate of resistance to depression of the button. In another embodiment, the spring urges the connector to its normal position in response to release of the button.
