ABSTRACT:
A resilient bridge of a snap-action switch is normally held in an unactuated position by virtue of one end portion of the bridge bearing against a lobe formed integrally with a manually actuatable and linearly movable plunger. When the plunger is manually depressed toward an actuated position against the bias of a return spring, the lobe moves away from the end portion of the bridge. As an incident thereto, the bridge changes the state of the switch by automatically snapping over center along a path extending transversely of the path followed by the plunger.
