Abstract
A normally-open switch comprises: a housing; a push button that is mounted for movement with respect to the housing; a stationary terminal; a moveable terminal that, when in contact with the stationary terminal, completes a circuit; and one or more positive stops that engage the stationary terminal. When a force is applied to the push button, the moveable terminal makes contact with the stationary terminal, thus closing the circuit. When the force is removed, the moveable terminal breaks contact with the stationary terminal, thus opening the circuit. The one or more positive stops apply pressure to and maintain a predetermined position of the stationary terminal, but do not interfere with or impede the moveable terminal.
