A plunger switch has an actuator that makes or breaks the circuit contact when its button is depressed. A momentary switch, sometimes called a spring return switch, automatically returns to the rest position. A normally ON switch (also called a normally closed circuit), remains in the ON rest position until pressure is applied to the actuator. Single pole, single throw (SPST) is a two terminal switch that opens or closes one circuit.

This round momentary plunger switch is commonly used for refrigerator applications.

Features tab terminals for an easy, quick connection.
