CONTACT MOVED BY SUDDEN RELEASE OF STORED ENERGY (E.G.,SPRING CHARGER):
(under the class definition) Subject matter wherein the switch device includes (a) means to stress a spring device, (b) a latching device for holding the stressed spring from operating after being stressed, and (c) an actuating device to release the stored energy of the spring to open or close a circuit.
(1) Note. Often the spring or stored energy device is charged by an electric motor.
(2) Note. These switches differ from snap switches in that snap switches have an actuator (e.g., a lever, rocker, push button, knob, etc.) which charges a spring and then during its motion releases the spring.
