ABSTRACT:
An electrical switching device having an actuator reciprocable between two extreme positions, the switch being open and closed, respectively, when the actuator is in its two extreme positions. An electrical operator, such as a solenoid having a movable armature, responds to successive momentary energizations by moving the actuator first to one extreme position and then the other. The actuator is mechanically held in each extreme position by a spring-biased element which also serves to transmit movement of the actuator to the switch contacts. The actuator may have a cam surface shaped to cause opening and closing of the switch contacts, the cam surface also cooperating with the spring-biased element for urging the actuator toward each of its extreme positions. The switching device may be used for interrupting electric power to a customer of a utility by being located between a watt-hour meter and the customer's load, or in other similar applications.
