  • Patent number: 4408250
    Abstract: A system for controlling an electrical load having a magnetic latching relay operable in response to a change in the direction of current through said relay. A control circuit is provided having a switch with one contact connected to a contact of the relay. A first current path and second current path are supplied to a second contact of the switch. The current paths are enabled when the switch operating member connects the relay to the second contact. One of two current carrying paths are provided between the second contact and a source of electrical voltage. The current paths are enabled in response to the voltage stored on a capacitor connected to the first of said contacts. Depending upon the state of the relay, the proper current path is enabled, permitting a change in state of the relay.
