  • Publication number: 20060022780
    Abstract: A magnetic latching switch. The switch includes a pair of switch terminals, a switch actuator, an electromagnet and a biasing member. The switch actuator is manually moveable from a first position where the switch terminals are in a first state to a second position where the switch terminals are in a second state. The electromagnet selectively applies a magnetic field. Applying the magnetic field with the electromagnet when the switch actuator is in the second position maintains the switch actuator in the second position. The biasing member is coupled to the switch actuator such that the biasing member automatically returns the switch actuator from the second position to the first position when the magnetic field is removed.
