The circuit recloser is shown to include the bistable magnetic actuator, a contact switch, a connecting member, connected between the actuator the contact switch and a spring, connected to bias the connecting member in relation to the contact switch. When the actuator is in its second position the end of the connecting member is spaced from the end of the contact switch, i.e., over travel is present. An indicator is provided for indicating whether the contact switch is open or closed.
