    Abstract: A switch assembly comprises a plurality of contacts, a switch including a contact bridge and an armature connected to the contact bridge, and a switch status detector positioned remotely and electrically isolated from the switch. The switch has an open position in which the contacts are electrically separated from one another and a closed position in which the contacts are in electrical contact with each other through the contact bridge. The switch status detector includes an electronic oscillator coupled with a coil wrapped around a core. The switch status detector outputs an oscillating voltage that varies depending upon a position of the switch between the open position and the closed position.
