Blickman 3628 Door Switch Complete Assembly

The Blickman 3628 Door Switch Complete Assembly detects the position of the door and turn on or off electrical circuits when the door is opened or closed on a compatible commercial system. Internal contacts are mechanical contacts that sense the movement of the door and send a signal to the connected control modules for operational switching depending on the door state and triggering circuit, connecting or disconnecting when the door is open or closed. Typically located at enclosure access points where door actuation control is required, in equipment assemblies, usually in conjunction with access panels or hinged door frames, for circuit secure interlocking for the controlled operation layer.
