MICRO SWITCH AC Series switch assembly monitors the position of a service door or panel whether closed or open. The AC Series switches are a compact switch assembly designed for equipment applications. When the equipment (door or panel, etc.) which is electrically interlocked through the AC Series switch is opened, the action of the AC Series switch disconnects the electrical power. The AC Series switch can provide an electrical signal to an annunciator circuit such as a light or horn indicating the door or panel is open. AC Series switch assemblies are available with up to four switch elements which can provide discrete outputs as required for control and/or indicator circuits.
