    Product Details

    Honeywell Button Microswitch, NO/NC, 15A - BZ Series - BZ-2RD-A2

    Use this Honeywell microswitch to detect a mechanical target and close or open a connected circuit. As a microswitch, the unit is much smaller than a standard limit switch, making it easy to install in cramped or narrow work areas that would normally be inaccessible. It’s designed for low currents of 15A or less at 125V of alternating current (AC). The button-type actuator in this component is pushed down when in full contact with the target for effective operation.
