The HUSD-15B Series is a Form C (SPDT), dual button hold-up switch that is designed to generate an alarm condition only when both buttons are pressed simultaneously, thus preventing accidental triggering. The housing of this series is specially designed with a status window, red (alarm) and blue (armed), to verify the switch condition. The housing mounting screw is concealed to provide additional tampering protection. The built-in UL approved micro switch design generates an alarm condition when the cover is removed or damaged. The terminal strip consists of three wire ports that provide a firm and secure wiring installation. The HUSD-15BL is designed for latching operation when triggered.
