The OTBVR81 is a Momentary Action Optical Touch Button are touch-activated photoelectric switches designed to replace capacitive touch switches and mechanical push buttons. The OPTO-TOUCH's SPDT electromechanical relay or solid-state output (depending upon model) is activated for as long as a finger, introduced into the "touch area" (yoke) of the switch, interrupts the OPTO-TOUCH's infrared sensing beam. Two indicator LEDs. One lights whenever power is "ON", the other lights whenever the output relay is activated.
