This IR wireless footswitch eliminates the nuisance of wires under foot while invisible infrared light waves fill the room with 360 degrees of signal. Also, because it uses light rather than radio waves, it resists interference. The twin channel foot switch is available with up to five functions (single version also available). The battery life of the unit is 200 hours at a 50% duty cycle (3 AA batteries). The transmitter is IP68 rated.
