Optical touch buttons from Turck. This optical touch button does not require physical pressure for actuation and is designed to replace mechanical push buttons as well as capacitive touch switches. The optical touch button is activated as soon as a finger enters the "touch area" of the switch and interrupts the infrared scanning beam of the button. There are no strains on the hand, wrist, or arm as with mechanical push buttons. The LED indicator lights up when the output relay is activated.
