The DUO-TOUCH® Run Bar with STB Self-Checking Optical Touch Buttons is designed to satisfy the ergonomic principles found in ANSI B11.TR1 to reduce the hand, wrist, and arm stresses associated with mechanical push buttons. The rugged 13-ga. steel housing is designed to prevent inadvertent switch actuation due to objects (such as loose clothing or debris) which might accidentally block the sensing beam.
The STB Touch Buttons are touch-activated photoelectric devices designed to replace capacitive touch switches and mechanical push buttons. Their outputs activate when a
finger is present in the yoke (“touch area”) of the switch, interrupting the button’s infrared sensing beam. These “buttons” require absolutely no physical pressure to operate, and are immune to EMI, RFI, and ambient light interference
