The Allen-Bradley Zero-Force Touch Buttons help to reduce the chances of repetitive motion injuries such as carpal tunnel syndrome. Their sensors detect an operator’s touch, so no pressure is required to activate the switch. The buttons also use self-diagnostic circuitry to provide protection against accidental activation. This circuitry detects faults and hazardous situations such as conductive film deposits, and shuts down the button when they occur. These switches are available for sale individually or packaged in a kit with Nolatron’s 3380 or 4480 series controls.
