Zero-Force Touch Buttons 4487 Low Voltage Detector – IfThe Allen Bradley Zero Force Touch Buttons help to reduce the chances of repetitive motion injuries such as carpal tunnel syndrome. Their sensors detect an operators 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.
