Abstract
An electro-static discharge shield on the external non-finger contact surface of a switch makes a contact between the shield itself and the grounded chassis. Since the shield has substantially lower resistance than the surface or inner circuitry of the switch, external electro-static discharge introduced on the surface of the switch flows through the shield to ground via the grounded chassis to prevent destruction or interruption of the circuit.
