ABSTRACT:
A digital switch assembly which comprises a casing having a plurality of output terminals, a rotor rotatably accommodated within the casing and adapted to be rotated either directly or indirectly by the application of a finger pressure thereto, feelers carried by and positioned inside the casing and electrically connected to the respective output terminals; a circuit board carried by the rotor and having a predetermined pattern of electric circuits adapted to be selectively engaged with the feelers to complete a desired circuit configuration depending on the position of the rotor, a grounding terminal member carried by the casing, and a circuit element extending substantially between the location at which the finger pressure is applied to rotate the rotor and the grounding terminal member for establishing a discharge circuit through which an electrostatic charge set up in the body of the operator can be grounded.
