Claims

[Scope of utility model registration request]

(1) an operating shaft that is operated by pressing with a fingertip, a rotor that is rotated by the operating shaft, a case that accommodates the operating shaft and the rotor, and a conductive pattern section provided on one of the rotor or the case; In a digital switch provided on the other side of the rotor or the case and comprising a contactor that switches the circuit by coming into contact with and separating from the conductive pattern part, a part or all of the operation shaft is made of a conductor, and the operation shaft A digital switch characterized in that a ground terminal is provided at a position where a conductive part inside a case of an operating shaft is closer than the distance between a fingertip and the conductive pattern part during a suppression operation.

(2) The digital switch according to claim 1, wherein the operating shaft is made of conductive plastic.

(3) The digital switch according to claim 1, wherein a conductive material is deposited on the entire surface or one continuous surface of the operating shaft.

(4) Utility model registration claim 1, characterized in that a conductive member is attached to the suppressing portion that contacts the fingertip of the operating shaft, and the tip of the conductive member approaches or contacts the ground terminal when the operating shaft is pressed. Digital switch as described in section.
