A device for a capacitance switch is provided to operate a desired switch since light transmitting a transmission unit lights up the identification symbol even though the device for the capacitance switch is installed in a dark space. A device for a capacitance switch includes a case(100), a printed circuit board(106), a conduction unit(112), a transmission unit(110), and a light source. An identification symbol for allowing identification of a switch function is printed on a front surface of the case. The printed circuit is installed segregatedly from a rear surface of the case. A conductive plate(107) is formed on the printed circuit board. Electricity is supplied between the rear surface of the case and the conductive plate. The transmission unit is installed in parallel to the conduction unit and transmits light. The light source irradiates the light to the transmission unit. The conduction unit and the transmission unit have an elasticity. The light source is installed on the printed circuit board and irradiates the light to a side portion of the transmission unit. An exterior surface of the conduction unit is plated with a conductor.
