Operation switch device
An operation switch device includes a circuit board and a push switch disposed on the circuit board and including a movable part exposed to an outside for reacting to an external pressing operation. Also provided on the circuit board is a touch detecting electrode formed in proximity to the push switch. The operation switch device further includes an operation detecting circuit connected with the push switch and the touch detecting electrode, and an operation member disposed to oppose the circuit board with the push switch interposed between the operation member and the circuit board. The operation member is displaceable such that the pressing operation on the operation member causes depression of the movable part of the push switch. The operation detecting circuit detects a touch operation on the operation member using the touch detecting electrode, and detects the pressing operation on the operation member using the push switch.
