Operation switch device
First Claim
1. An operation switch device, comprising:
- a circuit board;
first and second push switches disposed on the circuit board to have a determined height above the circuit board, each of the push switches including a movable part exposed to an outside for reacting to an external pressing operation;
first and second touch detecting electrodes formed on the circuit board respectively in proximity to the first and second push switches;
an operation detecting circuit connected with the push switches and the touch detecting electrodes; and
an operation member made of dielectric material and disposed to oppose the circuit board with the first push switch interposed between the operation member and the circuit board, the operation member including a rib part projecting toward the first touch detecting electrode on the circuit board to reduce a distance between the operating member and the first touch detecting electrode, the rib part including a cutaway part to increase a distance between the operating member and the second touch detecting electrode, and the operation member being displaceable such that the pressing operation on the operation member causes depression of the movable part of the first push switch provided under the operable member;
wherein the operation detecting circuit detects a touch operation on the operation member using the first touch detecting electrode formed in proximity to the first push switch on the circuit board, and detects the pressing operation on the operation member using the first push switch.

Abstract
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.

11. An operation switch device, comprising:
-
a circuit board; first and second push switches disposed on the circuit board, each of the push switches including a movable part configured to move in response to a pressing operation; first and second touch detecting electrodes formed on the circuit board respectively in proximity to the first and second push switches; an operation detecting circuit connected with the push switches and the touch detecting electrodes; and an operation member made of dielectric material and disposed to oppose the circuit board with the first push switch interposed between the operation member and the circuit board, the operation member including a rib part projecting toward the first touch detecting electrode on the circuit board to reduce a distance between the operating member and the first touch detecting electrode, the rib part including a cutaway part to increase a distance between the operating member and the second touch detecting electrode, and the operation member being displaceable such that the pressing operation on the operation member moves the movable part of the first push switch provided under the operable member; wherein the operation detecting circuit detects a touch operation on the operation member using the first touch detecting electrode formed in proximity to the first push switch on the circuit board, and detects the pressing operation on the operation member using the first push switch. - View Dependent Claims (12)
