A switch device (10) includes a circuit board (14) disposed in a tubular holder case (18), a control button (34) disposed for movement along the longitudinal directions of the holder case (18), the control button (34) being actuated by pressing from outside of the switch device (10), and a switch unit mounted on the circuit board (14), the switch unit being actuated in response to rearward movement of the control button (34) by pressing. A coil antenna (194) is disposed rearwardly of the control button (34) and has an outside diameter which is substantially the same as an outside diameter of the control button (34). |
