<p>A switch device (1) includes a circuit substrate (6) provided with a fixed contact, a rubber (8) sheet having dome-shaped protuberances (8a) disposed on the circuit substrate (6), an actuator (9) that is swingably held, a holder (12) that is held moveable in the vertical direction and has a lower end portion on two protuberances of the protuberances, and a rotatable knob (13) axially supported at the holder (12) within a housing. The actuator is provided at the side of the rotatable knob (13). A drive portion (13b) attached to the rotatable knob extends outward of the holder so as to be engaged with the actuator. When the rotatable knob (13) is turned, the drive portion swingably rotates the actuator such that the swing end pushes the two protuberances (8a). When the rotatable knob (13) is pushed, the holder (12) moves down accordingly to push other of the protuberances (8a).</p> |
