The present invention provides a multi-functional switch device and a steering switch device capable of combined operation of rotation operation and push operation, and which can be easily reduced in thickness. The switch device (1) is provided in the housing (19): a circuit board (6) provided with a fixed contact (7), a bulging portion (8a), a
rubber sheet (8) mounted on the circuit board (6) ), the
actuator (9) that can be held swingably, the holding member (12) that can be held up and down, and the knob (13) that is supported on the holding member. The
actuator (9) is arranged on the side of the knob, and the driving part (13b) attached to the knob extends to the outside of the holding member (12) to engage with the
actuator. When the operation knob is rotated, the driving part makes the actuator swing and rotate, and the swing end (9b) presses and drives the bulging part (8a) below; when the operation knob is pressed, the holding member (12) descends integrally to press and drive the lower The bulging part (8a).
