A fixing module is for fixing a push button or emergency stop button or rotary actuator of a control and signaling device. In an embodiment, the fixing module is constructed from a top housing part and a bottom housing part, each including a cuboidal structure with a top side, an underside and four side parts connecting the top side to the underside. In at least one embodiment, on the top side of the bottom housing part, a material that extends at least partially in this plane and has a grounding function is formed or an electrically conductive component made of metal with a grounding function is arranged.

A key switch includes a base, a key cap, a first support member and a second support member. The key cap is disposed with respect to the base. The first support member and the second support member are disposed between the key cap and the base. The first support member has a first linkage structure. The second support member has a second linkage structure. The first linkage structure and the second linkage structure abut against each other, such that the first support member and the second support member rotate synchronously with respect to a horizontal axis. When one of the first support member and the second support member horizontally moves with respect to the other one of the first support member and the second support member within a predetermined range along the horizontal axis, the first linkage structure and the second linkage structure keep abutting against each other.

A switch device includes a switch part that is installed on a steering wheel of a vehicle and that includes an operation knob and an electromagnetic element for detecting an operation on the operation knob and causing a vibration of the operation knob, and a control unit that makes the operation knob vibrate. The control unit controls the electromagnetic element to vibrate under a predetermined condition so that vibration is transmitted to a hand of an occupant holding the steering wheel.
