A switch device includes two fixed contacts and a movable contact of which position is changed when an operation unit is operated to selectively contact the fixed contacts. The switch device also includes a snap action mechanism that switches a contact state of the movable contact with the fixed contacts by deforming a spring portion in accordance with an operation amount of the operation unit. The switch device also includes a control unit that determines an operation state of the operation unit based on a detection signal received from the fixed contacts and the movable contact.

Provided are a control box and electric furniture. In the control box, a wireless charging assembly is pressed downward by an external force such that the wireless charging assembly moves downward relative to the control box body to drive or push the pressing portion toward a control switch. When the pressing portion abuts against the control switch, the control switch acts. After the external force is removed, the wireless charging module moves away from the control switch under the action of an elastic resetting portion so that the pressing portion is separated from the control switch.
