Switch device

A switch device, comprising:

• an elastically deformable panel including operating portions, each of the operating portions being configured to receive a push-operation and assigned to a corresponding one of operation functions;
• movable members each configured to be moved by the push-operation performed on a corresponding one of the operating portions;
• a detector configured to detect movement of the movable members moved by the push-operation;
• and
• a sensor sheet arranged between the panel and the movable members to detect at least one of contact of a human body part with the panel, approach of a human body part toward the panel, and the push-operation performed on the panel, wherein:
• the sensor sheet includes a sheet base configured to be bent and deformed, and electrodes each arranged on the base sheet for a corresponding one of the operating portions;
• the sheet base includes a gap formed between adjacent ones of the electrodes;
• and
• the electrodes each include a wiring part, and wiring parts of at least two of the electrodes are connected to one another other.
