Abstract
A switch device has a circuit unit that forms an electric circuit that detects at least one of disconnection and a short circuit of a wiring connecting an external device and the switch device, two terminals connected to the electric circuit, and configured to be connected to the wiring, a contact mechanism that moves in a movable direction to switch on and off of a contact of the electric circuit, and a circuit board on which the circuit unit, the two terminals, and the contact mechanism are disposed. The electric circuit comprises at least one resistive element. The circuit unit and the contact mechanism are disposed on an identical surface side of the circuit board. The resistive element is disposed in a direction perpendicular to the movable direction of the contact mechanism when viewed from at least a part of a movable range of the contact mechanism.
