Abstract

See full text

A switch status detection device includes a power source, a first resistor, a first switch, a control device, and a first capacitor. The first resistor has one end connected to the power source. The first switch is configured to switch between a connected state and a disconnected state of a first contact point, provided on a first current path between the other end of the first resistor and ground. The control device detects an on/off status of the first switch, on a basis of a voltage at the other end of the first resistor. The first capacitor has one end connected to the first contact point at a position on the first current path on a side of the first resistor with respect to the first contact point, and the other end connected to the power source or the ground.
