A buckle switch-and a microcontroller are provided. A power supply is connected to the buckle switch, which switches the connection with the power supply between a connected state and a disconnected state. The microcontroller is connected with the buckle switch and includes a removal switch input port and a removal control port. The removal switch input port detects the state of the buckle switch. The removal control port is connected to the buckle switch-via a pull-down resistance and controls whether the pull-down resistance operates. The microcontroller controls the removal control port such that the pull-down resistance does not operate when the buckle switch is in the connected state and such that the pull-down resistance does operate when the buckle switch is in the disconnected state.
