Abstract:
There is provided a power supply device including: a main power switch; an auxiliary power switch; a power supplying switch; a relay having a relay contact and an excitation coil that, in an excited state, closes the relay contact, and, when the excited state is cancelled, opens the relay contact; a control section effecting control such that, when the main power switch is in an on position and the auxiliary power switch is in an on/off position, the power supplying switch is turned on/off; and a driving section that drives the relay such that, when the main power switch is in an on position and the auxiliary power switch is in an on position, the excitation coil is excited and maintain the excited state, and, when the auxiliary power switch is in an off position, cancels the excited state of the excitation coil.
