(54) Electronic equipment


(57) A switch device has an operation member by which a two-pole contact part can be manually turned on or off, and actuating means by which a one-pole contact part of the two-pole contact part can be automatically turned on or off. When the two-pole contact part is manually turned on by operating the operation member, a one-pole contact part of the two-pole contact part can be turned off by actuating the actuating member, based on a driving signal outputted from a control system circuit in response to an external control signal. When the one-pole contact part is off, it can be turned on by actuating the actuating member, based on a discharge current outputted from an electricity storage circuit according to an external control signal.
