The present invention provides electronic equipment that can shut off and supply power to a primary power supplying circuit by automatic operations, directly shut off power to the primary power supplying circuit by easy manual operations based on the operator's will, and never fails to zero power consumption of the primary power supplying circuit during no use. The electronic equipment comprises: a primary circuit; a secondary power supplying circuit to which power is supplied from the primary circuit; a control circuit; a switch apparatus provided with a switch; and a capacitor, wherein the switch apparatus includes: an operation member for switching the switch between manual ON and OFF positions and an automatic ON/OFF position in which ON/OFF operations can be automatically performed; and a driving source for automatically operating the switch, wherein, in the automatic ON/OFF position, the driving source is driven by a signal from the control circuit or power supplied from the capacitor to automatically turn the switch ON or OFF, whereby power to the primary power supplying circuit can be automatically supplied or shut off, and wherein the operation member is manually operated to turn the switch ON or OFF, whereby power to the primary circuit can be manually supplied or shut off.
