PURPOSE: A power supply with a built in switch is provided to previously prevent gas leakage and dielectric breakdown due to epoxy molding of a capacitor by directly connecting high voltage in an interior of the switch to provide state information of the power supply. CONSTITUTION: A power supply with a built in switch comprises a high pressure side terminal(10) serving to a capacitor, a ring installed outside the high pressure side terminal and molded with epoxy, a detecting terminal(12) symmetrically installed around the ring with constant interval, and a connection terminal(13) installed under the detecting terminal for facilitating single-directional installation. Through the connection terminal, power supply is connected with a control box. A bushing is installed between the high pressure side terminal and the detecting terminal with constant interval and is molded with epoxy.
