The utility model relates to the technical field of air switches, and discloses an air switch rapid re-power supply device which comprises a main body mechanism and an auxiliary mechanism, the auxiliary mechanism is located on the main body mechanism, and the main body mechanism comprises a first
butt joint, a first conducting strip, a first detection lamp and a limiting ring. The first conducting strip is fixedly installed at the right end of the first
butt joint, the first detection lamp is fixedly arranged at the left end of the first
butt joint, and the limiting ring is fixedly installed at the upper end of the first butt joint. According to the air switch rapid re-power supply device, a butted
electric wire touches the first conductive sheet, if the
electric wire is electrified, the first detection lamp emits light to prompt that the
electric wire is electrified, and if the electric wire does not emit light, the electric wire is not electrified, so that two electric wires which are electrified in the same way can be effectively prevented from being butted together during wiring, a secondary accident is avoided, and the service life of the air switch is prolonged. And the two butt joints of the device are provided with the detection mechanisms, so that the device is more convenient to use.
