Working principle: when the electric box is used, the change-over switch body 1 is connected into the electric box for a hospital through the mounting holes 12 formed in the periphery of the mounting plate 11, the change-over switch body 1 is mounted and fixed, a commercial power source is connected into the wiring holes 32 above the wiring board 31 at the bottom of the main power source switch blade 33, a standby power source is connected into the wiring holes 32 above the wiring board 31 at the bottom of the standby power source switch blade 34, and then the wiring holes 32 below the wiring boards 31 at the bottom of the two change-over switch blades 3 are connected with a common circuit through wires respectively, so that the work of connecting the change-over switch body 1 into the circuit is completed.
When the change-over switch body 1 works normally, the change-over switch body 2 is used for adjusting the change-over switch 3, so that the main power switch 33 in the change-over switch 3 controls one end of the change-over switch body 1 to be connected with a commercial power supply, and the mode change-over switch on the change-over switch body 1 is switched to an automatic mode, at the moment, the change-over switch body 1 is in an automatic switching state, the knob pointer 22 above the change-over switch seat 2 points to one end of the main power switch 33, and the change-over indicator lamp 23 in the direction is lightened.
When the electric box is required to be checked and repaired during normal power consumption of a hospital, a worker firstly starts the anti-false touch switch 6 to enable the change-over switch body 1 to be in an anti-false touch mode, at the moment, the anti-false touch indicator lamp 61 on one side of the anti-false touch switch 6 turns yellow to indicate that the change-over switch body 1 of the worker is in an overhauling state, after the anti-false touch switch 6 is started, the electric rod 25 stretches to enable the lock catch 26 to leave the clamping groove 72, and then the protective cover 7 can be opened in a sliding mode, the worker pulls the protective covers 7 at two ends towards two ends, wherein the magnetic blocks 314 above the electromagnetic disc 313 are stressed upwards under the action of the electromagnetic disc 313 in the process, and after the protective cover 7 completely passes through the magnetic blocks 314, the magnetic blocks 314 are ejected out to limit the protective cover 7.
When the protective cover 7 is completely pulled open, the linkage protruding block 73 on the inner side of the protective cover 7 pushes the tail end of the driving plate 51, so that one end of the driving plate 51, which is close to the knife rotating shaft 37, abuts against the switch knife 3, and then the driving plate 51 is located above or below the limit protruding block 38 on the knife rotating shaft 37, the knife rotating shaft 37 is limited, the knife rotating shaft 37 is prevented from rotating randomly, the magnetic disc 313 is electrified to generate magnetic force, the magnetic force is opposite to that of the magnetic block 314, the magnetic block 314 extends upwards due to homopolar repulsion, the opened protective cover 7 is limited through the wedge-shaped structure above the magnetic block 314, the protective cover 7 is prevented from being retracted, the electromagnetic disc 313 on one side of the main power knife 33 is connected with the electric output end of the main power knife 33, when the main power fails, the electromagnetic disc 313 on one side of the main power knife 33 is powered off, the magnetic block 314 and the electromagnetic disc 313 are attracted and fall down, and then the protective cover 7 is retracted, the error-preventing component closes the switch seat 2 to actively rotate and drives the main power knife 33 to switch, and further the switch body 1 is disconnected from the main power supply and the standby power supply is ensured, and the normal power consumption knob of the hospital is ensured.
