The switch cannot be pushed up for the following reasons:
Overload protection: The switch is a kind of protection to prevent circuit overload. Device, when the circuit is overloaded, the switch will automatically trip to avoid safety problems such as circuit short circuit and fire. If the circuit load exceeds the rating of the switch, or there is a short circuit problem, the switch will trip. If the switch cannot be pushed up, there may be an overload or short circuit problem in the circuit.
Switch failure: The switch may also be unable to be pushed up due to its own internal fault, such as poor contact of the switch, burnt coil, etc. If the switch fails, you need to contact professional electrical maintenance personnel for repair or replacement.
Water and moisture: If the area of the electric panel is damp or filled with water, it may cause the switch to fail to move up smoothly. In this case, it is necessary to cut off the power and remove the humidity before proceeding.
Aging of the electric switch: After the electric switch has been used for a long time, the internal parts may wear and age, causing the electric switch to fail to work properly. If the circuit breaker has been in use for a long time, you may consider replacing it.
No matter what reason causes the switch to fail to be pushed up, it is necessary to cut off the power and eliminate the fault before operating to ensure safety. If you are not familiar with technical operations, it is recommended to contact professional electrical maintenance personnel for processing.
