Since the development of electrical switch lockouts, we all need very good products, but even the best products will occasionally have small problems in life. Let us tell students together about the general psychological problem analysis of their own electrical switch locks, and how to solve the teaching methods. The lock shackle does not run: Most of the lock shackle are large tolerances in the shape of the lock shackle during calibration. Insert the key into the lock cylinder, open other positions, rotate until it is fixed, and tap gently with a small hammer. The lock does not turn: Because the friction is not large, the electrical switch lock is not used for a long time, and the lock is rusted. A small amount of diesel and gasoline are poured on the lock, which can effectively solve these problems.

The key is stuck in the lock: If you find that the key is broken from the root, you can directly clamp it with tweezers or other tools. If the lock core is broken in the middle, you can only remove the 7-hole seal in the lock, take it out and reinstall it, and seal it with aluminum wire. The key plug is blocked: The keyhole is usually sprayed with graphite, and pencil lead is usually used. Never pour lubricating oil into it.
