The button self-locking switch is called a safety lock.
Safety locks are used occasionally and are a type of lock. It is to ensure that the energy of the equipment is absolutely turned off and the equipment remains in a safe state. Locking prevents equipment from being accidentally activated, causing injury or death. Another purpose is to serve as a warning, such as fire extinguishing equipment locks in shopping malls, which are different from the general anti-theft function of locks.
Lockout/Tagout is referred to as LOTO, and the concept originated from the United States. When equipment or tools are being repaired, maintained or cleaned, the power source associated with the equipment is cut off. The device or tool will then fail to start. At the same time, all energy sources (power supply, hydraulic source, air source, etc.) are turned off. The purpose is to ensure that workers working on the machine or related personnel will not be injured.

1. Locks should not be exposed to rain for a long time. Falling rainwater contains nitric acid and nitrates, which will corrode locks.
2. Keep the lock clean at ordinary times, and do not let foreign matter enter the lock core, which will make it difficult or even impossible to open.
3. Regularly inject lubricating oil, graphite powder or pencil powder into the lock core to help reduce the oxide layer left by long use.
4. Pay attention to the thermal expansion and contraction caused by the weather (humid in spring, dry in winter) to ensure that the gap between the lock body and the key is reasonably matched to ensure smooth use of the lock.
