Tips for Choosing a Power Switch Lock

The power switch lock is a type of safety padlock with advantages such as simple structure, easy operation, convenient installation, long service life, and strong reliability. It is mainly used in industrial settings in China to provide protection.



Plating:
When purchasing, pay attention to the lock’s plating—particularly whether the door handle will fade. Generally, a good lock’s protective layer (the electroplating layer) will not easily oxidize or wear. Since the coating of the handle affects the overall aesthetics of the room, this point should not be overlooked.

Match the Door:
When selecting a lock, first ensure that it matches the opening direction of your door, so the door can be opened and closed more easily. Second, pay attention to the width of the door frame. For a 90mm door:

  • If the door frame is between 90mm and 100mm, choose a 60mm latch of a standard spherical lock.

  • If it is more than 100mm, choose a lock with a larger cover, i.e., a 70mm latch.
    In addition, both the thickness of the door and the lock should be properly matched—this is an important consideration.

Durability:
Durability is closely related to the material of the lock. You can judge this through looking, weighing, and listening:

  • Look at the appearance and color. Pure copper locks are usually polished and sanded, showing a deeper yet natural color compared with copper-plated locks.

  • Weigh the lock. Pure copper locks feel heavier, while stainless steel locks are noticeably lighter.

  • Listen to the unlocking sound. Copper-plated locks sound dull, while stainless steel locks sound clear.

Feel:
The feel of a lock depends on its spring. The quality of the spring determines both the comfort of operation and the service life. Poor-quality springs can cause the handle to sag, reducing the lock’s lifespan. When purchasing, try the lock yourself to test the resilience of the spring. A good spring should feel soft and balanced—not too hard and not too soft.

Through the above points, we’ve explored key considerations and perspectives for selecting a power switch lock. With this knowledge, you should now have a deeper understanding of power switch locks. Indeed, locks are an essential part of daily life, safeguarding our security.
