1. Classification from appearance:

① Brake plunger type: There is a column at the top of the micro switch, and the device presses the column from the top to turn on the switch.

② Sliding straight wheel type: There is a column on the top of the micro switch, and a roller on the column. The device presses the roller from the top to turn on the switch.

③ Pendulum bar with roller: A pendulum bar with rollers extends across the top of the micro switch. The device presses the pendulum bar from the top to turn on the switch.

④ Top small button type: A small button protrudes from the top of the micro switch, and the device presses this button from the top to turn on the switch.

⑤ Pendulum bar: A pendulum bar extends across the top of the micro switch, and the device presses the pendulum bar from the top to turn on the switch.

2. Classification from the performance perspective:

① Common micro switch: The most common micro switch, used in a normal temperature environment and humidity environment.

② High temperature micro switch: In order to prevent the micro switch from being damaged in a high temperature environment, it is generally used at a temperature above 60 degrees and 120 degrees.

③ Waterproof micro switch: In order to prevent the micro switch from being damaged in a damp and cold environment.

④ Explosion-proof micro switch: mainly used in high dust environment.

⑤ Outdoor micro switch: If the micro switch is used outdoors for a long time, it is very susceptible to environmental hazards, so it should be sealed, waterproof and dustproof.
