The left side wall or the right side wall of the anti-error cover fixing frame is provided with a power supply receiving hole, and the power supply is arranged in the power supply receiving hole.

The light source is an LED light source, the power supply uses a button battery, and there are two or more colors of the light source. The color of the light source is divided into many kinds, which is beneficial to the identification of the working state of the pressing plate.

Beneficial effects: the anti-mistake cover is covered on the pressure plate, and the light source can emit light to show the difference. During the relay protection test, the pressure plate anti-mistake cover can distinguish which pressure plates are in the operating state and which pressure plates are in the non-operating state, which is the relay protection test. Security provides guarantees.
