Where is the air switch reset key?

Usually, the air switch has a test key instead of a reset key. When the air switch trips, it will not jump to the correct position. Pull the brake to the correct position before closing. The earth leakage protection switch with reset key can only be turned off after the reset key.

1. The reset of the leakage protection switch is located in the upper right corner. The T key is marked as a test key, and the small print next to it means: press it once a month. Press once a month to ensure that the leakage protection function is effective.

2. After pressing the test button, there will be a resistor across the ends of the leakage circuit breaker, which will generate a certain residual current to simulate the residual current when leakage occurs, so as to test whether the leakage circuit breaker can work normally. After pressing the test button, it should trip immediately, otherwise the leakage circuit breaker is faulty.

3. The square button below the T button is the reset button, which will automatically pop up when the idle switch trips automatically for some reason, but will not pop up when the switch is turned on manually. Manual internal brake opening and automatic tripping can be distinguished. When the reset button pops up, you need to press the reset button when you close it again, otherwise it cannot be closed normally.

The above is related to air switch tripping, I hope it will help everyone!
