The correct usage method for spring contact fingers is as follows:

1. Install the spring contact finger on the device to make contact and lock it.

2. Adjust the position of the spring contact finger to align with the surface of the equipment.

3. Adjust the compression of the spring to ensure appropriate contact pressure with the contact finger.

4. Regularly check the pressure of the spring contact finger to ensure good contact with the equipment surface.

During use, if you need to adjust or replace the spring contact finger, please make sure to turn off the power first to avoid accidents during equipment operation.
