Precautions for correct use:
Be sure that the clamp is inserted to the full depth, because the switch will not function properly if one of the clamps is improperly inserted. If the clamp is properly inserted up to the full depth, it will no slide out easily.
Note:
Rubber material is oil-proof rubber(NBR).
