Precautions for correct use:
To attach the protective cover to the case, hold the cover in almost parallel to the case and then push it to the case. If the cover is pushed diagonally, the rubber packing may slip off and degrading the seal ability of the switch.
Note:
Rubber material is oil-proof rubber(NBR).
