Oil-proof and chemical-proof characteristics
The rubber elastomer swells when exposed to oil and chemicals.
The extent of swelling will vary widely depending on the type and
amount of oil and chemicals.
Check with the actual oil or chemicals used.
In particular, be aware that solvents such as freon, chlorine, and
toluene cannot be used.
Washability [ABJ (BJ) and ABS (BS)]
Do not clean the switch. Doing so can cause problems.
