The standard material for the Switch seal is nitrile rubber (NBR),
which has superior resistance to oil. Depending on the type of oil
or chemicals in the application environment, however, NBR may
deteriorate, e.g., swell or shrink. Confirm performance in advance.
The correct Switch must be selected for the load to ensure contact
reliability. Refer to Precautions for microloads in individual product
information for details.
