Switch Ratings
NOTE: Pneumatic switches must be used with clean, dry air or gas. All switches include a
pre-wired terminal block. These switches have higher current ratings for SPDT than DPDT.
Periodic inspections are necessary to keep the switch in good working order. SOR recommends
a systematic program of preventive maintenance be implemented at the time of installation. The
following precautions are important and will help keep your switch in top operating condition.
Keep the switching mechanism clean. Never leave the cover off longer than absolutely
necessary. There is no need to lubricate any part of the switch.
Inspect switches and wiring monthly. Dry contact switches should be inspected for
excessive wear and misalignment. Pneumatic switch connections and tubing should be
inspected for cracks and air leakage. Repair or replace as required.
Do not operate switches that are defective or malfunctioning. When replacing parts,
refer to Replacement Instructions supplied with the parts and follow instruction
carefully. When in doubt, contact the factory or the SOR representative in your area.
