Common features The electrical rating of the unipolar SPDT switch for all O16 controls is: Օ 16(16)A 250V- N.O. or N.C.  1(1)A 250V~ on the opposite side. Connection to the pressure line: 7/16 - 20 UNF straight output male connector, 1/4 flared female connector. Cable input: 14mm insulating bushing for O16; for O52, P.G. 16 Refrigerant: equipment suitable for use with the most common gases.
