Cole's Series 3600 Spring Return rotary switch requires that manual torque be maintained at the desired switch position; releasing the force allows the spring to return the wiper to a normal, or detent position.

Spring return configurations of the 3600 Series are available in 30°, 36°, 45° indexing and one to six poles per deck.

Cole's Series 3600 one-inch diameter rotary switches are designed for aircraft, military use and demanding commercial applications in industrial controls, electronic test equipment and medical instrumentation.

Quality construction features include self-cleaning roller bearing contacts for high current carrying capacity and pure silver contact surfaces for constant low contact resistance. Hardened steel sprockets and ball bearing detent mechanisms provide smooth positive detent action and a mechanical life in excess of 100,000 cycles. Diallyl phthalate thermosetting plastic is used in the molded stators and rotors to provide the ultimate in mechanical and electrical properties.

In addition to the commercial version, a full QTL'd MIL switch is available.
