Ideal for use in next-generation building automation systems, including lighting and fan controls, test and measurement equipment, and telecommunication and radio systems, the RM Series rotary switches deliver economical subminiature solutions for applications that require reliable multiple-position switches with positive detents that provide tactile feedback.

Available as a single-pole rotary switch with two to eight positions, the space-saving RM Series switches are equipped with either an extended shaft with one of two standard knob options, or a flush actuator with a screwdriver slot for adjustment. Gold-plated contacts provide reliable switch operating lifespans of 2,000 cycles, with operating force of 270+/-100gf cm. RM Series contacts are rated for 0.5 A at 24 VDC, and 0.2 A at 48 VDC, with insulation resistance of 100 MΩ at 500 VDC, and dielectric strength of 500 VAC for one minute. Operating temperature for the series spans –40° C to 85° C, and RM Series switches also feature insert molded terminals to prevent contamination during soldering. 

Samples are available immediately and production volumes are available with four-week lead times.
