By News Author | May 16, 2016

Economical RM Series rotary switches deliver 50% reduction in board space for building automation, lighting controls, telecom, & audio equipment

C&K Components, a leading global manufacturer of electromechanical switches has released its smallest diameter rotary switch series, providing design engineers with a switch option that reduces board space by 50%. Available with two to eight positions, the new RM Series single-pole rotary switches feature an ultra-miniature 9.2mm body diameter and gold-plated contacts for reliable operation.

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

“The new RM Series switches have the smallest footprint of any rotary switch we’ve ever made available,” said Paul DiLorenzo, Global Product Manager at C&K Components. “In addition to the compact dimensions, this series also delivers the lowest cost rotary switch solution for applications that require reliable multi-position switching.” 

Available as a single-pole rotary switch with two to eight positions, the new, 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 0.5A at 24VDC and 0.2A at 48VDC, with insulation resistance of 100MΩ at 500VDC, and dielectric strength of 500VAC 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.

RM Series switches are available from C&K’s extensive global sales and distribution network. Samples are available immediately, and production volumes are available with four-week lead times.
