C&K Components has announced what it describes as its smallest diameter rotary switch series. According to the company, the RM series single-pole rotary switches feature an ultra-miniature 9.2mm body diameter and gold-plated contacts for reliable operation to slash board space by half.

Intended for next-generation building automation systems, including lighting and fan controls, test and measurement equipment, and telecommunication and radio systems, the rotary switches deliver economical sub-miniature solutions for applications that require reliable multiple-position switches with positive detents that provide tactile feedback, detailed the company.

Available as a single-pole rotary switch with two to eight positions, the 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 moulded terminals to prevent contamination during soldering.

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