Small diameter rotary switch option reduces board space by 50%

Available from Digi-Key, C&K Components 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 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 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 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 an operating force of 270+/-100gf cm. The series contacts are rated for 0.5A at 24VDC and 0.2A at 48VDC, insulation resistance of 100Mohm at 500VDC, and dielectric strength of 500VAC for one minute. Operating temperatures for the series span from -40C to 8°C and the switches also feature insert moulded terminals to prevent contamination during soldering.
