KNITTER-SWITCH MRS 9 Position SP9T Rotary Switch 100mA 16V DC PCB Mount Solder Terminal SP9T

KNITTER-SWITCH SP9T Rotary Switch model MRS 12V-19 is a high-quality miniature rotary switch intended for industrial and electronic automation applications. It features a 9-position selector with a single pole and On-On switch configuration, rated for a contact current of 100mA at 16V DC, suitable for low voltage electronic circuits and control panels.

The switch housing is made from fiberglass reinforced polybutylene terephthalate providing robust mechanical strength and electrical insulation properties, ensuring durability even in demanding PCB-mounted environments. Its compact form factor with 11.4mm width and depth, and a height of 9.8mm allows integration in space-constrained setups.

Equipped with solder-type terminals for PCB mounting, it ensures secure electrical connections. The switch has a mechanical life expectancy of 10,000 operations coupled with an operating force of 250 ± 100 gf.cm for tactile feedback and accuracy in switching.

The angle of throw is 40 degrees between each position, offering precise incremental switching through the 9 selectable positions. It is designed to operate reliably across a temperature range of -20°C to 80°C, suitable for a variety of industrial, laboratory, and manufacturing environments requiring rotary switch functionality.

Additional features include black non-illuminated actuators and a pin footprint spacing of 2.54mm between pins and 5.08mm between rows that complies with standard PCB layouts. The product complies with RoHS environmental directives and is manufactured in the Republic of Korea, signifying quality manufacturing standards.
