Nidec Copal RS/RG Rotary selector switch

Nidec Copal RS/RG Rotary selector switch

The RS/RG series from Nidec Copal (formerly Fujisoku) is a premier choice for technical applications requiring accurate and repeatable circuit selection. The Nidec Copal RS/RG Rotary selector switch is built with a focus on signal integrity, utilizing a mechanism that allows for up to 12 positions in a single-pole configuration. This high density of switching options within a small footprint makes it indispensable for modern instrumentation and control interfaces.

Designed for seamless integration into production workflows, the RS/RG series features excellent sealing properties that make the units fully washable. This allows the switches to undergo standard automated cleaning processes post-soldering without the risk of internal contact degradation. Furthermore, the availability of both shorting and non-shorting switching timing allows designers to tailor the switch behavior to prevent or enable momentary contact between positions, depending on the specific safety and functional needs of the circuit.
