Rotary coded switches Rotary coded switches BCD (10 position) and Hexadecimal (16 position), real and complementary codes. Fully sealed and suitable for flow soldering and solvent cleaning, these switches have a black polyamide casing (UL94 rated) and bold white characters. choice of low profile screwdriver-operated, knurled knob or large easy-to-operate colour coded knobs. Gold plated wiping contacts for reliable low level switching. If you have a volume requirement for a product variant not shown on this sheet please contact us.
