Cole's series of one-half inch encoded switches for direct logic level interfacing derive from the MIL-S-3786, MIL-S-22710, SERIES 1800 rotary selector switches, and feature the same mechanical quality as that series. The hexadecimal switch is also available in BCD, Octal, and Reflected Gray code notation, standard. Custom user codes are available on request.

Unlike other switches being introduced, the COLE 1800 series encoded switches anticipate both high-rel use, and the essentially dry circuit conditions of extremely low current switching; they offer 25,000 minimum life cycle and gold contacts - not found on most comparable units.

The switch is available in 221/2, 30, 36 and 45 degree indexing, with or without adjustable stops.

Quality construction, including materials that meet the strictest standards, allows these subminiature switches to combine high current switching capacity with constant low contact resistance. Long life and high reliability are assured by exceedingly stringent inspection and testing procedures.
