Half-Inch One Deck Rotary Switch

The ultimate in a one half-inch rotary selector switch, the Cole series 1800 is engineered to meet or exceed applicable MIL-S-3786, style SR20 requirements. A QPL version is also available.

The Series 1800 enclosed switch was designed for critical ordnance applications, and demanding usage in aircraft, medical and industrial controls and instrumentation, as well as electronic equipment. This switch is available with 1 pole, 2 to 10 positions, and 2 pole, 2 to 5 positions.

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.

Available in standard solder lug or printed circuit terminations, the Cole Series 1800 and its unique design renders the switch resistant to water, contaminants and most solvents.
