The C&K E Series Sealed Miniature Toggle Switches offer a reliable solution for applications requiring protection against contaminants and electrostatic discharge. Constructed with a glass-filled nylon 6/6 case and brass actuator with an internal o-ring seal, these switches provide durability and resistance to harsh conditions. Available in various configurations, including single-pole, double-pole, and triple-pole options, they cater to diverse electrical needs. The switches find application in telecommunications, instrumentation, and medical equipment, ensuring dependable performance in critical systems. ESD protection is available through the F1 conductive bushing option, dissipating up to 20,000 V DC from the actuator to ground. A wide range of actuator colors and bushing options are available to meet specific design requirements.
