Klixon 20TC series aircraft circuit breakers

The snap–on actuators are available on request in a variety of colors, styles and indication markings designed to provide a stylish console appearance to the panels of light aircraft.

Several different types of actuators are available. The translucent actuator permits quick identification of the actuator position under low ambient lighting conditions by emitting a soft glow from a light source, such as an edge–lighted panel. Colored actuators will be hot letter stamped in white. White and translucent actuators will be stamped in black.
