Rockers Toggles Series LW Power-Rated Snap-in Rockers Programmable Illuminated PB Numerous lighting effects achievable by using white or clear rocker with colored filters or lamp covers, plus using different colors on each side of rocker. Snap-in mounting allows fast, easy installation of switch into panel. Rotaries Keylocks Stainless steel retaining clips provide secure mounting over a wide range of panel thicknesses. Slides Dual incandescent or neon lamps operate independently of each other. Tactiles Front panel relamping. Tilt Stationary lamp sockets are independent of rocker actuation, protecting lamps from damage due to shock and vibration. Touch Switch contacts are rated at 10 amps 125V AC which makes these devices well-suited for various power switching applications.
