Distinctive Characteristics
Carefully designed light diffusion and filtering system produce bright,
full surface illumination with front panel relamping.
Spot illumination available in single and bicolor LEDs.
Choice of super bright LEDs in white, green, and blue
in addition to standard or bright red, amber, and
green LEDs.
Stainless steel clips provide secure mounting with a
wide range of panel thicknesses.
Latchdown feature gives indication of circuit status.
Audible and tactile feedback with smooth and
responsive operation.
Snap-action contact mechanism gives long
electrical life and sensitivity of actuation.
Combination solder lug and .110" quick connect
terminals are epoxy sealed to prevent entry of flux,
dust and other contaminants.
Panel sealed model meets IP65 of IEC529 specifications
(similar to NEMA 4 & 13).
Compact switch design minimizes behind panel depth.
Actual Size
Nonilluminated models available and shown in the
Pushbutton section.
Matching indicators available and shown in the
Indicator section.

LED CODES & SPECIFICATIONS
Electrical specifications are determined at a basic temperature of 25°C. LED circuit is independent of switch operation.
LEDs are colored in OFF state. For dimension drawings of lamps see Accessories & Hardware Index (page Y1).
If the source voltage is greater than rated voltage, a ballast resistor is required.
The ballast resistor calculation and more lamp detail are shown in the Supplement; see Supplement Index (page Z1).
