LED SPECIFICATIONS
The electrical specifications shown are
determined at a basic temperature of 25°C.
Center LED is an integral part of the switch.
LEDs are not sold separately.
LED circuits are isolated and require an
external power source.

Install LED into LED Holder
(quantity 2).
Switch/Rectangular Cap assembly has 3 LEDs
to achieve bright and even illumination.
Solder LEDs and LED Holders
into PCB.
One LED (in center of switch bottom) is an
integral part of the switch; the other 2 LEDs
and 2 LED Holders are packaged separately.
Solder switch into PCB making
sure that the two outer LEDs
and LED Holders clear the bot-
tom side opening of the cap.
