LAMP COLORS & SPECIFICATIONS
The electrical specications shown are determined at a basic temperature of 25°C.
LED circuit is isolated and requires external power source. Polarity marks are on the bottom of the switch.
If the source voltage exceeds the rated voltage, a ballast resistor is required.
The resistor value can be calculated by using the formula in the Supplement section.
Ambient Temperature Range for lamps below: –25°C ~ +50°C.

A partitioned plastic guard is supplied with each switch to provide insulation between terminals.
Installation steps:
1. Identify wire-to-terminal connections. 3. Solder the connections.
2. Thread wires through the guard. 4. Push the guard fully onto the switch body.
