01
A partitioned plastic guard is supplied with each switch to provide insulation between terminals.
Installation steps:
(1) Identify wire-to-terminal connections.
(2) Thread wires through the guard.
(3) Solder the connections.
(4) Push the guard fully onto the switch body.

LAMP CODES & SPECIFICATIONS
Electrical specifications are determined at a basic temperature of 25°C. Lamp circuit is independent of switch operation.
For dimension drawings of lamps see the
Accessories & Hardware Index.
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.
