Solder Lug
The .039" x .079" (1.0mm x 2.0mm)
oblong hole accommodates one solid
or one stranded 20-gauge wire or two
22-gauge wires.
PCB Mounting
Solder lug terminals are spaced
.100" x .200" (2.54mm x 5.08mm).
This enables PCB mounting which can be
accomplished by elongating PC board
holes to .080" (2.03mm).

The electrical specifi cations shown are determined at a basic temperature of 25C.
LED circuit is isolated and requires external power source. Single element LED is colored in OFF state.
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.

Cap Removal
1. Have cap in extended
position (not latchdown) for
alternate action models.
2. Use the grip slots on the
sides of the cap and pull it
out of the switch.
LED Polarity & Orientation in Lamp Socket
For AT624, AT629, AT630: Insert the LED with the
D fl at opposite the black dot molded inside the
switch lamp socket. For AT633: Insert the LED with
the Black Dot on the terminal to the right.
Cap Replacement
1. Match the prongs on
the cap base with the
projections in the switch,
at the same time ligning
the spring clips on the
cap with the indentations
in the switch.
2. Press fi rmly in place.
Super Bright LEDs AT624, AT629,
& AT630 are electrostatic sensitive.
