Subminiature Smooth Actuation Pushbuttons
Series NP01
Distinctive Characteristics
Soft touch actuation achieved by mechanical silicon rubber structure (patent pending).
Distinct, long stroke of 1.5mm (.059”).
Entire cap is fully illuminated with single or bicolor LED.
Compact design with dimension of 12.5mm (.492”) from
PC board to top of cap.
Alternating legend options (patent pending) with
bicolor LED.
Available in both high (2.5N) or standard (1.5N)
operating force.
Gold plated contacts provide high reliability.
Crimped terminals ensure secure PC mounting
and prevent dislodging during soldering.
Molded-in terminals prevent entry of flux, solvents,
and other contaminants.
Nonilluminated models available.

LED COLORS & SPECIFICATIONS
LEDs are an integral part of the switch and not
available separately. The electrical specifications
shown are determined at a basic temperature of
25°C.
If the source voltage exceeds the forward voltage,
a ballast resistor is required.
