Indicators
The HB2 pushbuttons have not been tested for UL recognition or CSA certification.
These switches are designed for use in a low-voltage, low-current, logic-level circuit.
When used as intended in a logic-level circuit, the results do not produce hazardous energy.

Subminiature Audio/Video Pushbuttons
Series HB2
Toggles
Quiet actuation combined with crisp tactile feedback suited for broadcast equipment.
Full face illumination with choice of red/green or red/yellow
bicolor LEDs, as well as simultaneous bicolor illumination
which produces amber.
D
Option of legends on caps or film insert.
Compact design with short body .669” (17.0mm) from
PCB to top of cap and .295” (7.5mm) square cap.
Sliding Twin Crossbar (STC) mechanism provides
unequalled logic-level reliability, contact stability,
smooth positive detent actuation, and long life.
Crimped power terminals ensure secure PCB mounting
and prevent dislodging during soldering.
Suitable applications include broadcast, telecommunication,
and medical equipment, as well as measuring instruments, etc.

The electrical specifications shown are determined at a basic temperature of 25°C.
LED circuit is isolated and requires external power source.
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.
