These devices are not process sealed. Hand clean locally using alcohol based solution.
The DB Series pushbuttons have not been tested for UL recognition or CSA certification.
These switches are designed for use in low-voltage, low-current, logic-level circuit.
When used as intended in a logic-level circuit, the results do not produce hazardous energy.

Distinctive Characteristics
Both PCB and panel mounting options available.

Programmable Illuminated PB
Choice of cap sizes in .315” (8.0mm) and .394” (10.0mm)
diameter cap design for simple, snap-on installation.
Pushbuttons
Light Touch Miniature Pushbuttons
High torque bushing prevents rotation and separation
from metal frame during installation.
Keylocks
Stainless steel frame resists corrosion.
Rotaries
Snap action contacts give smooth actuation, short
stroke, light touch, and audible feedback. This
mechanism also provides long mechanical life.
Slides
Molded-in terminals prevent entry of solder flux,
dust, and other contaminants.

Tactiles
.100” x .100” (2.54mm x 2.54mm) terminal spacing
conforms to standard PC board grid spacing. Round
terminals for easier through-hole mounting on PC boards.
