10mm Washable DIP Rotaries
Series DR
Distinctive Characteristics
Highly visible legends and choice of screwdriver, shaft, or
dial adjusted actuators provide trouble-free code setting.
Knob actuator also available.
Detent mechanism gives crisp, positive action for
accurate switch setting.
Sealed construction prevents contamination and
allows automated soldering and washing.
Optional panel seal mount available in
the DRA model which can be installed
with behind-panel o-ring for protection
against splashed or sprayed liquids.
Real or complement code setting
identified by color-keyed actuator.
Crimped terminals ensure secure PC mounting
and prevent dislodging during soldering.
Self-wiping contacts assure contact reliability and continuity.
Compact dimensions and low profile allow high density mounting
and close stacking of PC boards.
Ultrasonically welded case, o-ring sealed actuator, and insert molded
terminals seal out flux and other contaminants.

Standards & Certifications
Flammability Standards:
UL Recognition
or CSA Certification:
UL 94V-0 rated actuator, housing, case, & base
The DR series rotaries 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.
