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.
