| Miniature Power Level Rotaries Series MR Distinctive Characteristics Positive detent mechanism for distinct feel and audible feedback. Metal bushing and housing construction increases durability. Adjustable stopper plate allows 2-8 position settings. High contact reliability achieved by the self-cleaning contact mechanism. Break-before-make contact timing with various mechanism types: sliding contacts in MRX, contactor dish in MRY, and butt contacts in MRT models. Terminal types include PC-turret for MRX, turret for MRY, and solder lug for MRT models. Molded-in PC-turret and turret terminals prevent entry of flux and other contaminants.

Prior to installation, the desired position setting should be made. Contact factory for continuous rotation. 1. Using the actuator knob, turn the shaft counterclockwise to the extreme left. If the shaft is not turned to this extreme position where the white line on the knob points to the number 1 position shown on the side of the switch, proper setting cannot be achieved. 2. Remove the knob from the shaft and loosen the nut far enough to allow raising the stopper plate for resetting to the desired position. 3. Note the position numbers on the side of the switch; these correspond to the terminal numbers and stopper holes. Insert the stopper in the hole numbered for the maximum desired number of stop settings. Satisfactory switch functioning cannot be assured if the stopper plate is not properly positioned. 4. Tighten the nub (beveled side up) firmly against the stopper plate.
