See leaning specifications in Supplement section. MR, MRF, & MRK models have not been tested for UL recognition or S 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.
Half-Inch Diameter Process Sealed Rotaries Distinctive haracteristics Low profile body of MRF model accommodates space limitations required for P mounting. For the MR and MRK bushing mount models, the range of behind panel body depths is. to. (8.mm to.0mm). Positive detent mechanism for distinct feel and audible feedback. Metal bushing and housing construction increases durability. djustable stopper plate allows position settings. High contact reliability achieved by the self-cleaning contact mechanism. reak-before-make contact timing with sliding contacts in MR and rotary contactor disk in MRF and MRK models. Interior housing seal and molded-in P terminals, plus shaft rubber o-ring on MR and MRK and polyamide cover on MRF model, allow cleaning after automated soldering.

Turn the shaft counterclockwise to the extreme left by using a screwdriver.. Inside the cover is a magnifying lens which would be positioned over the number which is to be the maximum position used; when the cover is then snapped into the switch, the projection beside the lens fits into the correct hole for setting the stop. MRK & MR Models. Using the actuator knob, turn the shaft counterclockwise to the extreme left. If the shaft is not turned counterclockwise to the extreme left, proper setting cannot be achieved. t this extreme position, the white line on the knob points to the number position shown on the side of the switch.. Remove the knob from the shaft and loosen the nut far enough to allow raising the stopper plate, plus washer(s), for resetting to the desired position.. 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.. Tighten the nut (beveled side up) firmly against the stopper plate.
