Switches are normally shipped with stop pins and hardware in bulk, not installed. Without stop pins, switches have full 360 rotation and no stops. Note that all two pole models begin to repeat when actuated 180 or more. To set stops, refer to figures 1 & 2. Orient switch so that terminal no. 1 is as shown. Turn actuator to position 1, using flats on bushing and terminal no. 1 as reference. Install CCW stop pin in hole designated `X'. Install second stop pin in hole number corresponding to the number of positions desired. Note that two pole models will begin to repeat when actuated 180 or more. To retain stop pins, use adhesive mylar washer included; see figure 3. All models except MX00 models have number of switch positions or stops pre-set at factory and are not adjustable. Hardware: Two stop pins, mounting nut, and lockwasher supplied standard.

These models are normally shipped with stop rings and hardware in bulk, not installed. Without stop rings, switches have full 360 rotation and no stops. Note that all two pole models begin to repeat when actuated 180 or more. To set stops refer to figures 4 & 5. Orient switch so that terminal no. 1 is as shown. Turn actuator to pos. 1 using flats on bushing and terminal no. 1 as reference. See figure 6 and install inner stop ring with short tab in hole designated `X'. Install outer stop ring with long tab in hole number corresponding to the number of positions desired. Note that all two pole models begin to repeat when actuated 180 or more. Use mounting nut and lockwasher to retain stop rings. All MEXX, MFXX, MGXX & MHXX Models (Except MX00 models): Number of switch positions or stops are preset at factory, but are user adjustable.
