Setting Stops With Stop Pins
MA00, MB00, MC00 & MD00 Models Only:
The number of switch positions or stops are adjustable by means of stop pins provided with each switch. Switches are normally
shipped with stop pins and hardware in bulk, not installed. Without stop pins, switches have full 360º rotation and no stops.
Note that all two pole models begin to repeat when actuated 180º 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 180º 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.
Setting Stops With Stop Rings
ME00, MF00, MG00 & MH00 Models Only:
The number of switch positions or stops are adjustable by means of stop rings provided with each switch. These models are
normally shipped with stop rings and hardware in bulk, not installed. Without stop rings, switches have full 360º rotation and no
stops. Note that all two pole models begin to repeat when actuated 180º 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 bush-
ing
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 180º 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.
Hardware:
Two stop rings, mounting nut and lockwasher supplied standard.
