POSITION SETTING FOR MRA, MRF, & MRK MODELS
Each switch is supplied with the stopper set for the maximum number of positions allowed for that model. Prior to installation,
the desired position setting should be made. Contact factory for continuous rotation.

1. Remove the protective cover from the switch body.
2. Turn the shaft counterclockwise to the extreme left by using a screwdriver.
3. 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.

1. 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 can-
not be achieved. At this extreme posi-
tion, the white line on the knob points
to the number 1 position shown on the
side of the switch.
2. Remove the knob from the shaft and
loosen the nut far enough to allow rais-
ing the stopper plate, plus washer(s),
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 func-
tioning cannot be assured if the stopper
plate is not properly positioned.
4. Tighten the nut (beveled side up) firmly
against the stopper plate.
