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.

POSITION SETTING FOR MRX & MRY MODELS
Mounting Hardware
Packaged Loose with Each Switch
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.
AT513M Hex Face Nut
AT507M Locking Ring
AT509 Lockwasher
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.
Factory Assembled:
Hex Nut
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.
