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.

4. Tighten the nub (beveled side up) ﬁrmly against the stopper plate.
