USES: The MS-3R and MS-4R are 3- and 4-wire versions of the same switch, used for

controlling one screen from multiple locations, using the motor’s voltage (115V or 220V).

MS-4R is the ﬁ rst control station in a series of stations. It is also the intermediate

control (s) in the case of three or more stations. The fourth wire passes electricity to

the next switch in the series. This fourth wire is taped off to create the MS-3R.

MS-3R is the last control station in a series of stations. Therefore, it does not need to

pass electricity to a next switch. It is used with one or more MS-4R controls.

COMPATIBILITY: MS-3R and MS-4R are used with each other as multiple control stations.

They can also be powered on and off with the KS-1 Power Supply Key Switch.

They are not intended for use with any other controls.

CONTACTS: Single-Pole, Triple-Throw (On-On-On). Momentary (spring-loaded) action.

RATING: 16 Amps, 277 Volts, UL recognized, CSA recognized.

DESCRIPTION: Switch is a black, Euro-style (rounded or oval) rocker switch.

Cover plate is aluminum, ﬁ nished silver satin.

MS-3R and MS-4R start out as the same control. The 3 and 4 indicate the number

of wires connected to the switch. The fourth wire is taped off to create the MS-3R.

2¾" x 4½" cover plate ﬁ ts a single-gang box.
