CLASS 2601 REVERSING DRUM SWITCHES
Reversing drum switches are designed to start and reverse motors by connecting them directly across-
the-line. The devices may be used with squirrel cage motors; single-phase motors designed for
reversing service; and series, shunt, and compound DC motors. The applications should be such that
across-the-line starting of the motors is not objectionable, unless other means is provided for limiting
starting current and torque. Class 2601 drum switches are field convertible from maintained to
momentary operation.
Application Data
The reversing drum switches find application wherever manual reversing control is desired. They are
particularly suited for use on machine tools, woodworking machines, and similar types of equipment.
Examples include lathes, milling machines, planers, grinders, shapers, and boring mills. Other possible
applications include door operators, small hoists, and conveyor belts.
Overload and low voltage protection are not incorporated in these reversing drum switches. Should the
power fail, the contacts will remain closed, unless assembled for momentary operation, and the handle
stays in the selected position. The motor will restart when the power returns.

operating shaft. They are fully insulated from each other and from the
shaft. Stationary contact fingers are mounted in polymeric blocks. Both
movable and stationary contacts are plated for maximum life. Extremely
accessible terminals are provided for easy wiring. Type A is provided
with screw type terminals and Type B is provided with pressure wire
connector terminals. Contacts are not replaceable.
maintained position operation. That is, when the handle is moved to the
forward or reverse position, it will remain there until moved. The
mechanism can be easily converted, with no additional parts needed,
to provide “spring return to off” operation. This conversion is
accomplished by removing the handle screw and handle, turning the
shaft 180 degrees, and then replacing the handle and handle screw.

type handle) or F (for fluted type handle) to the type number.
applications when normal atmospheric conditions prevail. The NEMA
Type 4 enclosure is suitable for applications requiring watertight and
dusttight capabilities. Generous wiring space is provided in both types.
Two knockouts or openings for 1/2” conduit entries are located in the
bottom plate of the AG/BG types, while two 1/2” conduit entries with
hubs are provided as standard in AW/BW types.
A single captive screw holds the cover on NEMA Type 1 enclosures,
while three captive screws hold the cover on NEMA Type 4 enclosures.
Removal of the cover allows free access to three sides of the switch
mechanism. Large legible nameplates are securely attached to the
enclosures to clearly indicate switching positions and to provide
complete rating information. An instruction sheet showing motor
connections is also provided.
Large movable contact segments are rigidly attached to the main
