Reversing Drum Switches

Type A and B

Class 2601 / Refer to Catalog 2510CT9701

NEMA 1, 3R, 4 & 13 Without Overload Protection

Class 2601 reversing drum switches may be used for across-the-line starting and reversing of AC polyphase, AC single phase or DC motors, where overload protection is not required or is provided separately. They are compact and inexpensive but ruggedly constructed. Drum switches are field convertible from maintained only to momentary only operation. This conversion consists of removing the handle screw and handle, turning the shaft 180 degrees, then replacing the handle and handle screw.
Optional handles – All devices offer as standard a one piece handle. An optional ball and shaft or fluted type handle is available. Drum switches with optional handles are available on a factory Quick-Ship basis only. To order, add the letter B or F to the type number, e.g., Class 2601 Type AW2B for a ball and shaft type, Class 2601 Type AW2F for a fluted type. Add $12.70 to the price for a fluted type, no adder for a ball and shaft type. (See photos below.)
