Leviton M1221-E – Frequently Asked Questions

1) Is the Leviton M1221-E sold individually or only in bulk?
The M1221-E single-pole toggle switch comes as a 100-unit pack. That quantity suits a contractor rough-in or an MRO stock order where the same switch is going into dozens of openings; if you only need a handful for a service call, a bulk carton is more than you want to carry.
2) Can I use a 20A single-pole toggle switch like the Leviton M1221-E on a 15A lighting circuit?
Yes. The M1221-E is rated 20A, and a switch rated above the circuit ampacity is fine, so it works on 15A branch circuits as well as 20A ones. The reverse is not true: a 15A switch should not be used to control a 20A circuit. Standardizing on the 20A device across a building avoids having to track which switch went where.
3) What does single-pole mean on the Leviton M1221-E, and will it work for a switch loop with two switch locations?
Single-pole means one switching location controlling the load, straight on/off. It will not work where two separate wall boxes need to control the same light. For that you need a three-way device, such as the Bryant 4903W 3-way toggle switch or the Eaton Arrow Hart industrial grade three-way toggle. Pick the three-way for stairwells, long corridors, and rooms with two entrances.
4) What is an equivalent to the Leviton M1221-E if I need a 20A single-pole toggle switch from another brand?
The Leviton M1221-E is a 20A single-pole toggle switch. Comparable single-pole 20A toggle switches include the Pass & Seymour CS20AC3I, a commercial 20A specification grade toggle switch in ivory, and the Pass & Seymour PS20AC3W, an industrial extra heavy duty specification grade toggle switch in white. Both are specification grade devices, so match the color and grade to what the rest of the facility already uses.
5) I need three-way switching, not single-pole - what should I order instead of the M1221-E?
The M1221-E is a single-pole switch, so it controls a load from one location only. For two switching locations, use a three-way device such as the Eaton Arrow Hart industrial grade three-way toggle switch, rated 20A at 120/277V, or the Bryant 4903W three-way AC toggle switch rated 20A 277V in commercial grade. Both carry the same 20A rating as the M1221-E while adding the traveler terminal a three-way circuit requires.
6) Is the Bryant 4801W a direct substitute for the Leviton M1221-E?
Not on the amperage. The Leviton M1221-E is rated 20A, while the Bryant 4801W 4-Series single-pole toggle switch is rated 15A at 277V AC. Both are single-pole toggles, but on a circuit specified for a 20A device the 4801W is not an equal replacement. For a 20A single-pole swap, look to the Pass & Seymour CS20AC3I or PS20AC3W instead.
7) Is the Leviton M1221-E a residential-grade switch or is it suitable for a commercial building?
It is built for commercial and industrial lighting and general-purpose circuits, not residential duty. The 20A rating is the dividing line in practice: residential-grade devices are typically 15A and fall short on higher-load circuits. If you want a different brand in the same class, the Pass and Seymour CS20AC3I is a commercial 20A specification grade toggle, and the PS20AC3W is an industrial extra heavy duty specification grade version.
8) What is the exact part number to order for the Leviton 20A single-pole toggle switch?
Order Leviton M1221-E. That is the manufacturer part number, a single-pole 20A toggle switch supplied 100 to a pack. Distributors quoting against a drawing should match on the full suffix, since Leviton toggle numbers differ by pole configuration and packaging.
9) Does the Leviton M1221-E come with wall plates?
No. The M1221-E is the switching device only, so wall plates and any required box or mounting screws beyond what ships on the device have to be ordered separately. On a 100-piece rollout that means a matching count of plates on the same order, or you finish the rough-in and stop short of trim-out.
10) I am replacing an old Pass & Seymour 660 Trademaster switch - can I use the Leviton M1221-E?
The Pass & Seymour 660 is a Trademaster grounding toggle switch, and the Leviton M1221-E is a single-pole 20A toggle switch, so confirm the existing circuit's pole configuration and load before swapping. Where the opening is a straight single-location on/off on a 20A circuit, the M1221-E covers it, and it ships in packs of 100 for crews re-devicing a whole floor. If you want to stay within Pass & Seymour, the CS20AC3I is a 20A specification grade single-pole toggle.
