Pass & Seymour 660-G – Frequently Asked Questions

1) Does the Pass & Seymour 660 switch have a ground screw for a metal box?
Yes, it is a grounding-type toggle switch, so the strap carries a ground terminal for bonding the device to the branch circuit equipment ground. That is what current code calls for on replacement and new switch installs, and it is what lets you bond a metal yoke and metal plate properly in an EMT or metal-box commercial installation.
2) Will the 660 Trademaster fit a standard single-gang wall box and a normal toggle plate?
Yes. It is built on standard toggle switch dimensions, 4.195 in by 1.25 in by 1.09 in, which is the usual strap-and-yoke footprint for a single-gang device box and a standard single-toggle wall plate. No oversized plate or deep box is needed for the switch itself.
3) Can I swap a 660 Trademaster in for an old ungrounded toggle switch during a retrofit?
It is a direct fit for standard wall box switch replacements and retrofit work, with one condition: because it is a grounding type device, you need an equipment ground available in the box to land on its ground terminal. In older boxes with no ground conductor, resolve the grounding means first rather than leaving the terminal unused.
4) What is a single-pole alternative to the Pass & Seymour 660 Trademaster toggle switch for a three-way lighting circuit?
The 660 Trademaster is a single-pole grounding toggle switch, so it will not run a pair of switches on one light. For three-way control, the Bryant 4903W is a 3-way AC toggle switch rated 20A 277V in commercial grade, and the Eaton Arrow Hart AH-1223GY is an industrial grade three-way toggle switch rated 20A at 120/277V. Either one lets you control one fixture from two locations; the 660 is the right part only when a single switch controls the load.
5) What spec grade single-pole toggle switch can I use instead of the Pass & Seymour 660 Trademaster on a commercial job that calls for specification grade?
The 660 Trademaster is a grounding toggle switch built in high impact resistant thermoplastic with cULus, CSA and UL listings. If the drawing calls specification grade, the Leviton 1221 is an extra heavy-duty industrial specification grade SPST toggle switch rated 20A at 120/277V, and the Leviton 1221-2KL is an extra heavy-duty spec grade 1-pole toggle rated 20A at 120/277V. Both keep the same single-pole function as the 660 while meeting a spec grade callout.
6) I need a single-pole switch that shows when the load is on - is the Pass & Seymour 660 the right part?
No. The 660 Trademaster is a plain grounding toggle switch with no indicator. For a lighted switch, the Leviton 1201PLC is an industrial grade pilot light toggle switch, 1-pole, 120V, and the Leviton 1221-2L is an industrial grade pilot light toggle rated 120/277V AC, 20A, 1-pole. Both give you the same single-pole switching plus a visible indication, which is common for attic, mechanical room and exterior loads that are out of sight.
7) What colors does the Pass & Seymour 660 Trademaster grounding toggle switch come in?
Two colors: Brown, ordered as 660-G, and Light Almond, ordered as 660-LAG. Both carry a satin surface finish, which holds up better against fingerprints and smudging than a gloss device plate in a corridor or lobby. If you are matching existing devices across a building, the brown is the one that blends with older commercial wiring device layouts and the light almond with newer neutral schemes.
8) Is the 660 Trademaster switch UL listed for commercial work?
It is cULus Listed, and the listing data also records UL Listed and CSA Listed. The cULus mark covers both US and Canadian acceptance, which matters if you are specifying one device across facilities on both sides of the border.
9) Can I use the 660 Trademaster to switch two circuits at once?
No. It is a single-pole device, so it breaks one hot conductor only. Switching two legs together, for example a 240V load or two separate circuits from one handle, calls for a double-pole switch like the Ideal Industries 774005 heavy-duty DPST toggle switch with spade terminals.
10) Will the Ideal 774005 toggle switch work as a substitute for the Pass & Seymour 660 Trademaster in a wall box?
It is not a direct swap. The 660 Trademaster is a single-pole grounding toggle switch sized for standard toggle switch wall box installations with a 1.25 in wide strap. The Ideal 774005 is a heavy-duty DPST on-off toggle switch with spade terminals, so it is a two-pole device intended for equipment and panel-style mounting rather than a decorator or standard wallplate opening. Use it where you are breaking two legs of a circuit on equipment, and stay with the 660 for a standard switch leg in a wall box.
11) What is the closest white single-pole toggle switch to the Pass & Seymour 660 Trademaster, which only comes in brown and light almond?
The 660 Trademaster is offered in Brown (660-G) and Light Almond (660-LAG), both with a satin finish. If the job is standardizing on white devices, the Bryant 4801W is a 4-Series single-pole 15A 277V AC toggle switch in white, and the Leviton 1221-2KL is a white-family extra heavy-duty spec grade 1-pole toggle rated 20A at 120/277V. The Bryant 4801W matches the 660's single-pole function most directly at 15A.
12) What is the body of the 660 Trademaster made of, and will it survive a maintenance crew?
The housing is high impact resistant injection molded thermoplastic, so it resists cracking and chipping from drops and strikes during rough-in and from daily handle use. The satin surface also hides smudging over time, which is the practical difference on a device touched dozens of times a day in a multi-family corridor or classroom.
13) What is the difference between the Pass & Seymour 660 Trademaster and the Bryant 4801W toggle switch?
Both are single-pole toggle switches. The 660 Trademaster is a grounding toggle switch molded from high impact resistant thermoplastic with a satin finish, supplied in Brown and Light Almond. The Bryant 4801W is a 4-Series single-pole toggle rated 15A at 277V AC in white. The practical difference is the finish and color range versus the Bryant's stated 15A 277V AC rating and series identity.
