Pass & Seymour 663-G – Frequently Asked Questions

1) Will the Pass & Seymour 663 switch fit a standard device box and wallplate?
Yes. The 663 Trademaster measures roughly 4.195 in. high, 1.25 in. wide and 1.09 in. deep, which is the standard toggle device footprint for single-gang boxes and standard toggle wallplates. The strap height covers both plaster ears and standard box screw spacing, so no special plate is needed.
2) Does the 663 Trademaster switch have a ground terminal?
It does. The 663 is the grounding version of the Trademaster toggle, so it includes a grounding provision on the strap for connecting the equipment ground. That matters in metal and nonmetallic boxes where the device must be bonded, which is the usual requirement on commercial work.
3) Is the Trademaster 663 a residential-grade switch or can I use it in a commercial building?
The 663 is built for both residential lighting and circuit control and commercial electrical installations, including new construction and retrofit wiring. If your spec calls specifically for industrial or extra heavy-duty specification grade, that is a different class of device, for example the Leviton 1221 extra heavy-duty industrial specification grade toggle.
4) I need a three-way switch instead of a single-pole - what should I order?
The Pass & Seymour 663 Trademaster is a single-pole grounding toggle switch, so it will not control a light from two locations. For three-way control, the Bryant 4903W is a 3-way AC toggle switch rated 20A at 277V in commercial grade, and the Eaton Arrow Hart AH-1223GY is an industrial grade three-way toggle switch rated 20A at 120/277V. Three-way switches need a traveler conductor at each box, so confirm the existing wiring before swapping.
5) What is a specification grade alternative to the Pass & Seymour 663 toggle switch for a high-traffic commercial corridor?
The Pass & Seymour 663 Trademaster is a thermoplastic grounding toggle switch offered in brown, light almond, and white. For a heavier duty device, 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 switch rated 20A at 120/277V. Both are single-pole switches like the 663, so the wiring at the box is the same.
6) Is the Ideal 774005 toggle switch a substitute for the Pass & Seymour 663?
No. The Ideal Industries 774005 is a heavy-duty DPST on-off toggle switch with spade terminals, which makes it an equipment and appliance style switch rather than a wall device. The Pass & Seymour 663 Trademaster is a grounding toggle switch sized for standard device boxes and wallplates at roughly 4.195 in. high by 1.25 in. wide by 1.09 in. deep. For a wallbox replacement, stay with the 663 or another single-pole wall switch.
7) What colors does the Pass & Seymour 663 Trademaster grounding toggle switch come in?
Three colors: brown (663-G), light almond (663-LAG), and white (663-WG). All three share the same thermoplastic body with a satin surface, so a mixed-color job stays consistent in texture and gloss. For property managers standardizing a building, the catalog number only changes by the color suffix.
8) Will the 663 Trademaster work for switching a two-pole motor or equipment circuit?
Not the right tool. The 663 is a standard grounding toggle for lighting and general circuit control, not a double-pole device. For a two-pole on-off disconnect use something like the Ideal Industries 774005 heavy-duty DPST toggle switch with spade terminals.
9) Which switch should I use if I want a lighted switch so staff can see it in a dark mechanical room?
The Pass & Seymour 663 Trademaster is a standard grounding toggle switch with no indicator. If you want an illuminated indicator, 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 switch rated 20A at 120/277V AC, 1-pole. Both are single-pole devices, so they drop into the same position as the 663.
10) Where is the Pass & Seymour 663 switch made, and is there a spec sheet for submittals?
Country of origin is China. Pass & Seymour publishes a separate spec sheet for each color version, 663G, 663LAG and 663WG, which is what to attach when a GC or owner asks for product data on the switch package.
