Pass & Seymour PS20AC2 Extra Heavy-Duty Spec Grade Toggle Switch, Brown

The Pass & Seymour PS20AC2 is an Industrial Extra Heavy Duty Specification Grade toggle switch finished in Brown, engineered for demanding commercial and industrial wiring applications. It features external screw-pressure-plate back and side wiring that accepts #14 - #10 AWG copper or copper-clad conductors, a standard grounding terminal, and an auto-ground clip that assures a positive ground connection. Backed by a cULus Listing, this spec grade switch combines a cam-driven mechanism with oversized silver alloy contacts to deliver long-life, dependable switching performance for professional electrical installations.

Key Features

  • Wiring Range: External screw-pressure-plate back and side wired terminals accept #14 - #10 AWG copper or copper-clad conductors.
  • Auto-Ground Clip: Assures a positive ground connection for reliable, code-compliant grounding.
  • Cam-Controlled Switching: Delivers a fast "make" and positive "break" action to minimize arcing during operation.
  • Heavy-Gauge Contact Arm: One-piece copper alloy contact arm virtually eliminates contact bounce for smoother switching.
  • Oversized Silver Alloy Contacts: Provide long contact life and improved heat dissipation under heavy use.
  • Durable Construction: High-strength thermoplastic polycarbonate toggle and a glass-reinforced nylon back body resist wear in demanding environments.
  • Nickel-Plated Steel Strap: Integral ground strap adds durability and a secure mounting platform.
  • Locking Support & Shallow Design: Locking support resists face-and-back body separation, while the shallow design eases installation; heavy-duty bumper pads keep operation quiet.

Pass & Seymour PS20AC2 – Frequently Asked Questions

1) What wire gauge does the Pass & Seymour PS20AC2 switch accept, and can I back-wire it?
The PS20AC2 takes #14 through #10 AWG copper or copper-clad conductors on external screw pressure-plate terminals, and those terminals are both back and side wired. So you can run the conductors straight in the back of the device or wrap them on the side screws, whichever suits the box. No push-in stab holes here, everything clamps under a pressure plate.
2) Does the PS20AC2 toggle switch ground without a pigtail to the box?
It has a standard grounding terminal plus an auto-ground clip, so the nickel-plated steel mounting strap makes a positive ground to a grounded metal box through the mounting screws. You still have the green terminal available if your inspector or spec wants a bonding conductor landed directly on the device, which is the usual call in a non-metallic box.
3) Can I use a Bussmann TPHCS-250 in place of a Pass & Seymour PS20AC2?
No - they are not interchangeable. The PS20AC2 is a wall-box toggle switch for AC branch circuit and lighting control, cULus Listed, with screw-pressure-plate back and side wiring for #14 to #10 AWG conductors. The Bussmann TPHCS-250 is a TPH Series high-current switch rated 80 Vdc with 100kA SCCR, which is a DC power switching device rather than a device-box toggle. If the application is line-voltage AC lighting or receptacle control, stay with the PS20AC2 or another AC snap switch.
4) What is a comparable heavy-duty AC toggle switch to the Pass & Seymour PS20AC2 if I need a pilot or lighted toggle?
The PS20AC2 is a spec grade brown toggle switch with back and side wiring for #14 to #10 AWG copper or copper-clad conductors and an auto-ground clip, but it is a plain toggle with no illumination. Where the opening calls for a lighted toggle so the switch can be found in a dark corridor or mechanical room, the Bryant 4801GLI is a 4-Series 20A 277V lighted AC switch. Both are AC snap switches for commercial branch circuit control; the difference is the illuminated toggle on the Bryant.
5) I need to keep tenants from shutting off a circuit - is there a lockable alternative to the Pass & Seymour PS20AC2?
The PS20AC2 is a standard toggle with no provision for locking the handle in position. For equipment circuits, exterior lighting, or shared spaces where the toggle must stay where the electrician left it, the Bryant 4802L is a 4 Series single-pole locking AC switch rated 20A 277V. Use the PS20AC2 for general spec grade switching and the locking 4802L where the handle needs to be secured.
6) Will the PS20AC2 fit in a shallow existing switch box during a retrofit?
Shallow depth is one of its design points, which helps when you are pulling an old device out of a cramped or shallow-set box with several conductors already in it. The device body measures 3.281 inches high, 1.32 inches wide, and 1.073 inches deep. Locking support construction keeps the face and back body from separating while you are working the wires back into the box.
7) Will this brown switch match the other devices in my building?
The PS20AC2 is brown with a matte finish, which matches the older brown device trim common in commercial and multi-family buildings built before ivory and white became the default. If your other openings are ivory, white, gray, or black, this one will stand out in the gang, so match the existing wall plates and adjacent receptacles before you standardize on it.
8) I need a lighted or a locking toggle switch instead of a plain one. What else is there?
The PS20AC2 is a plain toggle with no pilot light and no key or lock feature. If you need the handle illuminated so staff can find it in a dark corridor, the Bryant 4801GLI is a lighted AC switch in the 4-Series. If you need to keep tenants or students from operating it, the Bryant 4802L is a single-pole locking AC switch in the same 4 Series. Both are different device functions, not finishes, so pick on function first and then match the plate.
9) What is a lighter-duty alternative to the Pass & Seymour PS20AC2 for a 15A lighting circuit?
The PS20AC2 is built as an industrial extra heavy duty specification grade device, with oversized silver alloy contacts, a one-piece copper alloy contact arm, and a glass-reinforced nylon back body. If the circuit is a 15A branch and that level of construction is more than the job needs, the Bryant 9801 is a BR Series 1-pole 15A 120/277V AC switch. Match the device rating to the overcurrent protection on the circuit when choosing between them.
10) How do I choose between the Pass & Seymour PS20AC2 and the Bryant CSB2BW for a 277V commercial job?
The PS20AC2 is a brown spec grade toggle with a matte finish, an auto-ground clip, a nickel-plated steel strap, and cam-controlled switching for fast make and positive break. The Bryant CSB2BW is a DPA Series 1/277V wiring device switch. Both are commercial AC switching devices; select on the toggle style, finish, and wiring terminations your standard calls for, and keep one series across a facility so replacements stay consistent.
11) Why does the PS20AC2 use a cam mechanism and silver alloy contacts instead of a plain toggle?
The cam drive gives a fast make and a positive break, which cuts the arc time at the contacts, and the oversized silver alloy contacts spread the heat and last longer under repeated switching. The one-piece copper alloy contact arm cuts contact bounce. That combination is what separates a spec grade switch from a residential one on a circuit that gets switched dozens of times a day, such as corridor or shop lighting.
12) Where is the Pass & Seymour PS20AC2 made, and what is the exact part number to order?
Order it as Pass & Seymour PS20AC2. It is manufactured in Mexico. That single part number covers the brown extra heavy duty spec grade toggle switch, so there is no separate suffix to specify for color or wiring style, back and side wiring are both built into the same device.
13) Does the PS20AC2 switch come with a wall plate?
No plate is part of the device. The PS20AC2 is the switch only, with its nickel-plated steel strap and mounting screws serving as the mounting platform, so order the wall plate separately and in a finish that matches the brown body if you want them to agree.
