Pass & Seymour PS-15AC1L Extra Heavy-Duty Specification Grade Lock Switch, 20A 120/277V

The Pass & Seymour PS-15AC1L Extra Heavy-Duty Specification Grade Lock Switch is a 1-pole locking toggle switch rated 20A at 120/277V, engineered for demanding industrial and commercial installations. It features back and side-wire external screw-pressure-plate terminals that accept #14 - #10 AWG copper or copper-clad conductors, along with a cULus Listed rating for code-compliant performance where reliability under heavy use is critical. This lock switch is available in Gray, Ivory, and White to match a range of finish schemes, with every color option built to the same specification-grade electrical rating and construction standard described below.

Key Features

  • Locking Design: Locking support provides resistance to face and back body separation for secure, tamper-resistant operation.
  • Durable Construction: Back body made of glass-reinforced nylon and a high-strength thermoplastic polycarbonate toggle for long-term durability.
  • Wiring Method: External screw-pressure-plate back and side-wire terminals accept #14 - #10 AWG copper or copper-clad conductors.
  • Electrical Rating: 1-Pole, 20A, 120/277V rating suited for extra heavy-duty specification-grade applications.
  • Fast, Positive Switching: Cam controls a fast make and positive break to minimize arcing, with heavy-gauge one-piece copper alloy contact arm to virtually eliminate contact bounce.
  • Quiet Operation: Heavy-duty bumper pads reduce noise during switching.
  • Grounding: Nickel-plated steel strap with integral ground, auto-ground clip, and standard grounding terminal assure positive ground.
  • Contacts: Oversized silver alloy contacts for long life and better heat dissipation.
  • Finish: Matte finish with a shallow design for ease of installation, available in Gray, Ivory, or White.

Pass & Seymour PS15AC1-L – Frequently Asked Questions

1) Will the Pass & Seymour PS-15AC1L lock switch work on a 277V lighting circuit?
Yes. The PS-15AC1L is rated 20A at 120/277V, so it can be used on 277V commercial lighting branch circuits as well as standard 120V circuits. It is a single-pole locking toggle, so it handles one switch leg per device.
2) What wire size can I land on this locking toggle switch, and can I back-wire it?
The terminals are external screw-pressure-plate type, back and side wire, and accept #14 through #10 AWG copper or copper-clad conductors. That means you can feed the conductors straight into the back for a cleaner box fill on a multi-gang run, or wrap them on the side screws if that suits the box better. It also has a nickel-plated steel strap with integral ground, an auto-ground clip, and a standard grounding terminal.
3) What makes a lock switch different from a regular commercial toggle switch, and when should I use one?
A lock switch is built so the face resists separating from the back body, which makes it tamper-resistant in the device box. Use it where you do not want the switch pulled apart or interfered with: industrial plants, equipment control circuits, mechanical rooms, and public or tenant areas where a standard specification-grade toggle gets abused. Electrically it does the same job as a 20A single-pole commercial toggle. If tampering is not a concern, a standard spec-grade 20A toggle is the simpler choice.
4) What colors does the PS-15AC1L lock switch come in, and will it match my existing device plates?
Three colors: Gray (PS15AC1-L), White (PS20AC1-WL), and Ivory (PS20AC3-IL). All three are the same 20A 120/277V specification-grade device with a matte finish, so you can standardize electrically across a building and still match the plate color on each area.
5) Is this switch durable enough for a high-traffic industrial panel or equipment room?
It is built as an extra heavy-duty specification grade device: glass-reinforced nylon back body, a high-strength thermoplastic polycarbonate toggle, a heavy-gauge one-piece copper alloy contact arm that limits contact bounce, and oversized silver alloy contacts for longer life and better heat dissipation. A cam gives a fast make and positive break to cut arcing, and heavy-duty bumper pads keep the switching noise down.
6) Does this lock switch fit a standard shallow device box?
The body uses a shallow design specifically to ease installation in tight boxes, which helps when you are adding a spec-grade device to an existing shallow or crowded gang box. Back wiring also keeps the conductor bends shorter than side wiring.
7) How is the PS-15AC1L lock switch packaged for a bulk order?
It ships in packs of 10 each, which suits multi-device rough-in or a facility-wide switch standardization. Country of origin is Mexico.
