Leviton Mfg Co S11-05621-2IS 20A Single Pole Decora Switch

Product Description

The LEVITON MFG CO S11-05621-2IS is a 20-amp single pole Decora-style switch designed for controlling one fixture or load from a single location. Built for residential and light commercial electrical work, it supports tungsten, fluorescent, and resistive load types, making it a versatile choice for general switching applications. The switch includes both Quickwire push-in terminals and side-wiring screws, reducing installation time. Terminal screws accept up to No. 10 copper wire. Sold in a pack of 10 units, this switch is finished in ivory and carries a UL listing along with a limited 10-year warranty. Licensed electricians handle typical installation under NEC guidelines.

This switch suits standard single-location switching in residential construction, light commercial fit-outs, and retrofit projects. Its Decora profile fits any standard Decora or paddle-style wallplate, which is common in modern residential installations. The dual wiring method — push-in Quickwire or screw terminals — accommodates different installer preferences and job-site conditions. Compatible with tungsten (incandescent), fluorescent, and resistive load circuits, it covers the majority of common branch-circuit switching needs encountered by electricians on residential and commercial jobsites.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Always shut off the branch circuit breaker and verify the circuit is de-energized with a voltage tester before wiring. Use either the Quickwire push-in terminals or the side-wiring screw terminals — do not use both methods on the same switch. Ensure the wallbox fill calculations account for device volume per NEC Article 314.
