Eaton AHCS420LA-BU Toggle Switch 4-way 20 Amp

Product Description

The EATON AHCS420LA-BU is a 4-way toggle switch rated for 20 amps, designed for residential and light commercial electrical wiring applications. It enables multi-location switching control of a single load, such as a light fixture or switched outlet, when wired in combination with two 3-way switches at each end of the circuit. Rated at 20 amps, it provides greater current capacity than standard 15-amp toggle switches, making it suitable for circuits serving higher-draw lighting loads. Licensed electricians typically specify this switch when an installation requires three or more control points on a single circuit.

This 4-way toggle switch fits standard single-gang wall boxes and works within conventional multi-location switch wiring schemes. It is commonly installed in residential corridors, stairwells, large rooms with multiple entry points, and commercial spaces where code requires switching from three or more locations. The switch is appropriate for new construction and retrofit wiring projects and is installed by licensed electricians following NEC guidelines for branch circuit wiring.

Key Features

• 4-way switching function enables multi-location control from three or more switch positions
• 20-amp rating supports higher-capacity branch circuits compared to standard 15-amp devices
• Toggle-style actuator for reliable, tactile switching operation
• Standard single-gang form factor fits common wallplate and electrical box configurations

Compatibility

Designed as an OEM-style replacement or new-installation 4-way toggle switch for use in standard residential and light commercial branch circuit wiring applications.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the circuit at the breaker panel and verify absence of voltage with a meter before wiring. A 4-way switch must be wired between two 3-way switches in the circuit and cannot function as a stand-alone switch or replace a 3-way device. Verify the box fill and conductor ampacity are appropriate for a 20-amp circuit before completing the installation.
