Can I use this switch for a wireless battery-operated doorbell?

Will this fit into my existing square wall box?

Full Product Description

Reliable Momentary Action for Wired Doorbells

This SONLEX Doorbell Switch Panel utilizes a momentary "push-to-make" mechanism, meaning the electrical circuit is only connected while the button is actively being pressed. The moment you release your finger, the internal spring instantly breaks the circuit, making it the exact standard component required to trigger traditional wired household doorbell chimes without burning them out.

Clean Aesthetic with Hidden Screw Design

This 1-Gang Wall Switch is engineered to look flawless on your wall. It includes custom-fit decorative plastic strips that snap securely over the top and bottom edges of the faceplate after installation. This intelligent design completely conceals the ugly metal mounting screws, leaving you with a smooth, uninterrupted white surface that blends perfectly into modern interior designs and freshly painted walls.

Pro Tip from Our Technicians

When installing this Doorbell Push Button, our Sham Shui Po technical team strongly advises turning off the main mains power at your breaker box before handling any bare wires. This switch requires a standard 86x86mm square back box (pattress box) with a minimum depth of 25mm to comfortably accommodate the 30mm deep rear terminal block. If you are replacing an old switch, ensure your existing doorbell chime is a wired model, as this switch cannot trigger wireless battery-operated chimes.
