Momentary Doorbell vs Standard Light Switch — Don’t Wire the Wrong One

Seven Chroming Finishes — A Doorbell That Matches Your Interior

Chroming Doorbell Push Button — Momentary Bell Push with 7 Metallic Finishes

The TD105 is a chroming doorbell push button that is based on an old notable bell push made in round plastic, making it a full-sized 81.5×120mm wall button. This momentary doorbell push operates with the spring-return method, meaning that pressing the rocker brings the circuit to function and ringing the chime while releasing the rocker returns it back to its original position thus completing the circuit. Unlike a regular latching light switch that remains in position, this doorbell switch connects only while being pressed. Available in seven distinct metallic finishes across White, Black, Gray, and Gold base colors, the TD105 matches the T-D series aesthetic for a uniform wall design from the front door to the living room. Built with high-quality copper and silver contacts, a steel birch plate to maintain its sturdiness, and rated for around 100,000 operation cycles. IEC 60669 certified with a 12-year warranty.

We are a factory-direct manufacturer offering competitive wholesale pricing, OEM branding on any color PC panel, and a 12-year warranty across the T-D series range.

100,000 Cycle Momentary Mechanism — Designed for the Front Entrance

This chromed doorbell features a quality touch-point copper and silver mechanism with a lifetime of 100,000 cycles. Visitors, delivery workers, and other family members push the front-door button several times a day. The 100,000-cycles rating means that this doorbell can last for years while other types of bell push become too sticky after one to two years of use due to mechanical wear. Thanks to the spring return, each press gives a nice tactile response. The steel central plate strengthens the panel, meaning that it will not bend and the rocker’s position will not shift. The front panel made of imported strong-surfaced PC completes the T-D series with its aesthetics. The product is IEDC60669 compliant and features a 12-year warranty from the manufacturer of T-D104 chromed bell switch.

This white PC doorbell with chrome accent is among the items of the T-D series as it has the same dimensions of 81.5×120 mm, and is made of imported PC and comes in seven chrome colors like light switches. The front doorbell can correspond to the light switch at the hallway — same profile, same metallic accent, same color palette. Available in all seven T-D series chroming finishes to ensure a consistent aesthetic from the front door through every room in the house.

Buyer’s Guide

Installing a Chroming Doorbell Push Switch: Wiring, Finishes & Back Box Requirements

A practical guide to specifying and wiring a momentary bell push switch for residential and commercial doorbell circuits.

Momentary vs Latching: Why Does the Difference Matter

A momentary bell button switch ensures that the circuit is completed only when the button is pressed. When released, the connection is broken due to the spring mechanism. This is different from the latching switch that remains clicked in position. Putting any ordinary switch into a doorbell circuit will either cause the doorbell to ring continuously or not at all. The TD105 is a purpose-made momentary switch meant for signaling uses as it has the spring return system, copper and silver contacts, and the rocker configuration for the purpose.

Which Chroming Color to Choose for Your Entrance

White + Chroming Gold: Traditional look — the panel is white with warm metallic borders. Black + Chroming Gun: Minimalist modern look — dark panel with cool gun accents. Gray + Chroming Silver: Minimalist contemporary — the neutral panel with silver accents. Gold + Chroming Gold: Approachable premium look — the panel is gold with the matching frame. The options of pure Black, White, and Gray are also available without chroming.

Installation & Wiring

The TD105 fits the standard 81.5×120 mm back box. For wiring, it is necessary to follow the doorbell wiring schemes: connect two wires from the bell transformer — one to the common terminal and the second one to the chime. There is no need to connect neutral wires in the process. Make sure to switch off the electrical supply before starting installation. In a new installation, one has to run two cable wires from the transformer to the doorbell and to the chime.

Frequently Asked Questions

What is a doorbell push switch?

The doorbell push button is one type of momentary switch that makes an electrical circuit while being pressed. The TD105 is one type of chrome-plated doorbell push button that has a spring-return device. By pressing the button, the chime rings — as soon as it is released, the spring returns the button to its original position, thus breaking the circuit. The button replaces old type circular plastic bell push buttons.

Can I use a standard light switch as a doorbell?

A typical household light switch is a latching type that stays in place after being pressed. Therefore, adding a latching type switch to a doorbell circuit will either make the chime sound permanently or render it inoperative. Instead, to install a doorbell switch, a momentary type switch must be used, like the TD105, which only works when pressed and returns to its original position once released.

Does this doorbell switch require a neutral wire?

No, the TD105 push button push requires no neutral connection. It is a simple two-wire device: one wire from the bell transformer to the common terminal and another wire from L1 to the bell. The circuit is completed only when the button is pressed.

What chroming finishes is this doorbell switch available in?

Seven variants of the TD105 are present in various colors, that is, White, Black, Gray, White + Chroming Gold, Black + Chroming Gun, Gray + Chroming Silver, and Gold + Chroming Gold. The chroming models have metallic framing surrounding the rocker in Gold, Gun, or Silver options; thus, creating a visible design accent, complementing T-D series light switches for consistent wall aesthetics throughout the house.
