ATX-LED AL-WS-R3 White Low Voltage Switch
The AL-WS-R3 is an on/off decorator-style switch designed for low voltage controls, suitable for 12V, 24V, 48V, and millivolt systems. It supports AWG14 to AWG24 wiring and includes a built-in cleaner function to address corrosion in challenging environments. The shallow body design fits standard junction boxes, and it can be configured for 3-way installations. It is particularly appropriate for replacing aging fireplace switches to restore operation and reliability. Optional break-away wings aid placement near fan switches, with wings removable as needed.
Leviton 3 24 Volt AC/DC Decora Plus Quiet Rocker
This Leviton model supports SPST, SPDT (Center-OFF), and DPDT (Center-OFF) configurations, accommodating common low voltage fireplace control needs. It comes in the most frequently used commercial color options and features heavy-duty construction designed for long service life, backed by a 10-year limited warranty. Its versatility makes it suitable for wiring schemes found in modern fireplace setups where reliability is critical.
ATX-LED AL-WS-R3 Black Low Voltage Switch
This black version provides the same low voltage switching capability as the white variant, with a shallow profile suitable for standard boxes. It includes a built-in cleaning function for corrosive environments and supports an Inrush Current Limiter (ICL) option for electronic loads that may spark when connected. The 1500-volt isolation helps protect sensitive components and users during operation and maintenance. It is an effective option for upgrading fireplace control panels without major rewiring.
TV xStream Fireplace Remote and Voice Switch
This remote/smart switch enables voice control for gas fireplaces with millivolt valves and electronic spark ignition systems. It requires the eWelink app for setup and pairing, and TV xStream offers tech support. It works with compatible smart plugs/outlets, expanding control options beyond traditional wall switches. Note that compatibility depends on the fireplace valve and ignition system, so verify connections before installation.
TV xStream Voice Fireplace Switch (B455)
The B455 model adds voice-enabled control for gas fireplaces, enabling hands-free activation via Google, Alexa, or Siri. It is designed to work with compatible smart outlets and requires pairing with a supported app or ecosystem. Like other smart switches, ensure compatibility with your fireplace’s gas valve and ignition system before installation to avoid operation issues.
Buying Guide: Key Purchase Considerations
- Voltage and compatibility: Ensure the switch supports your fireplace’s control voltage (low voltage, millivolt, or standard line voltage). Some switches target 12V–48V DC/AC, while others are designed for millivolt gas valves.
- Wiring configuration: SPST, SPDT, and DPDT options affect how you wire the switch into your existing control circuit. Plan for 2-wire or 3-way setups as needed.
- Load handling and safety: Look for features like inrush current limiters, high isolation ratings, and corrosion-resistant contact cleaning for environments near fireplaces.
- Installation depth and box fit: Shallow or low-profile designs simplify mounting in standard junction boxes or behind wall plates.
- Reliability and warranties: A long warranty (e.g., 10 years) indicates durability for commercial-grade or residential long-term use.
- Smart features and ecosystem: If considering smart or voice-enabled control, verify compatibility with your smart home ecosystem and whether the fireplace valve supports remote activation safely.
- Safety considerations: For gas fireplaces with millivolt systems, ensure the chosen device correctly interfaces with the valve and ignition and follows local electrical codes.
- Maintenance: Some models include built-in cleaners to counteract corrosion from environmental exposure near fireplaces; consider maintenance needs in damp or dusty areas.
- 3-way and multi-point control: If you need control from multiple locations, select a model supporting 3-way wiring or multi-point configurations.
- Documentation and support: Availability of clear installation guides and developer or manufacturer support minimizes installation risk.
