Tuya Zigbee Smart Switch Module with Clean Contact for Flush Mount AC and DC
The Tuya Zigbee Smart Flush-Mounted Dry Contact Switch Module is a compact and professional solution designed to manage automations, controls and compatible devices in an intelligent, safe and versatile way. Compatible with AC 100–240V and DC 5–48V power supply, it easily adapts to numerous domestic and professional applications, such as electric locks, automatic gates, intercoms, control relays, lights and low voltage systems . Thanks to the NO/NC/COM dry contact outputs , the module does not supply output voltage but functions as a control relay, making it ideal for smart systems and advanced automations. Available in 1-channel or 2-channel versions, it allows you to control one or two circuits independently, maintaining a tidy and discreet installation behind switches or in flush-mounted boxes. Connected to a compatible Tuya Smart / Smart Life Zigbee gateway , it allows remote control from the app , the creation of timers, scenarios and automations , management of the last state memory and integration with Alexa and Google Assistant for voice control. A smart solution designed for those seeking reliability, flexibility, and complete home automation integration in a mini, built-in format.
Remote control via app with Tuya Smart and Smart Life
Once connected to a compatible Zigbee gateway , the module can be conveniently managed from your smartphone using the Tuya Smart or Smart Life apps. This allows you to turn devices on and off remotely , check their status in real time, and integrate the relay into your home automation systems even when you're not there. A practical feature for managing lights, gates, electric locks, intercoms, and other connected controls more simply, quickly, and intelligently.
Relay Status Memory: Intelligent restart after a blackout
With the Relay State Memory function, you can choose how the module should behave when power returns: ON , OFF , or restore the last state . This is a very useful feature to avoid unwanted switching on or off after a power outage. Furthermore, the command sent from the app and the one given via the physical switch remain synchronized, so the module always maintains the set behavior.
Convenient Voice Control with Alexa and Google Assistant
Universal flush-mounted installation + AC/DC power supply
Mini flush-mounted module for systems and junction boxes, with AC 100–240V (50/60Hz) power supply and low voltage DC support (5V / 12–48V) depending on the model/use.
