Smart DC 10A Basic Switch | 8-40VDC, Dry Contact | Tuya Smart Life

A Smart DC 10A Basic Switch is a versatile low-voltage controller that integrates non-smart DC devices or circuits into a smart home ecosystem. Unlike standard smart switches that output the same voltage they are powered by, a dry contact version acts as a secondary, isolated relay.

How does the dry contact work?

Think of the device as having two distinct "sides":

• The power side: connected to a constant power source.
• The contact side: two terminals that are labeled as COM and NO (normally open) act exactly like a manual wall switch.

Product features

• Dry contact relay: the switching mechanism is isolated from the device's internal power supply. This allows you to switch different voltages or simply "close a loop" without introducing any new current into the target circuit.
• Scheduling and timers: set automated routines to run high-energy devices during off-peak hours to save on electricity costs.
• Voice control: integration with assistants like Amazon Alexa or Google Assistant for hands-free operation.

Specifications

• Model: WL-SW01
• Input voltage: 8~40VDC
• Output current: <10A
• Wireless protocol: WiFi (2.4GHz) and Bluetooth

Typical applications (not limited to)

• Gate and garage door openers: most gate motors use a 'pulse signal' to trigger movement. A dry contact can safely bridge the motor's trigger terminals without sending high-voltage AC into the control board.
• Boiler and HVAC control: many heating systems use low-voltage "call-for-heat" loops.
• Intercom integration: it can be used to "press" the electronic release button on an existing intercom system remotely.
• Inching/momentary mode: support "inching," where the switch closes for 0.5 to 1 second and then automatically opens, mimicking a physical button press.
