This module supports \u003cstrong\u003e2-way wireless control\u003c\/strong\u003e, meaning you can pair two separate RF remotes to the same receiver. This replicates the function of a traditional 2-way or 3-way light switch — ideal for hallways, staircases, or large rooms.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the maximum load this relay can handle?\u003c\/h4\u003e\n\u003cp\u003eA: The relay supports a \u003cstrong\u003emaximum current of 10A\u003c\/strong\u003e at AC 85–240V. This makes it suitable for controlling standard light bulbs, LED strips, and small appliances.
