Micromodule Switch Double enables you to control an in-wall switch or power outlet with zwave certified hub or any Z-Wave remote or module’s built-in push button. This small, hidden Z-Wave module installs in the electrical box behind your switch/outlet, and wires in between your switch/outlet and two connected loads. How it works: When the module is installed behind a twogang wall switch, the wall switches no longer directly control the connected loads. Instead, both switches serve as inputs for the module, which has an internal relay to control the connected loads. This relay transmits commands to your loads from the wall switch or a Z-Wave remote. It supports two loads up to 6A each and has a built-in overload protection.
