This item is a wireless RF remote control and receiver kit, primarily used to control devices like DC  linear actuators, or other DC-powered applications. 

The kit components include:

• A two-button white remote control: It features simple geometric icons (triangle, square and an inverted triangle) for basic functions, like up, down and stop.
• A white control module/receiver: This unit processes the RF signals from the remote and has multiple wired connections (typically 1x  input and 2 x output power jacks) to integrate with a power source and  target devices.
