brand new and high quality. Feature: Made of high-quality material, durable, firm and stable for us to use. This kind of DC12-48V wide voltage two-way remote control switch, switch power supply, a professional switching power supply management chip, power supply voltage stability, a complete solution resistance capacity step-down and make the power supply voltage is not stable, lead to the entire switch unstable phenomenon. The remote control switch adopts 30 a relay, can load a high-power electrical appliances, learning microcontroller decoding, can learn more remote control, simple operation supporting flexible. Toggle switch is adopted to improve the switch output work way, dynamic, self-locking, interlocking (point) can be arbitrary choice easy to use, another new way of manual work. Reserved for the output data bits welding plate, can receive through short different solder joint location choice of the remote control buttons, convenient customer supporting various remote control that oneself like, to avoid the old fixed single design keys you can match the embarrassment of the remote control. Mainly used in garage door control, lighting control, electric door, remote control curtains, lifting equipment, motor control, water pump, projection screen elevator control and security industry and other fields. It is easy to install, use the advantages of simple and safe and reliable. Receiver Transmitter only, other accessories demo in the picture is not included!
