Nigel Heather Posted February 5, 2023 Share Posted February 5, 2023 Hi, Looking for products, circuit diagrams or ideas for a switch (a relay, a transistor etc) that I can switch on and off from a receiver channel. For example, I have a plane that has LED lights in the wings - the kit just plugs them into the supply on a receiver channel which means that they are always on. Thinking it would be nice to be able to switch them on and off using a transmitter switch via a receiver channel. Interested to hear any ideas and suggestions.

Brian Sweeting 1 Posted February 5, 2023 Share Posted February 5, 2023 Try "RC receiver switch" on ebay, lots out there. 1 Quote Link to comment Share on other sites More sharing options...

John Lee Posted February 5, 2023 Share Posted February 5, 2023 I've successfully used a couple of Dr Mad Thrust electronic on/off switches and also the Strobon dedicated LED controller. 1 Quote Link to comment Share on other sites More sharing options...

GrumpyGnome Posted February 5, 2023 Share Posted February 5, 2023 Surely operating lights is just like operating, for example, a retract - one position is 'off', another is 'on'. No need for any additional electronics....... Quote Link to comment Share on other sites More sharing options...

No what he is wanting is a power switch which is operated from the receiver, the receiver outputs a position signal which a retract controller senses as up or down. As others have said plenty of switches out there and there are also a few LED units that do have radio controlled LED light options, I have one that can use a 3 position switch to have all LEDs off, Navigation LEDs on and Navigation and landing LEDs on. BTW Model Radio Workshop also does a range of electronic switches. Quote Link to comment Share on other sites More sharing options...
Outrunner Posted February 5, 2023 Share Posted February 5, 2023 I've made a LED switch before using an old servo board. I can't remember exactly how but do a web search and you should find a guide, it was quite simple just using the servo board and getting rid of the motor and gears. 1 Quote Link to comment Share on other sites More sharing options...

No need for any additional electronics....... The output from the receiver is a series of pulses the width of each being determined by the input position. A servo has electronics which converts the pulse width to an analogue value which is used to determine the servo position. True I only want an on/off but that still relates to pulse with narrowest width and pulse with widest width - I still need some electronics to turn that into Low and High values which can be used to switch an LED on and off. As others have pointed out, there are plenty of cheap options that already exit. Interesting idea about using an old servo board though, hadn’t thought of that and would have given that a go had I not already ordered a product.
