jimbob Posted July 8, 2020 Share Posted July 8, 2020 As you will know when it comes to anything electrical l an a bit of a dumbo. So l have some magnetic reed switches that l wish to fit to my battery powered locos so l can isolate the battery when not in use rather than keep taking the battery out. I have tried this on one but l can't get it to work. I assume l just attach the wires to either end of the switch and pass a magnet over it to open and close the circit but zilch happens. Now when you all stop laughing can anyone point out where the village idot has gone wrong please. Link to comment Share on other sites More sharing options...
traingeekboy Posted July 10, 2020 Share Posted July 10, 2020 Is the reed switch designed to be off until a magnet passes near it, or is it designed to be on? Try taking a 9 volt battery and a simple light bulb and making a small circuit like so: battery > light bulb > reed switch > back to battery What happens when your apply the magnet? It should solve your problem for you. Link to comment Share on other sites More sharing options...
Stese Posted July 12, 2020 Share Posted July 12, 2020 Hi Jimbob, Are you able to provide a link to the part you are using? Regards, Steve D. Link to comment Share on other sites More sharing options...
Coast West Posted August 8, 2020 Share Posted August 8, 2020 you mention that you “pass” the magnet over. Do you take it away ? The reed switch only operates when the magnet is near it, it doesn’t latch (stay in position). you’ll need a circuit / different component otherwise. As Steve said a link to the part would help.
