Turnigy receiver controlled switch

[woodhog]

Best I remember the switch has to have the same ground as the receiver ,try that a nd maybe someone else will chime in . I am using these to turn on a motor on my belt drive with no issues. When i first out it in i was using two batteries and once i got the 2 grounds together it worked fine,then later went to a single battery and still works like a charm. Hope this helps
