Fixing Turnout Switch Failures
Ed who models HO scale asks readers:
“I am having problems with the switches pressed to actuate a turnout. I’m finding them staying stuck in the depressed condition causing the turnout motor to melt. Does anyone else see this problem. Its happened to me enough times to get expensive.”
SUBMIT YOUR QUESTION
Firstly I would fit a simple on/off kill switch between your power source and the points so if you notice a problem you can cut the power before any damage occurs. Secondly I would use a passing contact switch such as the Hornby Railways R044 that doesn’t rely on a spring to reset. It only activates the point motor when you move the lever.
a tiny spray with wd40 or kontakt60 works wonders in situations like these…..
