Open question: I have 5121, 5122 switches, powered on track power. Obviously that means the solenoids buzz when a car is sitting on the anti-derail rails. I was playing with one of the worst offenders this afternoon and its a simple fix- just stop the plunger from from vibrating when energized. However- the simple fix renders the switch useless. What I'm looking for is a way to briefly cut the power to the solenoid to limit the length of time it can buzz. I know that these can be re-wired from aux power but that doesn't eliminate the buzzing.
Thoughts?
If you use aux power supplied by a capacitor setup that'll stop the buzz. The Cap has enough energy stored to pull the solenoid plunger and then it runs out of juice until the actuating button is released or the car moves off the derail-rail. Then the capacitor re-charges and is ready to fire again.
