I have 2 of these - https://railsofsheffield.com/products/rails-connect-rpm-smd-1-rails-connect-high-efficiency-surface-mount-digital-point-motor-single-pack connected to 2 x Peco points with both decoders set with the same accessory number as I need to switch them both at the same time, this works correctly as expected. At the weekend I added a single momentary switch so that i can manually switch them by just pressing the switch. This works for a few seconds and then point A switches back after approx. 5 seconds and then point B switches approx. 10-15 seconds later without me doing anything! I have double checked all the wiring but cannot find anything obviously wrong. It's as if the DCC accessory decoder setting is somehow overriding the manual switch setting. If I change the switch to control just 1 point it works as expected so perhaps I just need to have 2 switches? Alternatively maybe I should just use 1 decoder for both point motors but as they are 4 metres apart i'm not sure if this is too far or maybe it doesn't matter providing you're using DCC solenoid connection wire DCW-PW25 ? My final question is should the points have their springs removed or not when using these decoders or doesn't it matter? I currently have 1 with and 1 without. thanks for any help/suggestions.
