Hello Fellow G Enthusiasts!

Thank you EVERYONE on the forum for their advice! So much has changed in the past 30 years and I feel so ignorant. But thanks to everyone for being kind!

I still use DC track power. Not DCC.

Years ago, I purchased a PH Hobbies sound card with reed switches that I glued on the bottom of my locomotive. As my loco passed a certain spot on my garden railroad where I had a track magnet, the horn would sound.

I have installed another sound card in a different locomotive. I need a USA Reed Switch.jpgsource for the same type of reed switch (with 2 wires) that I can glue on the bottom. Thank You! AJ the Teacher.

Door/window alarm switches are usually closed contacts, for sensors on our trains most sound units need open reed contacts. I prefer the round ones where possible to install vertically, and on LGB engines there is a place in the bottom for short glass reeds to be added inside the motor block and out of sight!!

There are plenty versions of reed switches on Amazon.com. Also GScaleGraphics.com has them.
