What size toggle switches on Panel?

Just make sure they have adequate current capacity, since they have to break the current demands of a short circuit.  I have about 70 minis controlling blocks, and have had no problems over the last 20 years.

We used mini's. There is a video with some explanations in my YouTube channel.

My "block control" panel uses miniature toggles and #22 gauge wire since they are used with a separate relay panel that actually controls block power to the track.  The relays are rated at 15 amps and are wired to the track using #16 gauge wire.

 

This panel is used along with an MTH DCS AIU control unit that is also used for block control.

 

My DCS TIU/AIU wiring boards are also shown. All wiring to the AIU terminals is also #22 gauge.

 

 

I also have a Dispatcher Panel that has colored LEDs which show the status of all turnouts and blocks. Red and green LEDs are for turnout position and yellow LEDs are for block power status. All wiring to this panel is #22 gauge.

     I use SPST, from Radio Shack. Do not know the ratings. I use them to set up blocks for all the main lines and sidings. I only have to use these when I run traditional engines.

The miniature toggle switches that I have seen are rated for 5 amps or less, the standard toggles switches are generally rated for 10 Amps or more based on the switch construction. I am using the miniature toggle switches for tortouse switch motors and standard toggle switches for track connections.

I found a great deal on EBAY and ordered 25 toggle switches like you see in the photo, all of them DPST type.

I have several DPDT center off toggles most have wires soldered on but can easily be removed. I used them for block control for two transformers.  $1.50 each plus shipping
