Hello all,

 

I have just finished adding 12 gauge common ground and power bus wires around the perimeter of my layou,t. I am now starting to work on my 022 switch wiring.. I want to control them with SPDT toggle switches and use variable voltage plugs. I think I need a total of 4 wires / switch? One wire for the variable voltage plug and fthree wires for the SPDT switch. Obviously the ground will come from my main outer rail. I probably will have 10 or so pairs of switches on my layout. Is there any shortcuts to this? Please advise and if you could include a sketch of how to wire these I would appreciate it much. If it matters I will be running mainly conventional post war with some legacy control.

 

As usual, much thanks Jerry

You can daisy chain the voltage pin. So you don't have to run a separate wire to every switch from the power source, although it would be good practice. The center pin of the switch is also "ground" (outside rail). So you probably can eliminate that wire to the 022 switch and just connect the center pin of the momentary toggle switches to the ground.

You don't need the common, center binding post connection from the switch to the SPDT. Instead, use a common connection near the SPDT switches at the control panel for the center connection of each SPDT, and daisy chain them(you don't have to make home-runs from each DPDT). This will reduce your wiring from about 20 wires(one to each switch) to one.

 

Now, what you can do, is to use each now open center binding post connection and make a connection to your common bus as the bus travels around the layout.

 

For the fixed voltage plugs, if you instead use coaxial barrel plugs, you can make your switch power fixed voltage connections to the tip and your track power connection(s) to the sleeve. This will improve continuity throughout the layout and cut down on obvious power connections like soldering and lockons. You can make similar connections at UCS & RCS binding posts as well.
