they exist!

I 3D printed both 3-way and 4-way switch controllers.

Left, Center and Right buttons have a micro-spst under each button head. The SPST button switches go to a circuit that controls the three DZ2500C switch machines on the three-way Ross turnouts. The 3-way circuit requires 4 diodes that switch the specific set of DZ2500C machines to align with the direction desired.

The 4-way is like the 3-way with an additional button. Here you are controlling 4 switch machines that are synched for the 4 directions.
