Pipe Organ Console: Piston caps for momentary switches

For those who want to build a virtual organ

This is set of 21 caps that can be attached to a top of a momentary push button with diameter of 13mm. There is one blank caps and caps with numbers from 1 to 20.

What even are pistons?

Pistons allow organist to change sound of the entire organ by a press of a single buton, each piston sets a combination of stops (sets of different sounding pipes) so that various arrangements can be played without pulling in and out many stops manually.

Where and how to use this project?

This project can be used for both classical and theatre organs. If you don't know how to control the registration of your virtual organ, you can check my project of circuit board designed for scanning array of tabs and pistons and sending MIDI signal to the MidiTizer: Electronics for controlling a virtual organ.

You can friction fit them although I suggest gluing them for the long term. I was able to buy 20 buttons for this project for $10. Enjoy, SP6GK
