Most of the systems in an aircraft cockpit are controlled with toggle switches and push-buttons. With SimVimCockpit you can configure as many switches as you need.
When making cockpit controls you should know what type of switches you need to control every function in your cockpit - toggle switch with maintained functions (OFF-ON), toggle switch with one or two momentary positions, push-button switch with either momentary or alternate functions.
For more information about the different types of switches, see the tech guide pages.
To work with SimVimCockpit correctly, the throw terminals of every toggle switch or push-button should be connected to one Arduino pin or one extended input directly, without using any pull-up/pull-down resistors. Another, "pole" terminal is connected to the common GND bus:
You can group a set of switches into one module/panel using multiplexer extension boards. Place several modules in different parts of your cockpit and connect them to the main board using only one pin for each multiplexer and a 4-wire address bus (or 6 wires if +5 and GND are included) that are laid across the cockpit to each multiplexer:
