# Multiswitch complexes

Multiswitch complexes refers to rotaries and buttons/toggles working together to produce more button numbers than the individual switches could do alone. 

There are four variants:

* Hybrid rotary
* Multifunction rotary
* Modded encoder
* Stacked encoder

Comparison:

|                     | Hybrid                                                                                | Multifunction                                         | Modded encoder                                                   | Stacked encoder                                                      |

| *Supported sim*     | Sim needs to accept simultaneous key presses as bindings. Only iRacing comes to mind. | <mark style="background-color:green;">Any</mark>      | <mark style="background-color:green;">Any</mark>                 | <mark style="background-color:green;">Any</mark>                     |

As you can see, they all have their strengths and weaknesses. Visit the subpages to read more about the different multiswitch complexes.&#x20;
