Each switch group has its own connectors. They come off with a little bit of effort.
The easiest way to get the switches out is to disconnect the connectors, grasp each switch by their short side and squeeze while pushing up. This will enable the switch to pop up from the wood.
People also pry them out from the top, and they will come out, but you have a very high probability of chipping the wood.
The aluminum housing is probably the shifter housing.
