The 8-bit switch is a device that can enable or disable the output, similar to the 1-bit switch. It has a 1 byte input, 1 byte output, and a bit toggle switch. When the bit toggle switch is 1 or 
, it outputs the input. When the bit toggle is 0 or 
, the output is disabled. Because the output is fully disabled, this mean you can connect multiple outputs onto the same wire without causing a short circuit, provided that at most 1 distinct value is output.
TODO: Clarify. with some examples.
Switches (or disabled outputs of any kind) do not help with circular dependencies.
