Hi @Anonymous ,
Would you like to filter the gallery by toggle values which are SP list choice column values?
If so, I made a test on my end. Please see below gif and check if it is what you want:

Steps as follows:
1\ Set OnCheck of each Toggle, eg. Chiller Toggle:
Collect(colClass,"Chiller")
2\ Set OnUncheck of each Toggle, eg. Chiller Toggle:
RemoveIf(colClass,Value = "Chiller")
3\ Items of the Gallery:
Filter(Filter(YourSPlist,If(Toggle2.Value,true,'Unit Class'.Value in colClass.Value)),StartsWith(Title,SearchBar.Text))
Hope this helps.
