Or you could just as easily snag one of these nondedicated switch modules that Ladik's got. SIX toggle switches, already drilled and equipped with proper pigtails for connection to most anything. https://www.modulargrid.net/e/ladik-p-060-switches-
But it's got six switches! So, yeah...you can easily use the other five for any "hidden functions" that might be on any of your other modules.
