Digikey has 32,000 in stock and your search filters yielded 100’s of nearly identical components from different manufacturers. This could mean using 4 pole switches when you only need 3 because toggles are typically 1,2, or 4 pole.

- tear down a mass produced product that has approximately the right size of part that you're looking for and see what you can find. If you're super lucky there'll be a generic part number on the item that you can use to do some research with. If you're less lucky, take some measurements (dimensions, RPM, torque, voltage, current, wavelength, whatever) and start looking around to see if there are manufacturers making generic versions of that part.
