I'm after the blank / placeholder switch (button?) panels that are found in most cars.. I'm not sure what they're officially called so my Google-foo is completely failing me.
Basically, you will often have a set of 3 - 4 buttons somewhere in your car - for example a switch to turn on the front spotlights, and usually only 1 or 2 of the slots are actually in-use and have switches installed.. the rest are filled with a blank placeholder (presumably for if more switches/whatever are needed later).
So I want to know - a) what the heck are they called? and b) where does one source these?
Any help is greatly appreciated.
