I know the Ralliart labeled ones are $150. I had a staff member get chewing gum in the passanger front one and Mitsubishi would only sell him a set of 4.
I have managed to find some switches that fit in there that are toggle switches, but they are from overseas, and are old and rare. And they have cost me about $20 or $30 haha
I can look around for some and give you the ebay links if you like.
But a missile switch or similar is probably your best bet.
