I found a good source for replacing the awful blue illuminated switches on the control panels found in the newer units. I did not like the bright blue glow at night. I found the red version of the switch if anyone is interested in replacing them. This guy
on eBay was very helpful in finding and supplying the correct switch. He also has several other commonly used switches available. Even the blue ones.
I am not affiliated with him in any way besides being a happy customer.
