All of you guys with broken or yellowed rockers - you can replace just the actuator cover for less than $6.50 each, instead of a new switch for $25+. These are the Honeywell part numbers, available through Newark at (800) 367-3573, ask for Samantha at extension 85157:

12PA6 - Translucent
12PA4 - Transparent
12PA5-W - White
12PA5-Y - Yellow
12PA5-G - Green
12PA5-R - Red
12PA5-BL- Blue
12PA5-BK - Black

I'm going to order 10 in white.
