Disassemble Big Hauler

[amflyer1]

I am trying to remove the boiler and cab from the chassis of a bumble bee Big Hauler. It has a red switch at the back of the cab that prohibits the cab from being removed. Does anyone know how to remove the red cap off the switch to facilitate disassembly:

Thanks,

Dear Flyer,
Simply pry it off gently using a screwdriver blade.
Have fun!

Hey Bach-man, 3 out of my 4 weren't that simple - appeared to be glued on or something. Gave up before putting enough pressure on to risk breaking switch.

What I wound up doing was taking sprue nippers and a knife to chew and cut out vertical bar separating switch and plug.
