Lighting switch

Anybody know if there's anywhere in or near Chelmsford I can buy a new lighting switch today?

 

There's Karmann Konnections in Southend, they should have one.

 

Beware though that place takes a day to walk around. What with the museum downstairs.... O0

 

Cheers guys, I went to BUGMAD today in Harlow. He told me about a guy around the corner from him that had loadsa bits so I got one from there.
