Hmm, possibly. See part number 3931225.

The datasheet is not on farnell's site, but the manufacturer has it here: http://www.ck-components.com/14389/pcm_24mar.pdf

Worth checking the measurements and seeing if it'll fit. The two mounting lugs, side solder mount points and uneven 3 terminal spacing on the back look familiar - it's not the one that was actually used, but there are a lot of equivalents in the switch world....

edit: on the other hand, farnell appear to want to charge you 16 quid to send it...
