help with switch wiring

[bobster]

hi guys ,
im trying to wire an on/ off  switch to an old 70's jen wah wah. the one in it before broke. it had 4 solder lugs on it.
at present i have a generic dp/dt in which works but is starting to crap out cos its not strong enough --

i have some spare heavy duty switches from jim dunlop wahs but they only have 3 solder lugs and i cant figure out how to wire them!
can anyone help?
for info , the previous switch had a jumper wire from the top two lugs [ looking down at it with pedal opened up ]
thanks !
bob
