whirlpool washer dryer awg320wh, half load sw

I am repairing awg320wh integrated washer dryer, I have identified the fault (half load switch contacts burnt) I identified the parts req using whirlpool parts cd “sios” which lists as the part, kit containing four push button switches and mounting bracket. part No 481927638216. on attempting to fit the kit, I noticed that the half load switch on the machine was different to any of the switches in the kit. ie, it is a six term, two pole change over switch, the switches in the kit comprise of two single pole, three term switches, and two, single pole two term switches !
I have contacted whirlpool about this, and they cant come up with any help, they say I have the correct part, and although there are twelve variations on this model, there is only one awg320wh. I have also tried to find the part using Servis model numbers, but there are many different versions of the machine in this variation of its existence.
I have spent what seems like hours trawling through lists of push button switches of all makes, to try and find a similar switch, with no luck.
help….. has any one come across this problem
