I needed same as electrical connections to it had overheated.
Just found this on eBay - Item number: 220984902798, complete with connecting wires which is good as you don't want to stress the flimsy tag connections on this little switch!
Note: I couldn't find this cut-out through CPC

Hi,Most thermal cut-outs are pretty universal,I"m assuming you mean the piece that fits over the heater tank
