Just to make sure I understand since I've never done any significant electronics work. The relay has 5 pins. The two small wires are going to the pins that control the electromagnetic switch. The pin between those two is the common pin. Then with the two left, the one on the wide trace is the normally open pin and the one not connected to a trace is the normally closed. So then when current is applied to the small wires it closes the switch which disconnects the normally closed path and connects the normally open path.

Would it be possible to jumper the common and normally open pins with some sort of temperature fuse so if the the heat bed ended up getting too hot the fuse would blow?

I've got an Aoyue 9378 60 Watt soldering station with a 10 piece set of tips. But my usage of it so far has been splicing wires, doing EC3 and EC5 and motor/esc connections for my RC stuff. And that hasn't been a lot. So I have the right tools, just not a lot of technique with it yet :P
