That's not the way it works. The wiring outside the relay is such that 
when you energize the relay it will provide currency to hold itself. 
When you step on the accelerator pedal the cut out switch will break 
this currency so that the relay cuts off. In fact, it's nothing special, 
you can use any relay you have on the shelf, it doesn't matter.

Best regards, Per in Sweden
