gas interrupter replacement

This small but very important brass/electrical/valve needs to receive a continuous steady voltage from the thermocouple which is being heated by the gas flame. If flame goes out, or heat on thermocouple gets too low, voltage to interrupter falls and the gas flow is stopped. The interrupter contains a small electrical coil which holds the gas valve open when sufficient voltage is received from thermocouple. I tested my new thermocouple when heated and saw 30 millivolts going to interrupter and flame indicator so plenty to work with. Get the right part and good connections and you won't have your gas flame die out for some reason after initially lighting.Good genuine parts are a must for reliability and that is what I have now.
