![]() ![]() This entire process gets completed in a second or two and the momentum generated by the thumb is strong enough to create a 7kV voltage spark that lights the air-gas mixture near the burner. it lists many parts not included on my oven- my oven has no clock, fan or light, unless you count the rangehood fan and light. This mechanical force generated by pressing the hammer assembly causes the crystal to generate voltage which is carried by the electrodes at the ignition head to generate a spark. The ignitor/spark module is in series with a switch and all the spark gaps operate at the same time. Hence the complete assembly is back to its normal state. The moment the impact is created the inner spring pulls the metal rod back to its normal position and the outer spring in turn pulls the push button back to its normal state. At a certain point the spring force is enough to overcome the internal wall force and forces the hammer to move further in and strike the impact pad with a huge force of the inner spring. As we keep the pressing the push button and since the hammer is blocked from moving further in, the inner spring gets loaded. Used with permission.The movement of the hammer is not straight and it is held at the second radius transition point.
