Using this toggle switch is easy. First, make sure your gas stove is turned off and unplugged. Then, find the old switch and carefully remove it. Align the new switch in the same position, insert it into the 20mm mounting hole, and connect the 2 X 4.7mm spade terminals. Once connected, plug in your stove and test the oven light. As for maintenance, keep the switch clean by wiping it with a dry cloth. Avoid using abrasive cleaners as they may damage the black finish. If you notice any problems like the switch not working properly, contact us right away. Also, always double - check the model compatibility before purchasing to ensure a perfect fit.
