How do I fix the toggle switch on my popcorn machine?

Hints for getting the best popped corn: Don't pop popcorn in butter as the butter will burn before it can get hot enough. Popcorn pops best in temperatures of 400-460 degrees F. If your oil starts to smoke which happens at 500 degrees F, you've got it too hot. Any oil will work. Use enough oil to cover the bottom of the pan. For your health, you should choose a light cooking oil or better yet, skip the oil all together and use an air popper. The movie houses use yellow dyed coconut oil which does a great job of popping the popcorn although there are healthier oils you can use than coconut oil. To see if you have the oil hot enough, drop a couple of kernels into the hot oil. If it's hot enough, they should pop in just a few seconds. If you don't have a popper, any thick bottomed, high walled pan will do. Popcorn can even be easily made in a Dutch oven over a camp fire. When your oil is the right temperature, pour in your popcorn, shaking the pan to cover all the seeds in oil. Do this with the lid on to prevent burns should the hot oil try to splash out of the pan. Using a lid helps the kernels to heat more evenly and keeps the popping corn from flying all over the place. (If you are using a popcorn popper, shaking it isn't necessary because of it's rounded bottom.) As it begins popping, it's important to continue to shake a flat-bottomed pan. This helps any un-popped kernels to settle to the bottom of the pan where they can pop. As soon as you hear the popcorn stop popping, pull the pan off the heat and pour the popcorn into another container. It will burn if you leave it in the hot pan.

What can you do if you've done everything right but your popcorn still doesn't pop very well? As mentioned above, popcorn must have about 13.5 to 14% moisture to pop properly. This is because as the popcorn kernel is heated, the moisture inside the seed is turned to steam creating a huge inner pressure. As this pressure continues past the shell's strength to keep it in, the skin ruptures and the inner starchy layer of the kernel greatly expands and turns itself inside out. If the moisture isn't there, this pressure build-up can't happen. If you find your popcorn has excessive old maids (un-popped kernels) in it, the problem might be that it lacks moisture. Place 3 cups of un-popped popcorn into a quart bottle. Add a tablespoon of water, put the lid on and shake it to get water on all the kernels. If the water puddles in the bottom of the bottle, shake it again every 10 minutes until enough of the water has been absorbed to prevent puddling. Now let it sit for two or three days while the moisture is evenly distributed into the kernels. If it still doesn't pop correctly, repeat this process but add no more than 2 teaspoons of water the second time. Yes, it's also possible to get it so moist it won't pop, so definitely, don't add water a third time. Lastly, you can even take your old maids that didn't pop, rejuvenate them with water using the above process and re-pop them. (With a measurement of three cups un-popped popcorn, 1 tablespoon of water will increase the moisture content 2.5%. A teaspoon of water will increase the moisture level almost 1%. Air dried popcorn will probably never get below a 10% moisture content on it's own, so adding even two tablespoons of water would be pushing it, raising the moisture content to 15% - that is if it started out at a moisture level of 10%.)
