As you all have probably noticed, there are two mainstream ways that electronic devices are powered– by plugging its cord into a wall or through the use of batteries. But as our world becomes more mobile (in multiple senses of the word), it makes a lot of sense that a variety of devices are now using batteries as their source of “wireless” power. However, there are still quite a few things out there that need to be plugged into a wall. While this makes sense for large devices like a welding machine, you’ll still find most table top fans need to be plugged into the wall socket. What is preventing this change from happening?
Pushbuttons are an inherent source of problems inside of sensitive circuits. Ideally, we like to think that when a button is pressed it is either “pressed” or “not pressed” without any sort of funny business. Unfortunately, as pushbuttons are a mechanical component, a lack of funny business simply isn’t going to be the case.
