I had design a device that involve a mini circuit that use a reed switch. After all is said and done, I am told due to patent law I CANNOT use a magnet as a actuator. I need a THING that is reasonably cheap that can activate a reed switch. The current design call for a 0.5" diameter by 0.125" thick button magnet. Anyone who have an idea that can save me would be sincerely appreciated. I need all the help I can get.
