Latest Patents
John J Penrose holds a patent for a magnetic switch, which is a plastic unit designed to enhance the operation of electrical devices. The magnetic switch consists of a housing that contains three essential components: a slideable magnet holder, a bracket, and a plastic leaf spring. The design incorporates keys and notches that provide distinct 'on' and 'off' positions. This innovative switch is aligned with a mercury wetted switch, allowing it to handle large current surges without sustaining damage. The mechanism operates by depressing the magnet holder against the spring bias, enabling it to slide into either the 'on' or 'off' position. Additionally, a hermetically sealed flashlight featuring this magnetic switch is also described in his patent. The flashlight includes a case that houses dry cells, and a screw-on cap with a lens that forms a hermetic seal when an O-ring is compressed. The reflector mount is aligned with the case using a notch and key system, ensuring proper alignment of the mercury wetted magnetic switch and the housing for the magnet holder.
