Reed switches are binary contactless sensors that nowadays have a very wide range of application. The reed technology allows a contactless switching of an electrical signal or closing an electric circuit with the help of a magnetic field.
Due to its sealed construction, it is possible to use reed switches in in all conceivable environmental conditions. Brake fluid level monitoring, monitoring of the tire pressure or safety monitoring of the doors of household appliances are only a handful of examples where reed switches can be used.
