When the magnet is removed, the flexible reeds spring apart and re-open the circuit. The reed switch was patented in 1941 by Walter B. Ellwood, a Bell Labs engineer. Ellwood was looking to design ...

Description: Reed Switches are used in multiple industries and applications. From implantable medical devices, to hearing aid and aerospace applications, HSI Sensing offers years of experience ...

[Lucid Science] shows us how to make some simple reed switches. Reed switches are simple components that detect a magnetic field and can close or open a circuit once detected. While not really a ...

Matrix switching systems that use reed switches for connector contacts may also use other types of magnetically actuated switches, including a bistable magnetic switch. Magnetic switches are also used ...
