Reed switches are interesting devices with a ton of domestic and industrial applications. We call them switches, but they’re also sensors.

The reed relay consists of a switch with magnetic contacts that move under the influence of an external magnetic or the induced field from its solenoid.

Electronic, Arduino enthusiasts and makers looking for a project to keep them busy this weekend, may be interested in a cool custom switch created by Dave Darko. That requires users to ...

Standex Electronics has created a series of mini magnetic field sensing reed switches, optimised to control up to 10W, 200V or 500mA. Called MK33, they are bare glass surface-mount reed switches with ...
