Recessed magnetic door switches are made with the same magnetic reed switches used for surface-mount alarm contacts. Instead of a rectangular housing, recessed alarm contacts have a cylindrical case. This makes them easy to install, just by drilling a hole of the proper diameter. The magnets are also designed with the same type of cylindrical housing.

This sensor is essentially a reed switch, encased in an plastic shell. Normally the reed is 'closed'.  The other half is a magnet. When the magnet is less than 23mm away, the reed switch closes to create a circuit. They're often used to detect when a door or drawer is open, which is why they have mounting tabs. You can mount them by using screws ro hold them in place.
