The magnetic interlocking switch safeguarding system consists of three components: a multiple-reed switch sensor, a coded magnet, and a controller (safety) module to meet high levels of safety circuit integrity
Magnetic interlocks use a reed switch, which is electrical switch that is operated by the introduction of a magnetic field. For example, when a magnetic field is introduced, the reed switch’s normally-open
contact will close and the normally-closed
contact will open.
