In electrical engineering, an electromagnetic
switch. A small current passing through a
coil of wire wound around an iron core
attracts an armature whose movement closes a
pair of sprung contacts to complete a
secondary circuit, which may carry a large
current or activate other devices. The
solid-state equivalent is a thyristor
switching device.
