Electromagnetic relay
Electromagnetic relays are generally composed of iron cores, coils, armatures, contact springs, and the like.
As
long as a certain voltage is applied to both ends of the coil, a
certain current flows in the coil, thereby generating an electromagnetic
effect, and the armature will absorb the pulling force of the return
spring against the iron core under the action of the electromagnetic
force attraction, thereby driving the armature. The moving contact is in contact with the stationary contact (normally open contact). When
the coil is de-energized, the electromagnetic suction force also
disappears, and the armature returns to the original position in the
reaction force of the spring, so that the movable contact and the
original static contact (normally closed contact) are released. This is sucked and released, thereby achieving the purpose of turning on and off in the circuit. For
the "normally open, normally closed" contacts of the relay, it can be
distinguished as follows: a static contact that is in an open state when
the relay coil is not energized, called a "normally open contact"; a
static contact that is in an on state It is a "normally closed contact". Relays generally have two circuits, which are low voltage control circuits and high voltage working circuits.
