1 Form C 3A 6 Pin 12V Signal Relay 0.2W PCB For Computer Motherboard
12V Relay Working Principle:
Electromagnetic relays are generally composed of an iron core,
coil, armature, contact reed, and so on. As long as a certain
voltage is applied to both ends of the coil, a certain current will
flow through the coil, thereby generating an electromagnetic
effect. The moving contact and the static contact (normally open
contact) are sucked together. When the coil is de-energized, the
electromagnetic suction will disappear, and the armature will
return to its original position under the reaction force of the
spring so that the moving contact and the original static contact
(normally closed contact) will be released. In this way, it is
attracted and released, so as to achieve the purpose of conducting
and cutting off in the circuit. For the "normally open and normally
closed" contacts of the relay, it can be distinguished in this way:
the static contact that is in the off state when the relay coil is
not energized is called "normally open contact"; the static contact
in the on the state is called "normally closed contact".

12V Signal Relay introduce:
A relay is an electrical control device, which is an electrical
appliance that makes a predetermined step change of the controlled
quantity in the electrical output circuit when the change of the
input quantity meets the specified requirements. It has an
interactive relationship between the control system and the
controlled system. Usually used in automated control circuits, it
is actually an "automatic switch" that uses a small current to
control the operation of a large current. Therefore, it plays the
role of automatic adjustment, safety protection, and conversion
circuit in the circuit.
