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 Description:
BS4 and BS401 series signal relays are small sizes, lightweight, high sensitivity, low power consumption of 200mW,360mW, and 450mW for options, a maximum current of 5A, coil voltage can be 5/6/9/12/24VDC, easy to choose for users, suitable for automatic remote control, communication device, RF control.

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.
