Reed relays are a type of electrical device that often use an electromagnet to open or close switches. LI12-1A79 is a type of reed relay that is commonly used in various applications. This article covers the appliance field and working principle of LI12-1A79.

Application Field

LI12-1A79 reed relay is widely used in consumer electronic products, electronic measurement systems, communication systems, medical systems, and other high-tech industries. It is an ideal device to control electrical signals in circuits.

For example, this reed relay variant is used as an on/off switch in remote control toys. It can also be used to control the volume of a speaker or even to control the brightness of a light. In addition, this reed relay is often used in various automatic control systems as a signal switching device.

Working Principle

LI12-1A79 reed relays operate on the same principle as standard reed switches. The LI12-1A79 relay consists of a ferromagnetic core and a single reed switch. The ferromagnetic core is suspended between a coil and a diaphragm. An electrical current is sent through the coil, which then produces a magnetic field. This field then causes the ferromagnetic core to vibrate, thus opening or closing the switch.

When the current is passed through the coil, it also creates an electromagnetic field around the reed switch and the adjacent metallic part. This field then creates a force exerting a pulling/pushing action on the switch, thereby causing it to open or close. Upon sensing the change in current, the switch will then activate and stay in its desired state (open or closed) until the current is cut off.

When the switch is closed, the contacts touch one another and an electrical connection is made. This connection then completes the circuit. In contrast, when the switch is open, no electrical connection is formed and the current is not allowed to flow through the circuit.

LI12-1A79 reed relay is designed for short-time use applications. This means that the relay must always be de-energized for a certain amount of time in order to guarantee the high performance of the device.

In short, LI12-1A79 reed relay offers a reliable and efficient way to switch electrical signals in various applications. Its efficient and simplified design, as well as the ability to operate at high frequency, makes it one of the most popular reed relays in the market today.
