Signal relays are commonly classified as telecommunication relays, power relays, general purpose relays and so on. Among them, the TQ4-L-12V signal relay is a kind of multi-purpose relay and is widely applicable to small current circuits. It is mainly used to control electrical signals and provides a great deal of convenience for the user.

The TQ4-L-12V signal relay is a multi-functional relay that is most suitable for switching different signals. Its maximum current rating is 2 Amps, which means that it can be used to switch small circuits and electrical signals. At the same time, it is very reliable as it has a high contact capacity, with a voltage drop across the contact of just 0.1V and a maximum switching current of 200mA.

The TQ4-L-12V signal relay features a number of different working modes and is suitable for a variety of applications. Its main working principle is to use electromagnetic signals to switch current and voltage. When the signal is applied, a magnetic field is created, which in turn activates the relay’s contact points. These contact points then close or open (depending on the type of signal) to allow current to flow or block off the path of electricity.

The TQ4-L-12V signal relay can be used in many different applications, such as lighting circuits, smoke alarm circuits, doorbells, and other small electric circuits. It is also commonly used in the telecommunications industry, where it is used to switch between landline and cellular networks. In addition, it is also used in the automotive industry to control engine fan controls, headlight controls, power steering, and more.

The TQ4-L-12V signal relay is considered one of the most reliable signal relays in the market. It is widely used in various industries and applications due to its reliability and cost efficiency. It is also highly resistant to shock and vibration, making it ideal for tough operating environments.

Overall, the TQ4-L-12V signal relay is a very useful relay for various applications. It is compact in size, reliable, and highly affordable. It is most suitable for small current circuits and small electronic signal operations.
