Signal relays are electromechanical switches that are designed to turn on and off in response to a signal, such as a digital or analog input. They are commonly used in applications where a low- power electronic switch needs to control a high-power electrical circuit. This makes them an ideal choice for a variety of industrial, consumer, and automotive applications. The TQ4-5V-3 is a signal relay designed to handle up to 2 amps.

The TQ4-5V-3 signal relay consists of a contactor, two form-C (SPST- NO/NC) contact blocks, and a lever actuator. The contact blocks are made from high-temperature resistant plastic and feature two pairs of individual contacts and a common or a commoner. The contactor is a single-pole, changeover relay with a load power rating of up to 2 amps. The switch is activated by an operating lever which moves the contact blocks into an open or closed position.

The TQ4-5V-3 signal relay can be used in a variety of applications. These include controlling HVAC systems, automotive ignition systems, light dimmers, motor controls, and industrial/commercial control systems. It is also suitable for low-voltage and low-current applications, such as controlling the movement of low-power DC motors or controlling the power output of solar panels.

The working principle of the TQ4-5V-3 signal relay is relatively simple. When an electronic input signal is applied (for example, from a microcontroller, logic circuit, or other device), the contact blocks are moved from the NO (normally open) position to the Closed (NO/NC) position. This closes the circuit and allows the load (motor, lights, etc.) to be energized. When the input signal is removed, the contact blocks move back to the NO position, which breaks the circuit and de-energizes the load.

The TQ4-5V-3 signal relay is designed to operate reliably and securely, even in tough environments. It has a voltage rating of 5VDC, is rated to operate up to 85°C, and can handle up to 2 amps of load current. It also has an LED indicator that shows when the relay is energized and can be easily wired using screw terminals.

The TQ4-5V-3 signal relay is a reliable and simple solution for controlling industrial, consumer, and automotive applications. It is designed to easily control low-power electronic circuits, providing the necessary flexibility and reliability for a wide range of applications. With its high-temperature resistant plastic contact blocks, up to 2 amp current handling, LED indicator, and screw terminals for easy wiring, the TQ4-5V-3 is a great choice for any application that requires the control of low-power electronic circuits.
