In modern electronic automation control systems, temperature control switches play an indispensable role. It ensures that the equipment operates within the ideal temperature range by monitoring and controlling the ambient temperature, thus improving the safety, stability and efficiency of the equipment. In order to better understand the function of the temperature control switch and its application in the circuit system, this article will discuss the wiring of the temperature control switch and its working principle.

Basic Concepts of Temperature Switches

Before we delve into the wiring diagram of the temperature control switch and its working principle, we first need to have a basic understanding of the temperature control switch. Temperature control switch, as the name suggests, is based on the temperature change for switching control of electronic components. It is mainly by the bimetal for temperature sensing, according to different temperature control requirements, temperature control switch can be set at a specific temperature point trigger, open or close the operation, in order to control the circuit on and off, and then control the operation of electrical equipment.

Application areas of temperature control switches

Temperature control switches are widely used in many fields, including but not limited to:

Household appliances: such as electric water heaters, electric ovens, air conditioners, etc., through the temperature control switch to control the start and stop of the equipment, in order to achieve the purpose of energy saving and to protect the use of safety.

Industrial manufacturing: In industrial production, many production processes need to be carried out under specific temperature conditions, temperature control switches play a key role here. Medical equipment: Certain medical equipment, such as thermostats, incubators, etc., where precise temperature control is critical to experimental results.

Working principle of temperature control switches

The working principle of temperature control switches is relatively simple. When the ambient temperature reaches or exceeds the threshold value set by the controller, in order to open or close the circuit and control the operation of electrical equipment.

For example, in an electric water heater application scenario, when the water temperature is lower than the set value, the temperature control switch is connected to the heating circuit, and the water begins to heat; when the water temperature reaches or exceeds the set value, the temperature control switch cuts off the heating circuit, and the water stops heating. In this process, the temperature control switch plays the role of preventing overheating and saving energy.

Wiring of temperature control switch

Temperature control switch as an actuator, direct control circuit on and off, can be directly connected in series to the main circuit. When doing the switch signal, take the temperature signal in the equipment and pass it to the main control circuit for temperature control.

When wiring, you need to ensure that the contact is good, fixed and reliable, to avoid short circuits, broken circuits and other safety hazards. In addition, in the connection process, you need to pay attention to the voltage level and load current match, so as not to damage the equipment. Finally, after the completion of the wiring need to carry out safety tests to ensure that the temperature control switch can work properly. In general, the correct wiring is to ensure the normal operation of the temperature control switch is the key, only to do safe and reliable to play its role.

With the continuous progress of science and technology, the types and applications of temperature control switches are also constantly developing and expanding, from simple temperature control to complex environmental monitoring systems, the role of temperature control switches is increasingly significant. Understanding the wiring and working principle of temperature control switches is undoubtedly a key step in mastering this important technology.
