In this article, the functions and working principles of micro switches for water heaters will be introduced. I don't know if you have noticed that there is a handle inside the middle and bottom of the water heater by opening the outer shell of the water heater and then turning on the water switch. Then there is a microswitch next to it.
The function and basic working principle of the micro control switch of the water heater!
In this article, the functions and working principles of micro switches for water heaters will be introduced. I don't know if you have noticed that there is a handle inside the middle and bottom of the water heater by opening the outer shell of the water heater and then turning on the water switch. Then there is a microswitch next to it.
1、 The function of the water heater microswitch:
1. A microswitch can be opened by applying water pressure and pushing the microswitch when opening the water heater. Control the operation of the water heater control panel: high-pressure ignition, solenoid valve open. (With water pressure circuit automatically opens, without water pressure circuit automatically closes)
2. If the microswitch is short circuited, the water heater will become uncontrollable and your water heater will continue to operate (high-pressure continuous combustion, solenoid valve remains open)
3. To control the water heater, it is necessary to use a microswitch. Short circuits cannot be used. This way, the solenoid valve remains open when the water heater is not in use, and natural gas will leak out, which is very dangerous.
2、 The working principle of the micro switch of the water heater:
The micro control switch is a component triggered by an internal metal contact spring. After pressing the button once, the silver dot in the microswitch and the front section of the metal contact spring, along with the lower contact foot, triggers the student once to conduct the circuit and send it to the controller. An electrical signal, then reset.
Energy conservation and emission reduction are the development direction advocated, and low energy products will be the future development direction. The design of solar water heaters and air energy water heaters as low energy consumption products has a good economic momentum for development. However, due to some limitations of the product itself, there are certain limitations in meeting consumer needs, so comprehensive energy utilization has become another direction for the development of water heaters. Solar water heaters and air energy water heaters can be used as products for Chinese new energy enterprises and are showing strong economic momentum for development. Due to their unique performance, these two categories have rapidly expanded the market and generated strong reactions among consumers.
The function and working principle of the micro switch of the water heater were shared above. The micro switches used in water heaters are commonly referred to as waterproof micro switches. It is a contact structure and quick action mechanism with a small contact interval, which performs switch actions with a specified stroke and force. Waterproof switch with drive lever. Dingyue Electronic Enterprise provides the company's original Omron OMRON waterproof micro control switches, such as the Omron micro state switch D2VW-5 series, and the Omron mouse waterproof micro switch D2FC-F-7N series.
Microswitches have the characteristics of small contact distance, short action travel, and rapid passage. Generally speaking, switches can be opened and closed without using significant force. But many people like to press hard when using it, as if the switch is not working properly. In fact, this behavior is wrong, let alone whether the pressure is related to the on-off of the microswitch. In terms of force alone, excessive pressure will definitely affect the service life of the switch. Over time, it will also cause deformation of the switch action spring, which will affect the overall performance of the switch and even cause malfunctions.
