water heater micro switch what role? water heater is a must for every bathroom, in our daily life plays a very important role. The water heater micro switch, do you know what it is? The following content will give you a detailed introduction to the structure of the water heater micro switch, the working principle of the water heater micro switch and other related content.

What is a water heater micro switch?

Water heater micro switch is a micro switch used in water heaters. A waterproof micro switch embedded on the water-gas linkage valve of the water heater. The water heater includes a small linkage shaft, a bracket, a micro switch body and a shift fork. The micro switch body is fixed on the bracket, and the shift fork is arranged on the bracket through a rotating shaft. One end of the shift fork is in contact with the bump on the small linkage shaft, and the other end is in contact with the contact of the micro switch. The part of the fork in contact is designed as a U-shaped structure.


What is a micro switch?

Micro switch is a fast switch actuated by pressure, also called a sensitive switch. Its working principle is: the external mechanical force acts on the action reed through the transmission element (press pin, button, lever, roller, etc.), and accumulates the energy to the critical point, resulting in instantaneous action, so that the end of the action reed The moving contact and the fixed contact are quickly connected or disconnected. When the force on the transmission element is removed, the action reed produces a reverse action force. When the reverse stroke of the transmission element reaches the critical point of the reed, the reverse action is completed instantaneously. The micro switch is based on the pin type, which can be derived from the button short stroke type, the button large stroke type, the button large stroke type, the roller button type, the reed roller type, the roller type, the short moving arm type, the long moving arm type, etc.

What is the function of the water heater micro-switch?

The function of the water heater micro-switch is to control the ignition. When the water pressure reaches a certain level, the diaphragm inside will open the micro-switch through the top of the drive shaft. The micro-switch gives the pulse igniter a signal to start discharge and ignition. After the solenoid valve receives the signal, the valve is energized to open the valve to supply gas and start burning.


How to choose the micro switch of water heater?

Because the voltage of water heater is large, the micro switch with high current characteristics should be selected. It is recommended to dongnan the micro switch KW3A series micro switch, which has the characteristics of high current and high temperature resistance. The current is (10/16/21/25A) selectable, and the temperature resistance can reach 125 degrees Celsius. In the peer of many choices, quality and price is also very cost-effective. dongnan micro switch manufacturer, with more than 20 years of research and development production experience, main: micro switch, waterproof micro switch home, automobile micro switch switch etc. Widely used in auto parts, home appliances, electronic equipment, automation equipment, communication equipment, automotive electronics, instrumentation, medical equipment, power tools and other fields, and become an important customer in these fields. All products have passed international certification such as ENEC, UL, CUL, CE, CQC, etc., and comply with RoHS,Reach and other environmental protection agreements.
