Water heater micro switch operating principle

The water heater is in our kitchen space, which can occupy an important position, that water heater micro switch , do you know what it is? Today we will come to a good understanding of a water heater micro switch related introduction.

What is the micro switch of water heater

The micro switch of the water heater is a kind of fast switch which is pressure-activated, also called sensitive switch. Waterproof micro-switch of gas water heater water and gas linkage valve, including a linkage small shaft, a bracket, a micro switch body and a shift fork, the micro switch body is fixed on the bracket, the fork is disposed on the bracket through a rotation shaft, and one end of the fork is Contact with the bump on the linkage shaft, the other end of the contact with the contact of the micro switch, and the switch fork contact with the contact of the micro switch is designed into a U-shaped structure.

The micro switch is based on the pin type, which can be derived from short stroke, large stroke of the button, large stroke of the button, roller button, reed roller, lever roller, short boom type, long boom type. and many more.

Water heater micro switch working principle

The working principle is that the external mechanical force exerts force on the action reed through the transmission element (by pins, buttons, levers, rollers, etc.) and accumulates the energy to the critical point to generate an instantaneous action, so that the end of the action reed moves. Point and fixed contact quickly turn on or off. When the force on the transmission element is removed, the action reed produces a reverse action force, and when the reverse stroke of the transmission element reaches the critical point of action of the reed, the reverse action is instantaneously completed. The micro-switch has a small contact distance, a short stroke, a small power, and a rapid on-off.

The operating speed of the movable contact is independent of the operating speed of the transmission element. Micro switches are used in electronic devices and other devices for devices that require frequent switching circuits for automatic control and safety protection.

Water heater micro switch function and price

The function of the micro switch of the water heater is to control the ignition. When the water pressure reaches a certain value, the diaphragm inside the diaphragm will open the micro switch through the drive shaft. The micro switch will give a signal to the pulse igniter to start the discharge and fire, and then the solenoid valve. Received a signal, energized to open the valve to supply gas and begin to burn.

The price of water heater microswitches can be bought on the electronic market for a dollar or five cents.

Regarding the micro-switches of water heaters , I will introduce them to you here. I hope to help you, and more information on the decoration is on this site. Please stay tuned.
