Push Button On Off Switch For Water Heater
The water heater Push Button on-off Switch is a quick switch actuated by pressure, also called a sensitive switch. The waterproof micro switch of the gas water heater water-gas linkage valve 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 set on the bracket through a rotating shaft. One end of the shift fork is in contact with the bump on the small linkage shaft, the other end is in contact with the contact of the microswitch, and the fork position that contacts the contact of the microswitch is designed into a U-shaped structure. Its working principle is that external mechanical force acts on the action reed through transmission elements (press pins, buttons, levers, rollers, etc.).
After accumulating the energy to a critical point, it produces instantaneous action, making the end of the action reed touch Point, and fixed contacts are quickly connected or disconnected. When the force on the transmission element is removed, the action reed produces a reverse action force. When the transmission element’s reverse stroke reaches the reed action’s critical point, the reverse action is instantaneously completed.
Micro Switch Introduce
The contact distance of the microswitch is small, the action stroke is short, the pressing force is small, and the on-off is rapid. The function of the water heater Push Button on-off Switch is to control the ignition. When the water pressure reaches a certain level, the diaphragm inside will open the microswitch through the top of the drive shaft. The micro switch will signal the pulse igniter to start discharging and ignition. Then, upon receiving the signal, the solenoid valve power on and open the valve to supply gas and start burning.
The speed of the moving contact has nothing to do with the speed of the transmission element. Microswitches in electronic equipment and other automatic control and safety protection devices require frequent circuit switching.
