What is the working principle of the dial switch we often use and what should it be? Now let's introduce it to you.
Although you usually use the dial switch, but how does it work? Many friends are not clear, the next edition will give you a detailed introduction.
The working principle of the switch is introduced.
External mechanical force acts on the action reed by pulling the switch transmission elements (pins, buttons, levers, rollers, etc.). Instantaneous action occurs when the action reed moves to the critical point, so that the dynamic contact at the end of the action reed is swiftly connected or disconnected from the fixed contact point.
When the action force on the transmission element is removed, the action reed has reverse action force. When the reverse stroke of the transmission element reaches the critical point of the reed action, the reverse action is instantaneously completed. The touch distance of the switch is small, the action stroke is short, the press power is small, and the switch is switched on and off quickly. The speed of the moving contact has nothing to do with the speed of the transmission element.
