    The micro switch is a fast switch that is pressed and actuated, also called a sensitive switch. A small-stroke, instantaneous action main electric appliance. The micro-switch is a small contact switch that is turned on when the hand is touched. The factory is often used as a short-circuit and over-current protection inside the large switch. When the external mechanical force acts When the button is operated, the operation button moves downward and the spring is stretched by the hook. When the spring is pulled to a certain length, the moving reed moves rapidly downward, and the contact at the right end of the moving reed turns into contact with the normally open contact below, thereby realizing the circuit conversion. If the external force is removed, the contact is instantaneously converted by the spring restoring force. With the addition of some rollers or clamps, other types of micro-switches can be derived to suit different applications. Widely used in mouse, household appliances, industrial machinery, motorcycles, etc., the switch is small, but plays an irreplaceable role.

    The working principle of the micro switch is: the external mechanical force acts on the action reed through the transmission element (by pin, button, lever, roller, etc.), and the energy is accumulated to the critical point, and the instantaneous action is generated to make the action reed The moving contact at the end is quickly turned on or off with the fixed contact. When the force on the transmission component is removed, the action reed generates a reverse action force, and when the reverse stroke of the transmission element reaches the critical point of the action of the reed, the reverse action is instantaneously completed. The micro switch has a small contact pitch, a short stroke, a small power, and a fast switching. The speed of the moving contact is independent of the speed of the transmission element. The micro switch is based on the pin type, and can be derived from the button short stroke type, button large stroke type, button extra large stroke type, roller button type, reed roller type, lever roller type, short boom type, long boom type. and many more. The micro switch is used in electronic devices and other devices for devices such as automatic control and safety protection of frequently changing circuits. The micro switch is divided into large, medium and small. It can be waterproof (used in liquid environment) and common type according to different needs. The switch connects two lines to provide on/off control for electrical appliances and machines.

    The control of the micro switch is realized by the throttle cable cam that controls the throttle opening. The micro switch is installed at the appropriate position of the cable cam. When the throttle cable cam returns to the position, it can withstand the micro switch arm, disconnect the relay solenoid power supply, and the relay is disconnected.
