Internal structure of metal button switch

Metal button switches are an important component of electrical control systems, widely used in automation equipment, home appliances, lighting systems, and other fields. It usually consists of multiple parts such as buttons, housing, static and dynamic contacts, LED beads, springs, nuts, PC transparent cover, PA66 base, etc. This structural design not only ensures efficient button operation, but also provides reliable electrical connections, suitable for various industrial and commercial applications.

The materials of metal switch buttons include stainless steel, nickel plated brass, and aluminum oxide. The buttons can be equipped with LED lights or not. The types of lights include face wide range, illuminated, circular lights, power identification lights, and power identification lights combined with circular lights.

The materials of the shell include stainless steel, nickel plated brass, and aluminum oxide. If you want to make the shell colored, aluminum oxide and stainless steel vacuum plated materials will be your first choice.

LED light beads are built-in in the button or can be used as external light beads. LED lights come in single color, dual color, and mixed color options for you to choose from.

In the static state of a button switch, its contact opening and closing states can be divided into a start button (i.e. normally open button), a stop button (i.e. normally closed button), and a composite button (i.e. a button that combines normally open and normally closed contacts). When the button cap is pressed, the contact of the start button closes, and when released, it automatically disconnects and resets; On the other hand, the stop button is the opposite. When the button cap is pressed, the contacts separate and automatically close and reset after release. The design of composite buttons is more complex. When the button cap is pressed, the bridge type moving contact moves downward, first disconnecting the normally closed contact and then closing the normally open contact; When releasing the button cap, the normally open contact first opens and resets, followed by the normally closed contact closing and resetting.

The flexibility of this button switch structure enables it to meet different control requirements, whether it is a start button that requires instantaneous control or a stop button that requires maintaining a state, the button switch structure can provide a precise operating experience.

In addition, the design of metal push button switches also takes into account user convenience and safety. Through reasonable structural layout and material selection, the durability and stability of the button under frequent operation are ensured. This not only meets the functional requirements of button switches, but also enhances user satisfaction in terms of user experience.
