The application of micro switch on mouse
the micro switch in the mouse is a component that is triggered by a metal reed inside. after the button on the mouse is pressed once, the silver point in the front section of the metal reed in the micro switch is triggered once with the contact foot below, causing the circuit to be turned on. sends an electrical signal to the computer, and then resets it. there are many kinds of mouse micro switches, and there are hundreds of internal structures. the mouse microswitch is generally based on the unassisted pressing accessory as the basic type, and a small stroke type and a large stroke type are derived.
under all the buttons on the mouse, there must be a micro switch or a tact switch, so in fact, the micro switch is the button of the mouse. the function of the button on the mouse shell is only to facilitate the user to press the micro switch. not only for the mouse, but also for various other toys. design features of mouse micro switch
the biggest technical feature of micro switch manufacturers in switch design is to prevent loss and prolong its service life. fretting loss is divided into two types: wear and fatigue. fretting wear means contact surface wear or material loss; fretting fatigue refers to the generation of fatigue cracks in metals and other materials or the reduction of fatigue life.
increasing the strength of the contact element surface is the main way to slow down the loss. it increases surface residual compressive stress through various surface treatments, such as physical (laser, ion implantation, etc. to change the surface microstructure hardening technology), chemical (surface hardening technology such as carburizing, nitriding, etc.), mechanical (shot peening, rolling, etc.) ) process to obtain special composition, structure and properties on the surface of the material to improve its wear resistance and fatigue resistance. in addition, there are also ways to strengthen the electrical capabilities of the fatigue-prone metal reeds and contacts, such as switching to silver, alloys and other metal materials.
changes in structural design can also have the effect of slowing down the loss. for example, changing the internal structure, clamping method, contact size, etc. of the component, and also changing the pressure distribution and contact mode at the contact surface, can improve the performance of anti-fretting damage to different degrees. another effective measure to slow down the fretting loss is to reduce the friction coefficient (ie friction), which can be achieved by increasing the lubricating medium.
