Ultra thin micro chip switch. 4.5x4.5x0.55. Touch mode sensing light touch switch, ultra-thin pot chip switch 4.5X4.5X0.5 light touch chip switch. Light touch switch is an electronic switch, also known as button switch, belonging to the category of electronic components. When in use, the switch function is closed and connected by applying pressure to the operating direction of the switch in order to meet the operating force conditions. When the pressure is released, the switch is immediately disconnected, and its internal structure is achieved by changing the force on the metal spring. The light touch switch is composed of insert, base, spring piece, button and cover plate. The waterproof light touch switch is added with a layer of polyimide film on the spring piece. The light touch switch with a light only serves as an indicator and is an additional function beyond the function of the switch itself. Therefore, the function of the switch itself is not affected by the presence or absence of lights. The main influencing factors on switch performance include: 1. Material of spring flakes 2. Terminal material 3. Surface treatment of spring flake terminals. In addition, the design of important dimensions of switch components also has a significant impact, including switch service life, operating feel, stability of conduction and disconnection, etc. You can choose according to your needs: 1.
