Membrane switch overall performance

1. Durability: The life of the membrane switch can generally reach more than one million times. The reason for such a long life is that the action of the switch is only achieved by the vertical movement of the elastic film; although the elastic film has passed one million times Creep, but the amplitude of creep is very small, only 0.1~0.3mm (both switching stroke), plus the rationality of material selection, far from reaching the film's yield limit, so the film material can withstand more than one million times Longevity without deformation.

2. Good sealing performance: Since the membrane switch is an integrally sealed structure, the contacts of the switch are not eroded by harmful gases and are not easily oxidized; it has the characteristics of waterproof and dustproof, so it is more suitable for various harsh environments.

3. Rich colors and beautiful appearance: Membrane switches can be personalized in the design of color patterns according to the user's design concept, and reflect the comprehensive characteristics of beautiful materials, decorative beauty and beautiful craftsmanship in the decorative effect.

4. Reduce the assembly cost of electromechanical products Cost: Traditional mechanical switches need to be welded during installation, and even need to be fitted with a fixed bracket; while the installation of membrane switches is an adhesive type, as long as the adhesive tape is removed, it can be firmly adhered to the surface of the whole machine, and the lead wire outlet is inserted The socket of the rear circuit of the whole machine can be connected to the circuit in an instant.

5. Small size, light weight and reliable structure: Membrane switches can be arranged and combined into a membrane keyboard in design, which has a large setting density, and it is a sealed sheet structure composed of multiple layers of membranes, connecting all switches The wire and the lead wire are completed by screen printing at a time, and the total thickness is 1~3mm, so the volume is reduced, the quality is reduced, and the reliability is improved.
