When pressed, the central dimple of the dome is concave and contacts the circuit on the PCB , Thus, the circuit is formed, and the current passes through, and the whole product can work successfully . With the help of the conductivity of the metal metal, it plays a role of high-quality switch between the operator and the product. The stable click ratio & longer life-time are used to provide the operator with high-quality tactile feelMajor ParameterProduct ModelSpecificationsSurface TreatmentParameterForce(gf)DiameterTripHeightService LifeRound0/1/4/5 DimpleGold,silver nickel plating3-10mm0.14-0.19 ±0.050.21-0.25 ±0.03mm>300k hit100gf-500gf4-Legged0/1/4/5 DimpleGold,silver nickel plating4-20mm0.23-0.28 ±0.051.40-1.70 ±0.03mm>300k hit100gf-600gfOblong0/1/4/5 DimpleGold,silver nickel plating4x2.88mm ~5x4mm0.15-0.23 ±0.050.21-0.29 ±0.03mm>300k hit100gf-250gfTriangularLong foot /short foot /no footGold,silver nickel plating3.15-12mm0.15-0.19 ±0.050.21-0.25 ±0.03mm>100k hit200gf-600gfIrregularSpecial shapeGold,silver nickel platingAccording to the customer's needs, it can be customizedNote: all kinds of metal shrapnel can be customized according to the design specificationsF A QQ1: Are you Trading company or manufacturer ?A:We are a Professional Trading & Manufacturer Integrated .Q2 :Can you offer OEM Service ?A:Surely Okay , we have Seasoned OEM service experience .Q3:what is the Lead time of sample ?A :It takes 2-7working days depends .Q4:How fast can i get the Quotation ?A:30mins ~ 24Hours depends .Please do not hesitate to contact with us , if you have any inquires .
