Smd Metal Doom Switch head 10mm 4-leg

Description

Working Principle : The snap dome is located at the conductive part on the PCB (most of which is above the gold finger on the PCB). 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 feel The Cross Metal dome , also called 4 LEG snap dome Product Model Specifications Surface Treatment Parameter Force(gf) Diameter Trip Height Service Life Round 0/1/4/5 Dimple Gold,silver nickel plating 3-10mm 0.14-0.19 ±0.05 0.21-0.25 ±0.03mm >100k times 100gf-500gf 4-Legged 0/1/4/5 Dimple Gold,silver nickel plating 4-20mm 0.23-0.28 ±0.05 1.40-1.70 ±0.03mm >100k times 100gf-600gf Oblong 0/1/4/5 Dimple Gold,silver nickel plating 4×2.88mm ~5x4mm 0.15-0.23 ±0.05 0.21-0.29 ±0.03mm >100k times 100gf-250gf Triangular Long foot /short foot /no foot Gold,silver nickel plating 3.15-12mm 0.15-0.19 ±0.05 0.21-0.25 ±0.03mm >100k times 200gf-600gf Irregular Special shape Gold,silver nickel plating
