Product 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
Triangular metal domes are generally divided into four types according to their specific structures
1. Footless, NT Series
2. Short LEG (0.8 * 0.8mm), ST series
3. Middle LEG (0.8 * 1.5mm), MT series
4. Long LEG (0.8 * 3.0 mm), LT series
Triangle Metal Dome : Under the conditions of small designed space,requested good feels & must meet bigger pressing force ,Triangle shape will be the best option , also it’s divided into w/feet or w/o feet , and it’s decide by PCB thickness & assembly method .
