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
Round Metal Dome : it’s normally used in the electronic devices with small volume due to less space demand , also has good advantage in the feature of feels ,force and longer lifetime . Oblong Metal Dome : is almost used for any products which round metal dome used , which shape is cutting off 2sides from round snap dome , when design area is too small to place round shape , it can use oblong snap dome insteaded . 4-Legged Metal Dome : when designer reserve sufficient space & request bigger stroke travel , C-series metal dome will be prior to select to use , it’s often used in the handheld device,medical device and large banking equipment . 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 . Metal dome Customized : Normally , Metal dome(snap dome) can be divided into round, 4legged, triangle, Oblong and other special-shaped . Accept to custom METAL DOME as per different requirement such as its special required Size , Specification . if any further demand you need for , please feel free to contact with us , Guanghongda Technology .
