Snap Domes

Snap domes (metal snap domes)are momentary switch contacts that, when used in conjunction with a printed circuit board, flex circuit, or membrane, become normally-open tactile switches. They function in the following way: The metal domes are placed on the printed circuit board by means of pressure-sensitive adhesive tape. In their relaxed state, the metal domes rest on the outer rim of the primary pathway. When pushed, the domes collapse and make contact with the secondary pathway, thereby closing the circuit. More...

Dome Arrays

Dome arrays (dome sheets) are the most cost effective solution for a simple switch with a superior tactile interface between your equipment and the user. A metal dome array is a kind of PET sheet that carries metal dome contacts. It is applied to PCBs to function as switches of mobile phones and electric home appliances. Compared to the membrane polyester switch which was formerly used, it gives good click-feeling. It also gives much longer lasting life span compared to poly dome sheets. It also takes place of down going productivity of tact switches with its potential productivity. More...
