What is snap dome?
Home > Products > Standard Domes. Our tactile metal domes are momentary switch contacts that, when used in conjunction with a printed circuit board, flex circuit, or membrane, become normally-open tactile switches.
What are tactile dome switches?
Tactile dome switches, also known as snap domes, are normally open momentary contacts that provide a crisp tactile feel, letting the user know the button was pressed. Metal domes offer many key advantages over other switch solutions. Low profiles and high life cycle ratings make tactile metal domes a reliable choice.
What are metal domes used for?
moreEngineers often use metal domes in electronic applications. However, a lesser-known use case for metal domes is as a pressure switch. As a result, metal domes are an overlooked solution for air or water pressure switches.
What is a dome keyboard?
Dome-switch keyboards are a hybrid of flat-panel membrane and mechanical-switch keyboards. They bring two circuit board traces together under a rubber or silicone keypad using either metal “dome” switches or polyurethane formed domes.
How do dome switches work?
Rubber dome switches are very common. They use small, flexible rubber domes, each with a hard carbon center. When you press a key, a plunger on the bottom of the key pushes down against the dome, and the carbon center presses against a hard, flat surface beneath the key matrix.
What is a metal dome?
Metal domes (metal snap domes, or tactile metal domes), made of stainless steel, are momentary switch contacts that, when used in conjunction with a PCB, flex circuit, or membrane, become normally-open tactile switches.
Are rubber dome key switches good?
Glossaries. Rubber dome switches are now the most common switch technology in keyboards. Rubber dome switches use small rubber coverings that are pushed down to complete a circuit. Their largest advantage is their considerably lower cost compared to mechanical switches.
