The company’s dome arrays in a reel format packaging were specifically designed for those looking to automate the placement process of custom Peel-N-Place (PNP) dome arrays. Metal domes are low-profile momentary switch contacts that provide quality tactile feel in pushbutton applications. With PNP arrays, multiple domes can be precisely placed in a fraction of the time it would take to place individual switches. PNP arrays from the company consist of a polyester carrier lined with a pressure-sensitive adhesive that enables metal domes to be placed directly onto printed circuit boards, flex circuits, and other surfaces. The use of PNP arrays is said to eliminate the need for soldering or individual pick and place. Metal domes from the company have a discernable “snap” feel that assures the end user that contact has been made. A variety of styles are available, including four-legged, triangle, round and custom designs. Standard sizes range from 4 mm to 20 mm, with a wide range of actuation forces. The domes are made of stainless steel with optional nickel, silver or gold plating, and typically have a life of more than 5 million cycles. Metal domes are used in many different applications, including medical instrumentation, pushbutton control panels, personal digital assistants, audio and video equipment, keypads and anywhere a low-profile momentary switch is required.
