Typical Applications
• When backlighting and switch are
required to be a “2 in 1” component
• The dome contact secures a superior
contact reliabilityin time
• The ergonomics of K5V provides a
long travel, a sharp tactile feel and
an audible click
• Server, storage, automotive, network
infrastructure, medical
