C&K COMPONENTS Y42A01000FPLFS Momentary Action Switch

The C&K COMPONENTS Y42A01000FPLFS is a momentary action dome switch designed for applications requiring a compact and reliable switching solution. Its key features include short travel, providing a responsive feel, and good tactile feedback for user confirmation. The switch's construction utilizes a unique dome diaphragm design, where pressure collapses the upper diaphragm to establish contact with the lower diaphragm. It is RoHS compliant and suitable for use in aircraft, instrument panels, radio equipment, and other demanding environments. The switch offers multiple termination options including through-hole PCB terminations or tabs, and is available with various actuation forces to meet specific application requirements.
