C&K COMPONENTS Y42A01003FPLFS Momentary Action Switch

The C&K COMPONENTS Y42A01003FPLFS is a momentary action dome switch designed for a variety of applications. Its key features include short travel, providing a quick response, and good tactile feedback for user confirmation. The switch utilizes a unique dome diaphragm design, where pressure collapses the upper diaphragm to establish contact with the lower diaphragm. It is RoHS compliant, making it suitable for environmentally conscious designs. Typical applications include aircraft, instrument panels, and radio equipment, where a reliable and responsive switching solution is needed. The switch offers multiple termination options, including through-hole PCB terminations or tabs, and is available in various actuation forces to meet specific application requirements.
