The C&K COMPONENTS EDM450AUAC0LFS 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 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 space is limited and reliable switching is essential.
