515-1140-235F is a variable-length light pipe actuator designed to snap onto K5V ITT/Cannon right-angle push-button switches, providing optical transmission for illuminated switch applications. The actuator is molded from clear, transmissive 94-V0 polycarbonate material with a diffused matte finish, and features a length dimension of 0.925 inches (23.5 mm) as specified in the part number designation. The component has an outer diameter of 0.240 inches (6.1 mm) and an inner diameter of 0.157 inches (4 mm), with dimensional tolerances of ±0.01 inches for two-decimal specifications. This light pipe actuator is RoHS compliant and is commonly used in illuminated control panels, indicator systems, and user interface applications where visual feedback is required. The modular design allows for various length options in 0.5 mm increments, enabling customization for different switch and panel configurations.
