Surface Mountable Illuminated Switch LS20 Series Features
SMD() LED1
superb surface-mountable illuminated switch integrated with LEDs into super-miniature package. One-color two-colors type available. color illumination combination four:red, orange, yellow green. Nonilluminated type also available upon request. With chip mounting machine, "LUMISWITCH" automatically mounted soldered reflow. mounting space greatly reduced, while allowing higher density mounting. addition, number parts time mounting onto substrate also reduced,resulting lower production costs. Super-miniature package allows highdensity mounting. product delivered either taping package, bulk package mounted substrate
