EAO's Series 95 color-changing push-button switches come in three sizes: 15.88, 12.7, and 19.05 mm2. Three LEDs may be added on the 15.88 and 19.05 mm2 sizes and up to two on the 12.7 mm2 version. Independent LEDs offer the ability to show different stages of illumination and operating status of equipment provided by PCB circuitry. The full-face illumination provides excellent visibility, even when viewed from the side, allowing users to view the status of each function at a glance. The diffuser can be printed or engraved, or a film insert can be fitted between the diffuser and lens.
