BL-Series has back-lit switch & crisp tactile feedback ǀ Snaptron

Home > Products > Standard Domes > BL-SERIES

BL-Series domes have 4 legs and were devised for applications that require a back-lit switch with crisp tactile feedback. The hole in the center of the dome allows for the placement of an LED directly behind the dome switch rather than off to the side. The result is a more intense lighting effect.

BL-Series tactile domes can be mounted on single or double-sided printed circuit boards, flex circuits, or membranes. BL-series domes can also be packaged in cartridges. This enables quick and accurate placement using the Dart™ dome placement pen or the SureShot™ automated dome placement machine.

Contact Snaptron for pricing, to order, or to request samples of BL-Series domes.
