Ultra-small Tactile Switch
B3U
Ultra-small-sized Tactile Switch with High
Contact Reliability: 1.2 x 3 x 2.5 mm (H x W x D)
? Industry’s smallest switch* allows high-density mounting on
PCBs for mobile equipment.
*As of October 2006 (according to OMRON survey).
? Dust-proof construction provides high reliability in dusty
environments.
? Surface mounted: Ideal for high-density mounting.
? Models with ground terminals are available for protection
against static electricity.
? RoHS Compliant
