Ultra-small tactile switches from Omron

Supplier News

Mouser Electronics, Inc., has stocked Omron’s B3U ultra-small tactile switches for high-density mounting on PCBs for mobile equipment. The B3U is one of the world’s smallest tactile switches measuring 1.2 x 3 x 2.5mm and uses only 75% of the volumetric space of similar models, giving design engineers an advantage.

Omron is a supplier of electronic components with products ranging from relays, switches and connectors to optical sensors and optical components. With a switching capacity of 1 to 50mA at 5 to 12VDC and initial contact resistance of 100m ohms max, the B3U switches feature dust-proof construction for reliable performance in harsh environments.

The B3U switches are available in top- or side-actuated configurations, with or without a locating boss, as well as a ground terminal version that provides static discharge protection.

According to Mouser, the distributor is known for its rapid introduction of new product solutions to design engineering challenges.

Omron’s B3U switches meet the challenge of handheld wireless devices requiring additional features, while maintaining their small size.

The fully RoHS compliant switches operate in a temperature range of -25°C to +70° in 60% humidity without icing or condensation. The top-actuated B3U-1000 series has a minimum life expectancy of 200,000 operations with an operating force of 153 ± 50gf. The side-actuated B3U-3000 series has a minimum life expectancy of 100,000 operations with an operating force of 162 ± 50gf.
