Tactile switch for tough applications


Omron has unveiled a new tactile switch suitable for demanding OEM applications such as automotive instrumentation, medical equipment and process control applications. The long stroke B3AL switch is a two terminal device


featuring a high operating force and long life durability. The vertically operated switch is noted for its resistance to dust


penetration and an operating life up to one million cycles. Available in four versions, with operating forces of 1.96, 2.45, 3.00 and 3.50N, the switch offers a 1.3mm pre-travel using a rubber plunger.


Measuring 6.9 by 6.0 by 5.0mmthe B3AL is rated for 1mA at 5VDC to a


maximumof 50mA at 16VDC with a resistive load. It features an insulation resistance of 100Mohmat 100VDC and a contact resistance of 100mohm. Operating temperature range is -40 to 90°C.Weight is 0.18g.


Supplied on 12mmtape and reel, the switch is designed to prevent flux


penetration.Minimumorder quantity is 1,400 pieces. www.components.omron.eu


Tiny switch is well protected


Claimed to be the only IP68-rated ultra-miniature tactile switch, C&K’s upgraded KMT0 Series stays functional under water for a minimumof five hours at 2m depth. The switch also resists


conformal polymer coatings and offers a lifespan exceeding 300,000 electrical andmechanical cycles.


Measuring 3.0 by 2.6 by 0.63mm(or 0.65mm) and


featuring both IP sealing and an extended life cycle, these RoHS-compliant, halogen-free switches suit handheld and portable electronic devices such as hearing aids,mobile phones,MP3 accessories and Bluetooth headsets.


Specifications include: 0.5VAmaximumpower rating;


20mV to 32Vdcminimum/maximumvoltage; and 1mA to 50mAminimum/maximumcurrent. Operating temperature range is -40 to 85°C.
