A tactile switch suitable for demanding OEM applications such as automotive instrumentation, medical equipment and process control applications has been unveiled by Omron Electronic Components. The long stroke B3AL switch is a two terminal device featuring a high operating force and long life durability. The vertically operated switch is notable for its enhanced resistance to dust penetration and a long operating life of up to 1million operation cycles which ensures long and reliable operation under extreme operating conditions.

Available in four versions, with operating forces of 1.96N, 2.45N, 3.00N and 3.50N, the long stroke switch has a pretravel of 1.3mm which is achieved by using a rubber plunger. Featuring a design with dimensions of 6.9mm x 6.0mm x 5.0mm (l x w x h) the B3AL is rated for switching currents of 1mA at 5VDC to a maximum of 50mA at 16VDC with a resistive load and features an insulation resistance of 100MΩ at 100VDC and a contact resistance of 100mΩ.

The B3AL switch supports an ambient operating temperature range of-40° to +90°C and weighs approximately 0.18g. Supplied on 12mm tape and reel, the tactile switch is designed to prevent flux penetration.
