B3AL Long-Stroke Tactile Switch

Omron's B3AL series long stroke tactile switches (SMT) are designed using the latest flexible rubber technology ensuring a long life (one million operations) with full travel and reliable feedback to the operator. The switch cap is preinstalled eliminating the need to purchase caps separately or to snap them onto the switch after soldering. The switches are offered in four standard colors and are available in pick-and-place friendly T&R packaging.
