OTTO B3S-5 Sealed Basic Switches with Levers are made with an integral actuating lever, combining the switch and actuator into one assembly. Sealed to IP68S, OTTO B3S-5 snap-action switches are tested to 1 million cycles at the logic level, offering reliable operation in demanding applications. The switches also show precision in terms of accuracy and repeatability. This subminiature switch series is designed for use in places where space is limited, including internally within toggle, pushbutton, and limit switches. B3S-5 works well in the aerospace, industrial, and material handling markets for applications such as conveyor belts, forklifts, ON/OFF switches, door latching mechanisms, fire suppression systems, and timing devices.
