B2
Available in two widths, the B2 series can be specified to fit
your application exactly.
In addition to being available with integral actuating levers as
in the B2-5 series, the B2 series is also available with the A1
series auxiliary lever actuators as shown in the B3 section.
While the B2 series conforms to and is qualified to various
military specifications, the same switch can be specified
for commercial use at a cost savings.
A choice of turret, quick connect and three lengths of printed
circuit board style terminals are available for both the 0.156”
and 0.200” wide models.
Whether it be military or commercial applications, OTTO can
provide features you select for your application. You can specify
the features you require without paying for ones you don’t need.
The OTTO B2 sub-subminiature switches conform to and are
qualified under MIL-PRF-8805/4, MIL-PRF-8805/106 (high
temp -55°C to +205°C) and MIL-PRF-8805/109. Basic switches
are designed for miniature spaces where cam or other limit
actuators are used on the button. In addition, a full range of
toggle, pushbutton and lever actuators are available.
