BASIC
SWITCHES
Available in two widths, the B2 series can be specified to fit your
application exactly.
The B2 series is also available with integral lever actuators as
the B2-5 series. These are in addition to the A2 series auxiliary
lever actuators 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 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 spending 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.
