SWITCHES

B2

SINGLE BREAK, SNAP-ACTION, COMMERCIAL & MILITARY GRADES, SUBMINIATURE, TWO WIDTHS

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.

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.
