ULTRA SMALL SUBMINIATURE BASICS
SINGLE BREAK, SNAP-ACTION, COMMERCIAL & MILITARY GRADES, ULTRA SMALL SUBMINIATURE
BASIC
SWITCHES
B1
The B1 series basic switches are ultra-subminiature in
size, designed to reliably switch low level signals as
well as up to 2 amps switching capacity for a minimum of
25,000 cycles. Mechanical life expectancy is in excess of
one million cycles.
The molded housing is rugged and structurally stable.
The terminals are molded-in and sealed against solder flux
entering the switch. The terminals are available in a choice
of double turret solder style and 0.020” x 0.025” PC pins.
The B1 series is also available with integral lever actuators
as B1-5 series.

B1-5 Integral Lever Basic Switches
B1-5 series basic switches feature integral actuating
levers. The lever is built-in so that the switch and actuator
are one assembly.
Making the lever actuator an integral part of the basic
switch case makes sense and saves money, too. Better
precision, no parts to assemble and more variety add up
to a cost saving proposition.
