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.
