B5 series basic switches are subminiature in size and feature up
to 10 amps switching capability of 100,000 cycles. Mechanical
life is one million cycles.
The molded housing is rugged and structurally stable. The
terminals are sealed against solder flux entering the switch and
are bright acid tin plated for excellent solderability.
A variety of actuators for pushbutton, toggle and lever actuation
are available in standard and custom configurations.
