B5 series basic switches are subminiature in size and feature up
to 10 amps switching capability of 100,000 cycles. Mechanical
life is 1 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.
