MIL-PRF-8805/76 (0.200 inches wide)
OTTO’s B3-2XXXX series is a sub-subminiature switch that
meets all requirements of MIL-PRF-8805/76. Designed to
switch at least one million mechanical cycles, the B3 surpasses
the requirements of the military in these categories: contact
resistance less than 25mΩ, contact pressure, contact bounce
and overall cycle life. For MIL-PRF-8805/76 requirements,
B3-22141 has standard silver with gold contacts, SPDT double
break two circuit (Form Z), solder terminals in thermoset case
material. Gold plate contacts are available for non-military
applications. UL recognized and CSA certified models available.

MIL-PRF-8805/101 (0.156 inches wide)
For your really difficult projects, try OTTO’S B3 series. They
meet the OTTO inspired MIL-PRF-8805/101 specification. Only
0.156” thick, think of all those extra 0.044” you can use in those
tight ganged jobs. With the B3 series, you can get an extra pole
in where only four MIL-PRF-8805/76s fit, with room to spare.
Examine the characteristics. With the MIL-PRF-8805/101, the
only thing you give up is the extra space the MIL-PRF-8805/76
takes. Cycle life, very low contact resistance, higher than normal
contact pressures, minimal contact bounce...everything is exactly
as provided by the MIL-PRF-8805/76 specification.
For MIL-PRF-8805/101 requirements, B3-11141 (PC pin) and
B3-12141 (turret) have silver with gold contacts and SPDT
double break (Form Z) contact. For commercial applications,
a variety of contact forms, special forces and gold plate
contacts are available. Most versions are also UL recognized
and CSA certified.
Great circuit versatility is available with either switch style. You
have your choice of normally open (Form X) or closed (Form Y),
3 terminal (Form C) and 4 terminal (Form Z) SPDT double break.
