MIL-PRF-8805/76 (0.200 inches wide)

OTTO’s B3-2XXXX series is a subminiature switch that is qualified

to 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

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 plated 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 are

qualified to 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-8805/76’s 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, 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.

APPLICATIONS

OT TO subminiature switches are designed to meet all

applications requiring MIL-PRF-8805/76 or MIL-PRF-8805/101

switches. Basic switches are designed for miniature spaces

where cam or other limit actuators are used. In addition, toggle,

pushbutton and lever actuators are available.
