SUBMINIATURE BASIC SWITCHES BASIC SWITCHES SINGLE BREAK, SNAP-ACTION, COMMERCIAL & MILITARY GRADES, SUBMINIATURE, TWO WIDTHS Available in two widths, the B2 series can be specified to fit your application exactly. In addition to being available with integral actuating levers as in the B2-5 series, the B2 series is also available with the A1 series auxiliary lever actuators as shown in the B3 section. While the B2 series conforms to and is qualified to various military specifications, the same switch can be specified for commercial use at a cost savings. A choice of turret, quick connect and three lengths of printed circuit board style terminals are available for both the 0.156” and 0.200” wide models. Whether it be military or commercial applications, OTTO can provide features you select for your application. You can specify the features you require without paying for ones you don’t need. The OTTO B2 subminiature switches conform to and are qualified under MIL-PRF-8805/4, MIL-PRF-8805/106 (high temp -55°C to +205°C) and MIL-PRF-8805/109. Basic switches are designed for miniature spaces where cam or other limit actuators are used on the button. In addition, a full range of toggle, pushbutton and lever actuators are available. Features:

  • Choice of 0.156” & 0.200” wide models
  • Up to 7 amps switching
  • Sensitive movement differentials
  • Low operating forces
  • Choice of 8 terminal styles or wire leads
