scope:

This specification covers the general requirements for molded silicone rubber boots which can be used on component parts such as toggle and pushbutton switches, circuit breakers, and rotary-actuated parts such as rotary switches, variable resistors, capacitors, inductors, and transformers. The boots protect the component parts-actuating mechanism from sand, dust, water and other contaminants, and seal the panel on which the component parts are mounted.

The boots covered by this specification shall be one of the types and styles as shown below. The applicable information shall be as shown on the individual specification sheet (see 3.1).

Type A - For panel mounted toggle switches and circuit breakers.

Style 1 - One-hole mounting, enclosed.

Style 3 - One-hole mounting, through.

Style 4 - Three-hole mounting, through.

Style 6 - One-hole mounting, miniature, enclosed.

Style 7 - One-hole mounting, subminiature, enclosed.

Style 8 - One-hole mounting, subminiature, through.

Style 9 - Five-hole mounting, through.

Style 10 - Panel bushing seal only.

Type B - For bushing mounted pushbutton switches.

Style 1 - One-hole mounting adapter type.

Style 2 - One-hole mounting drilled panel.

Style 3 - One-hole mounting through.

Style 4 - One-hole mounting miniature, drilled panel.

Style 5 - Three-hole mounting (for telephone handset switches).

Type C - For bushing mounted rotary actuated parts.

Type D - For use as seals for lever operated circuit breakers.

Style 1 - Panel mounted without mounting frame.

Style 2 - Panel mounted complete with mounting frame.
