NOTE FOR DRAWINGS

Technical Terms

1. Because of restricted space we can only show a small percentage of our switch packages and dimensional drawings. Please contact the factory if

you do not see the solution you need, or if you require more detailed envelope drawings.

2. Unless otherwise noted, standard leads are AWG #20 per MIL-W-22759/9.

3. All exposed materials on packaged designs are corrosion resistant steel with the exception of the side plates on Style 7 switches which are

anodized aluminum alloy.

4. All hardware provided is corrosion resistant steel.

Electrical Life

The minimum number of cycles allowable for a switch under a specified combination of electrical load, actuation and environmental criteria. Usually

specified for the maximum current and temperature rating of the switch.

Mechanical Life

The minimum number of cycles allowable for a switch with no electrical load, and a specified combination of actuation and environmental criteria.

Contact Erosion

A general loss of material from one or both surfaces of a pair of mating contacts. This is as a result of switching electrical loads.
