NOTE:

Specifications and materials listed above are general specifications for switches

with standard options. For information on specific and custom switches, consult Customer

Service Center.

CAUTION:

PC mounting layouts and pads as shown are designed to be compatible with the

latest equipment and reflow techniques. Care should be taken in the design and location of

PC lands to suit individual needs. Orientation relative to reflow direction may significantly

impact solder joint integrity.
