NOTE:

Any models supplied with Q, B, P, S, R or G contact material are RoHS compliant. For

the latest information regarding RoHS compliance, please go to: www.ittcannon.com/rohs.

NOTE:

Specifications and materials listed above are 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.

Build-A-Switch

To order, simply select desired option from each category and place in the appropriate box. Available options are shown

and described on pages A-8 thru A-11. For additional options not shown in catalog, consult Customer Service Center. All

models are process sealed to withstand machine soldering temperatures and pressure wash cleaning methods.
