SWITCH SUPPORT: Brass, matte-tin plated. CONTCTS & TERMINLS: B contact material: Copper alloy, with gold plate over nickel plate. See page -13 for additional contact materials. TERMINL SEL: Epoxy. NOTE: ny models supplied with Q, B, P, S, R or G contact material are RoHS compliant. NOTE: Specifications and materials listed above are for switches with standard options. For information on specific and custom switches, consult Customer Service Center. CUTION: 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--Switch To order, simply select desired option from each category and place in the appropriate box. vailable options are shown and described on pages -10 thru -14. For additional options not shown in catalog, consult Customer Service Center. ll models are process sealed to withstand machine soldering temperatures and pressure wash cleaning methods.
