PACKAGING: Surface mount switches are shipped in tape and reel packaging, see page G-35 for drawings and reel information.
Materials
CASE & BUSHING: Glass filled nylon 6/6, flame retardant, heat stabilized (UL 94V-0). SA surface mount: High temperature material, glass filled 4/6 nylon, flame retardant, heat stabilized (UL 94V-0). F1 conductive bushing option is impregnated with carbon fibers. ACTUATOR: M3 & S3 anti-static actuator: Nylon 4/6, black standard (UL 94V-0). All other actuators: Brass, chrome plated. Internal o-ring seal standard with all actuators. SWITCH SUPPORT: Brass, tin plated. CONTACTS & TERMINALS: B contact material: Copper alloy, with gold plate over nickel plate. Q contact material: Copper alloy, silver plated. See G-35 for additional contact materials. TERMINAL SEAL: Epoxy.
NOTE: Any models supplied with Q, B, G, P or R contact material are RoHS compliant and compatible. 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.
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 G-31 thru G-35. For additional options not shown in catalog, consult our Customer Service Center. All models are process sealed to withstand machine soldering temperatures and pressure wash cleaning methods.
