packaging, see page F-31 for drawings and reel information.

Materials

CASE & BUSHING: Glass filled nylon 6/6, flame retardant, heat

stabilized (UL 94V-0) or 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 F-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.

NOTE: Specifications and materials listed above are for switches with standard options.
