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.
