Specifications  
Materials  
CONTACT RATING: B contact material: 0.4 VA max. @  
20 V AC or DC max. See page F-35 for additional ratings.  
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.  
ELECTRICAL LIFE: ETX1 models: 60,000 make-and-break cycles at  
full load. All other models: 30,000 cycles.  
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.  
CONTACT RESISTANCE: Below 20 m typ. initial @ 2-4  
V DC, 100 mA, for both silver and gold plated contacts.  
9
INSULATION RESISTANCE: 10 min.  
SWITCH SUPPORT: Brass, tin plated.  
ELECTROSTATIC DISCHARGE (ESD) RESISTANT OPTION:  
M3 & S3 insulating actuator only: 9,000 V DC min. @ sea level,  
actuator to terminals. F1 conductive bushing only: Dissipates  
up to 20,000 V DC from actuator to ground. M3 & S3 actuator  
and F1 bushing options are not recommended for use together.  
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.  
DIELECTRIC STRENGTH: 1000 Vrms min. @ sea level.  
OPERATING TEMPERATURE: –30ºC to 85ºC.  
NOTE: Any models supplied with Q, B, G, P or R contact material are RoHS compliant  
and compatible.  
SOLDERABILITY: Per MIL-STD-202F method 208D, or  
EIA RS-186E method 9 (1 hour steam aging).  
NOTE: Specifications and materials listed above are for switches with standard options.  
For information on specific and custom switches, consult Customer Service Center.  
DEGREE OF PROTECTION: IP57; Protection against harmful dust  
deposit, full-scale voltage protection, temporary immersion.  
PACKAGING: Surface mount switches are shipped in tape and reel  
packaging, see page F-31 for drawings and reel information.  
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 F–26 thru F–31. 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.
