Other Ratings

Materials & Finishes

Environmental Data

• Operating Temp Range: JS02 Extended Actuator: -20°C through +70°C (−4°F through +158°F); JS04 Flush Actuator: -30°C through +85°C (−22°F through +185°F)
• Humidity: 90 ~ 95% humidity for 96 hours @ 40°C (104°F)
• Vibration: 10 ~ 55Hz with peak-to-peak amplitude of 1.5mm traversing the frequency range & returning in 1 minute; 3 right angled directions for 2 hours
• Shock: 50G (490m/s²) acceleration (tested in 6 right angled directions, with 5 shocks in each direction)

PCB Processing

• Soldering: Reflow Soldering Recommended. See Profile A in Supplement section. Manual Soldering: See Profile A in Supplement section. Note: Switches are packaged in OFF position and should be soldered in OFF position.
• Cleaning: These devices are not process sealed. Hand clean locally using alcohol based solution.

Standards & Certifications

• Flammability Standards: UL 94V-0 rated cover & base

The JS Series slides have not been tested for UL recognition or CSA certification. These switches are designed for use in a low-voltage, low-current circuit. When used as intended in a low-voltage, low-current circuit, the results do not produce hazardous energy.

Distinctive Characteristics

Extended and flush slide actuators are available.

The twin sliding contact mechanism with self-cleaning action (JSO2) provides smooth actuation and produces high contact reliability.

Gold-plated contacts prevent oxidation and sulfide effect and provide stable contact resistance.

The use of self-extinguishing UL94V-0 certified material in the cover and base provides high arc resistance and high insulation resistance.

Gull-wing terminals ensure secure PCB mounting and prevent dislodging during vapor phase and infrared convection reflow soldering.

Terminal spacing conforms to standard PCB grid:

• For JSO2: .100" (2.54mm)
• For JSO4: .050″ (1.27mm)

End-to-end stackable.

Packaged in tape-reel or stick-tube. Tape-reel packaging meets EIA-481-D Standard.

Coplanarity: all considered surfaces must lie between two parallel planes that are a maximum distance apart of .0059" (0.15mm). (Additional coplanarity details in Terms and Acronyms in the Supplement section.)
