SMT TR series
Surface mount tiny washable rocker switches
Distinctive features and specifications
❑
Entirely designed for surface mount
❑
Tape and reel packaging
❑
Reflow solderable
•
High temperature plastic materials
• Tin plated ground plate
• Terminal coating : tin alloy over nickel plating
• Terminals turned to the outside, preventing the shadow effect in infrared soldering
and permitting visual inspection of solder joints
