Reference: SMT TR

Condition: New product

Surface mount tiny washable rocker switches, single pole configurations.

Main features

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
Distance between case and circuit : 0.55 mm (.021) End stackable with 10.16 mm (.40) pitch
Available with positioning pins to ensure switch orientation during the reflow process and increasing switch mechanical resistance
Protected against electrostatic discharges (ESD) up to 10 KV
Washable : Construction withstands cleaning processes, including hot water under pressure
