APEM SMT-TR Rocker switches

SMT TR Series Rocker

APEM SMT TR series surface mount tiny washable rocker switches, single pole configurations.

They are entirely designed for surface mount applications. Tape and reel packaging. Reflow solderable. Designed with high temperature plastic materials. Tin plated ground plate Has a 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.
