A1222LLHLT-T Overview
A magnetic switch is packaged in the Tape & Reel (TR) to prevent damage. For safety reasons, the magnetic switches are packaged in SOT-23W packages. In operation, these switches can output a maximum current of 25mA. They can supply up to 4mA amps of current. Switches require 3 pins to function. 3 terminations are contained in it. There should be 25mA current output from the switches in general.
