A1121LLHLT-T Overview
A protective Tape & Reel (TR) package surrounds the magnetic switch to protect it from damage. Magnet switches are packed in SOT-23W packages for safety reasons. If these switches work, they can output 25mA as the maximum current. These switches are capable of supplying a maximum current of 4mA. 3 pins are used to operate the switches. As far as terminations are concerned, there are 3. The switches should typically output 25mA of current.
