A1147LLHLT-T Overview
The magnetic switch is packaged in the Tape & Reel (TR) to ensure it is protected against damage. SOT-23W packages are used for safety reasons to protect magnetic switches. A good performance can be achieved with magnetic switches that can deliver 17mA as the maximum current. For the switches to function, there are 3 pins. The file contains 3 terminations. Switches like this should supply voltages no higher than 24V. In terms of reliability, this switch will normally supply 12V.
