A1222EUA-T Overview
The magnetic switch is packaged in the Bulk in order to prevent damage. To ensure safety, the magnetic switches are packaged in 3-SSIP packages. As a maximum current, the magnetic switches can supply 4mA. When these switches are working, 25mA is the maximum current they can output. There are 3 pins on the switches that allow them to work. This has 3 terminations. It is generally recommended that the switches output 25mA current.
