A1121EUA-T Overview
Magnetic switches are packaged in Bulk to prevent damage. For safety reasons, magnetic switches are packaged in 3-SSIP packages. For good performance, magnetic switches can supply 4mA as their maximum current. When they work, these switches can output 25mA as their maximum current. Switches work with 3 pins. It has 3 terminations. Switches should generally output 25mA current.
