A1222LUA-T Overview
During packaging, the magnetic switch is protected against damage with the Bulk. In order to protect the switches from damage, they are packaged in 3-SSIP packages. In operation, these switches are capable of outputting 25mA as the maximum current. Switches of this type can deliver currents up to 4mA. There are 3 pins on the switches that allow them to work. In total, 3 terminations have been recorded. Current output by switches should be 25mA in general.
