                                                A1213LUA-T Overview
A protective Bulk package surrounds the magnetic switch to protect it from damage. For safety reasons, magnetic switches are packaged in 3-SSIP packages. When operating, these switches can output a maximum current of 25mA. There is a maximum current that can be supplied by these switches of 7.5mA. Switches work with 3 pins. The file has 3 terminations. Switches should generally output a current of 20mA. It is possible that the magnetic switches can supply 5V voltage when they are in operation.
