                                                APS11205LUAA Overview
For protection against damage, the magnetic switch is packaged in the Bulk. For safety reasons, the magnetic switches have been packaged in 3-SSIP packages. In order to be effective, magnetic switches can provide a maximum current of 4mA. If magnetic switches are to be output, the maximum current should be 5mA. There are 3 terminations in it. In a working switch, the maximum voltage should be 5.5V. It is normal for this switch to supply 5V voltage for reliable operation. A magnetic switch can supply a voltage as low as 2.8V.
