A3251LLT Overview
A protective Bulk package surrounds the magnetic switch to protect it from damage. Magnet switches are packed in TO-243AA packages for safety reasons. As a maximum current, magnetic switches can supply 7mA. A magnetic switch should only output 20mA current. The document has 3 terminations. Switches like this should supply voltages no higher than 24V. It is normal for this switch to supply 12V in order to perform reliably. This magnetic switch can provide 4.2V voltage as the minimum voltage.
