A1212EUA-T Overview
A protective Bulk package surrounds the magnetic switch to protect it from damage. 3-SSIP packages are used to protect the magnetic switches from damage. In order to provide good performance, magnetic switches can supply 7.5mA as the maximum current. If these switches are functioning, they can output 25mA as the maximum current. It is necessary to have a 3 pin for the switches to work. This document contains 3 terminations. Generally, switches should output 25mA current.
