A1211EUA-T Overview
Magnetic switches are packaged in Bulk to prevent damage. 3-SSIP packages are used for safety reasons to protect magnetic switches. For good performance, magnetic switches can supply 7.5mA as their maximum current. If these switches work, they can output 25mA as the maximum current. To make the switches work, they have 3 pins. It has 3 terminations. As a general rule, the switches should output 20mA.
