A3425EK-T Overview
Magnetic switches are packaged in Bulk to prevent damage. For safety reasons, the magnetic switches are packaged in 4-SSIP packages. For good performance, the magnetic switches can supply 6mA. The maximum current that can be output by these switches is 20mA. Switches work with 4 pins. A total of 4 terminations have been reached. Switches should generally output a current of 70mA. In order for this switch to function, its maximum voltage should be 18V. For reliable performance, this switch usually provides 12V voltage. A magnetic switch can supply a voltage as low as 3.3V.
