A1421LK-T Overview
The magnetic switch is packaged in the Bulk to prevent damage. In order to ensure safety, magnetic switches are packaged in 4-SSIP packages. If they are working properly, these switches can output a maximum current of 25mA. Currents up to 7mA can be supplied by these switches. In order for the switches to function, they have 4 pins. The file contains 4 terminations. The switches should typically output 25mA of current. If it works properly, this switch should produce a voltage of 26.5V. It is normal for this switch to supply 12V in order to perform reliably. Magnetic switches can supply voltages as low as 4V. When the magnetic switch operates, it could supply 12V voltage.
