A1422LK Overview
The magnetic switch is packaged in the Bulk in order to prevent damage. In order to protect the switches from damage, they are packaged in 4-SSIP packages. Good performance is achieved by powering the magnetic switches with 7mA as the maximum current. When these switches are working, their maximum current will be 25mA. A total of 4 terminations have been reached. The maximum voltage supplied by this switch should be 26.5V when it works. It is normal for this switch to supply 12V voltage for reliable operation. Magnetic switches can supply voltages as low as 4V.
