A1422LK-T Overview
An integrated magnetic switch is packaged within the Bulk in order to protect it against damage. A safety precaution is taken by putting the magnetic switches into 4-SSIP packages. In operation, these switches can output a maximum current of 25mA. These switches can supply a maximum current of 7mA. Switches are operated by 4 pins. There are 4 terminations in it. In general, the switches should output 25mA of current. When this switch is functioning, its maximum voltage should be 26.5V. The switch will normally supply 12V for reliable operation. With this magnetic switch, a voltage of 4V is the minimum voltage available. When the magnetic switch operates, it could supply 12V voltage.
