A1425LK Overview
A protective Bulk is applied to the magnetic switch in order to prevent damage. The magnetic switches are put into 4-SSIP packages for safety protection. A magnetic switch is capable of supplying 7mA as the maximum current for maximum performance. In operation, these switches are capable of outputting 25mA as the maximum current. To make the switches work, they have 4 pins. 4 terminations are contained in it. Switches should generally produce 25mA current. In order for this switch to function properly, it should supply a voltage of 26.5V. Normally, this switch will supply 12V voltage for reliable performance. Using this magnetic switch, you can supply 4V at the minimum.
