A1145EUA-T Overview
Magnetic switches are packaged in Bulk for protection against damage. A safety precaution is taken by putting the magnetic switches into 3-SSIP packages. A magnetic switch can supply a maximum current of 17mA if it is well designed. To operate, the switches have a 3 pin. It has 3 terminations. If this switch is functioning properly, it should supply a voltage of 24V. For reliable operation, this switch supplies 12V voltage.
