A3281ELT Overview

For protection against damage, the magnetic switch is packaged in the Bulk. TO-243AA packages are used for safety reasons to protect magnetic switches. A magnetic switch is capable of supplying 8mA as the maximum current for maximum performance. Switches of this type are capable of delivering 25mA as the maximum current when they are in use. To make the switches work, they have 4 pins. The file contains 3 terminations. Normally, this switch will supply 12V voltage for reliable performance.
