Description

A1421LK Overview
Designed to protect magnetic switches from damage, the Bulk package contains the switches. In order to ensure safety, magnetic switches are packaged in 4-SSIP packages. In order to function well, magnetic switches should be able to supply a maximum current of 7mA. The maximum current these switches can supply when they work is 25mA. This termination has 4 terminations. Whenever this switch works, it should provide a voltage of 26.5V. This switch will normally supply 12V voltage for reliable operation. With this magnetic switch, a voltage of 4V is the minimum voltage available.
