A1142LUA Overview
This Bulk package protects the magnetic switch from damage. 3-SSIP packages are used for safety reasons to protect magnetic switches. It contains 3 terminations. If this switch is functioning properly, it should supply a voltage of 24V. This switch will normally supply 12V voltage for reliable operation. With this magnetic switch, a voltage of 3.5V is the minimum voltage available.
