Abstract: A latch attachment for an electromagnetically operated switching device such as a relay or a contactor. The attachment includes an adjustment means which will automatically cause a latching surface on a plunger to be engaged by a latching surface on a latch lever when the contacts of the relay are moved to their operated position by a manual force applied on the plunger.
