ABSTRACT:
A means for physically opening and closing electrical contacts to check their integrity for safety systems is provided. Contact means are cycled by the movement of two relatively moveable parts and the actual physical operation of the contacts is checked. The system is latched in its operable position by reversing the energization of an electromagnet which was used to unlatch or start the checking sequence.
