Abstract
An electrically operable strike with a pivotable keeper and a rectilinearly slidable locking member with planar major surfaces with arms extending parallel to the surface planes, which arms in one position of the locking member prevent pivoting of the keeper and which in a second, different position of the locking member, permit the keeper to pivot. The locking member has a magnetic portion and is moved from one position to the other by the magnetic field of an electrically energizable coil having its axis perpendicular to the plane of movement of the locking member. There are two similar locking members, and with one locking member, the strike is normally locked and by replacing such locking member by the other locking member, the strike is normally unlocked. In one embodiment, the keeper engages faces of the locking member arms and in another embodiment, the keeper engages faces at the ends of the locking member arms. By inverting the strike and moving the coil to the opposite end of the strike, the "hand" of the strike can be changed.
