This invention is an improved switch cabinet latch of the type having a cabinet body and a cabinet door hinged to it with the door held in closed position by means of a push-rod lock on the cabinet door with push rods movable axially by rotational movement of an actuating element such that in the closed position closing ends on the push rods which face away from the push-rod lock reach behind closing faces mounted on the cabinet body while in the open position they move away from the closing faces. By virtue of the special configuration of the ends of the push rods and lock blocks mounted on the cabinet body, an improved clamping of the door to the cabinet body is achieved in combination with a hasp of the push-rod lock in the closed position. This clamping is initiated in forced sequence by two steps in the rotational movement of the actuating element of the push-rod lock.

In a switch cabinet latch of the type having a cabinet body and a door hinged thereto which may be held in closed position by a door-mounted push-rod lock along a closing edge, the lock having push rods extending therefrom and an actuating element which when rotated moves the push rods axially, the push rods having closing ends which in the closed position reach behind closing faces mounted on the cabinet body and in the open position are away from the closing faces, the improvement comprising: rollers rotatably mounted on the closing ends on the push rods; lock blocks mounted on the cabinet body, each block having one of said closing faces substantially parallel to the door and facing away therefrom and a transition surface at an acute angle to the direction of push-rod movement facing away from the cabinet door, such that turning of the actuating element moves the rollers from the open position first against the transition surfaces to impart a closing movement to the door and then onto the door-parallel closing faces; the closing ends having lock surfaces inclined toward the door in position to cooperate with the closing-block transition surfaces to clamp the door against the cabinet body; a holding block mounted on the cabinet body; and a hasp on the actuating element with a locking nose extending radially therefrom positioned such that further turning of the actuating element, with said rollers already on said door-parallel closing faces, moves the locking nose behind the holding block to clamp the door to the cabinet body in the area of the push-rod lock.
