Device for setting one from an overlying side of the rocker beyond the dead center normally open contact piece, a break contact piece 5 arranged in a line, the relay works with self- and a changeover contact block existing, d, h. to unlock this addressed changeover contact arrangement From self-locking a relay, made of insulating material, acts on automatic resetting by adjusting the spring-loaded, externally operated push button normally open contact and with means to the Aul: - button on the seesaw until the lifting of the self-locking, especially for thermal rocker, is pushed beyond the dead center line. Speaks mixed protective relays, whereby the means switches the relay on again during this reset movement, to cancel the self-locking, of one so can indeed through the bimetal or the intermediate adjustable and lockable closing conlact member, the rocker is separated from the break contact piece are formed according to patent 1 563 670, but a closing of the closer is characterized that the normally open contact is not possible because the reset button contact piece (2) on which the contact point a skipping of the rocker over the dead center is opposite Side under spring pressure prevents. A free release for the normally open one slidable plunger (6) rests, which is in the contact piece in this known arrangement Contact area with an inclined surface (10) in front therefore not available. Working by the turnkey is. for example on the shunt release of a self- 2. Device according to claim 1, characterized by a switch, so in this case no triggering is possible indicates that the plunger (6) is carried out by one of what may result in the destruction of a can result in externally rotatable eccentric (11) in the final entire system. Such Positions can be brought. Disadvantages are admittedly due to the subject of the 3. Device according to claim 2, thereby avoiding 25 main patents, but the ankennzeichnci here that the eccentric (11) plane given means are still relatively expensive.
Surface parts (14, 20) are provided, which in the The invention is based on the object of the end positions of the plunger (6) on the uniform object of the main patent, in which a free protrusions (21) of the plunger (6) rest. Triggering for the normally open contact piece at low 4. Device according to claim 2 or 3, as- 30 like actuating force requirement for the changeover contact, characterized in that the eccentric (11) arrangement is given, with regard to the simple disk-shaped design ? N one end of a space-saving structure to further improve the housing of the device penetrating, The device should be easier and safer to use bolt-shaped part (15) is attached, on the other end of which a pointer part (17) should be provided. 35 stand to be able to recognize the position of the device from the outside through an adapted housing opening (19) without further ado. The invention is feasible. is characterized in that the normally open Kontaktscück at the opposite of the contact point Page under Fed \ .rprint on a ver 40 slidable plunger rests, which is in the contact area with is provided with an inclined surface. Unintentional insertion of a self-locking slide and associated, possibly uncontrollable The subject of the main patent is a device. Intermediate positions of the device are avoided for setting one of a normally open contact if the plunger can be brought into the end positions by an externally rotating piece, an opening contact piece and a reversible eccentric. Switching contact piece existing changeover contact- This also has the advantage that the possibility of arranging self-locking to automatic return is available, the actuation of the eccentric, for example position by adjusting the normally open contact piece from the outside, only by a screwdriver and with means to cancel the self-locking. 5 » slot 2: u enable. Compared to the adjustment, especially for thermally operating protective relays, a screw, the eccentric position has the advantage, whereby the means for canceling the self-locking only have to be adjusted by a certain degree of angle by an adjustable and lockable closer. and not by several threads, contact piece are formed. The formation of the adjustment slot as a pointer is With this proposed device, a 55 was thus easily possible. Defined end positions of known protective relay (SSW publication 444 / 224b: for adjusting the eccentric or for the ver-1641. TS 652, 1964) improved, in which the closing sliding path of the plunger results if the eccentric contact piece is designed as a screw, through the flat surface parts are provided which, when they are rotated, switch the relay from end positions of the plunger to uniform pre-automatic resetting to self-locking before jumps of the plunger. A simple attachment can be made. The known arrangement of the eccentric on the housing of the device leaves a rocker seated on which a dead center spring acts. they achieve '· «in that the eccentric washer-When the relay is triggered, the bimetallic strips act in the shape of one end of a bolt-shaped member that penetrates the housing either directly or via a resilient intermediate member on the rocker or they move the bearing. 63 Part is attached, at the other end of which a pointer point of the rocker or the suspension point of the dead part is provided, which is provided by an adapted point spring. The normally open contact piece is thus located. housing oiling is feasible.
