  • a ratchet mechanism is released from the trigger unlatches, and the contact opening usually takes place via a toggle lever system, which in Connection with further levers and tabs on the movement of the key switch transfers the contact pieces and opens them permanently.
  • the toggle system is through an actuating element via a translatory movement (push button), via a Rotating or tilting movement (rotary knob, shift lever) moves and into an over-center position brought.
  • This movement of the toggle system which is usually An energy store is tensioned via the clinker mechanism.
  • This pawl mechanism acts on transmission parts and thus on the contact point arrangement.
  • the latch mechanism is triggered unlatched by overriding the support of a jack so that the toggle lever system can collapse.
  • the key switch acts on the collapse of the toggle lever system due to the spring force in an opening manner.
  • the actuator is automatically returned to the original position (Off position) the clinker mechanism is activated again, so that the Switch lock can be switched on again.
  • the key switch can hold trigger the actuator in the on position unaffected. With contact welding the actuator must not get into the out position and the operator show a contact opening.
  • a switch lock with rotary drive is known from EP 0 612 089 A2. Via the control panel is a deflection of the axis of rotation via two rotatably mounted parts with bevel gear reached by 90 °.
  • the second swiveling part with bevel gear contains a banana-shaped one Recess that moves the toggle.
  • the energy accumulator becomes a toggle lever on a pawl when the key switch is switched on tensioned with two compression springs and via a lever mechanism with contact carrier part the contact apparatus is closed or the device is switched on.
  • switching off the switching mechanism is released from the switching mechanism via a sliding mechanism, so that the opening of the contact point arrangement or switching off suddenly he follows.
  • a switch lock has become known, which both can be switched on by pressing a button or via a rotary actuator.
  • the Switch lock is switched on via a rocker, which is a lever of the knee lever system is.
  • This rocker is switched on by a button and by another Key to switch the key switch moved.
  • the rocker is used for the rotary drive by turning the axis of rotation by 90 ° using additional parts.
  • the object of the invention is to provide a switch lock of the type mentioned, in which the number of parts is reduced compared to the known arrangements and also the mechanical load and thus the wear of the Switch lock can be reduced.
  • the arrangement is said to be a snap mechanism act especially when switching off, so that switching off erratic he follows.
  • the switch lock has a first lever on its one End rotatably mounted, a second lever with one end the other end of the second lever is rotatably connected and part of the latching point forms, with both levers approximately parallel to each other and approximately perpendicular to the direction of force of the trigger, and the other end in the area of fixed bearing of the first lever is mounted on a bracket, and a third lever, which is rotatably mounted at one end and the other End forms the other part of the latching point.
  • the main advantage of this arrangement is that the number of parts reduced and the wear of the individual parts is also reduced, so that the risk of so-called snap-through no longer exists.
  • an interlocking point and the trigger can be provided with a rotatably mounted connecting element, that in the locked state the first and thus the second lever in the latching point holds and when triggered the second lever to open the latch releases.
  • the connecting element can be permanently held in the direction of retention by means of a spring be charged.
  • a holding surface on the connecting element molded on, which cooperates with a support surface on the first lever in the switched-on position, when released, however, comes free from the support surface and releases the first lever.
  • the tab at the end at which it is connected the intermediate lever is connected have a nose with a projection on Bracket interacts so that when the tab is pivoted, the bracket pivoted.
  • Fig. 8 shows a switch 10 from the side, the output at 11 with a first arm 12 of an L-shaped rotary lever 13 is coupled, the second arm 14 acts on a contact carrier 15, on which a contact bridge 16 is attached, the carries two movable contact pieces 17 and 18.
  • the movable contact pieces 17 and 18 cooperate with fixed contact pieces 19 and 20 on arc guide rails 21, 22 are attached.
  • the arc guide rails 21, 22 do not limit Arc bundle sheet packets shown in detail and are used to the fixed Contact piece 19 or 20 arising arc base in the arc quenching plate package respectively.
  • the L-shaped rotary lever is movably and rotatably mounted at 23; the first arm is 12 acted upon by a compression spring 24 such that the pressure spring 24 the rotary lever tries to pivot clockwise in the direction of switching off, so that the second arm 14 can hit a shoulder 25 on the contact carrier 15 as soon as the switch lock has released the first arm 12.
  • Fig. 7 shows the off position: The Compression spring 24 has pivoted the rotary lever so that the second arm 14 on the paragraph 25 open and the contact carrier 15 together with the contact bridge 16 in Can bring off position.
  • the switch lock 10 is, as can be seen from FIG. 6, received in a switch lock carrier 26. It has a receiving space 27 in which the switching lock is inserted.
  • FIGS. 1 to 5 Reference is now made to FIGS. 1 to 5.
  • Fig. 1 shows the switch lock in the on position. It has a first lever 30 which has an approximately banana-shaped contour and fixed at one end at 31 is rotatably mounted. The other end of the first lever 30 is via a joint 32 hingedly connected to a second lever 33, which partially covers the first lever 30. On this second lever 33 there is a nose 34, which is shown in further below described forms part of a latching point. The other end of the second lever is rotatably supported at 35 with an approximately U-shaped control lever 36, the other end of which is pressed by a compression spring 37 against a projection 37a becomes.
  • the two levers 30 and 33 run approximately parallel to one another.
  • a support lug 38 is formed, which is supported against a support surface 39 of a rotatably mounted rotating part 40, which rotating part 40 has an attack area 41 on which a thermal or can attack electromagnetic trigger element and the rotary member 40 clockwise pivoted.
  • the rotating part 40 is opposite Turned clockwise, so that when the triggering ends in the in Fig. 1st drawn position can be moved back.
  • the switch lock also has a third lever 43, which is bent approximately L-shaped and its first leg 44 on the diametrically opposite to the rotating part 49 Side is rotatably mounted at 45.
  • This first leg 44 runs approximately parallel to the first and the second lever 30, 33.
  • perpendicular to the first leg 44 is a second leg 46 connected, the free end of a support surface 47 for the nose 34 forms.
  • a toggle lever arrangement is articulated approximately in the middle of the second leg 46 48 connected with two tabs 49 and 52, the first tab 49 articulated with its free end at 50 on the second leg 46 and with its other End at 51 is hinged to the second tab 52. Shown in Fig.
