Definitions

  • the invention relates to a block-type electrical switch, especially in training as push buttons or change buttons for power tools.
  • the invention aims to provide an electrical switch for the input mentioned genus are made available, the smaller Size also works with higher nominal current with low wear.
  • an electrical switch made available in block design, which in particular as a button or change button for power tools compatible with existing switches and can be designed with one or more poles, whereby 8A ohmic and inductive load can be realized.
  • the new switch is also provided with two separate changeover contacts can be used as a brake switch.
  • the special concept with a change in the direction of action of the Shift spring and the moment switching by releasing a Swing lever intermediate stop advantageously prevents one Contact erosion by bouncing, since the moving contact on The intermediate stop is braked or stopped briefly, before closing after release.
  • the high switching energy is advantageously reduced, whereby an important contribution to reducing contact wear as well as for operating the switch with a higher one Rated current is reached.
  • the construction according to the invention advantageously also enables due to the proposed switching mechanism that with little extra effort from a push button to a toggle switch single or multi-pole version without changing the overall size becomes available.
  • the arrangement hit so that the swivel lever is a fork-shaped Recess for the passage of the tension spring when it changes the direction of action.
  • the swivel lever is a fork-shaped Recess for the passage of the tension spring when it changes the direction of action.
  • the tension spring on its other, not on the pivoted end, in a rocker arm articulated, to be acted upon by the actuator preferably to achieve a particularly compact design in the movement path of the actuating member to act on is arranged.
  • the Swivel lever at least one stop surface for an associated Intermediate stop to temporarily move the swivel lever stop provided torque switching, the torque switching then with a further pivoting of the tension spring through their dead center position after removing the intermediate stop he follows.
  • the intermediate pivot lever stop is preferably with a side movable out of the movement path of the pivot lever Element formed. This moving out of the element can be done by a rotary movement and / or pivoting movement and / or pushing movement be made depending on the movement of the actuator for the intended torque switching.
  • Swing lever intermediate stop on a yoke-shaped Element provided by the actuator laterally is movable away from the stop surface of the pivot lever.
  • the Coupling the movement between the actuator and movable Stop can be done according to various mechanical principles be made. It is particularly simple and compact a solution in which the actuator with the intermediate stop element, especially in its yoke-shaped design, is connected via a link control. Thereby can be an extraordinarily compact, part and Realize low-wear, functionally optimized solution.
  • this is Actuator designed as a button or as a change button, who works against a compression spring and directly on one Rocker arm attacks.
  • FIG 1 is a first embodiment of an inventive electrical switch shown as a button 10.
  • the Button 10 has an actuator selected as a slide 11 on that on a rocker arm 12 in its pivoting direction attacks, and which at 13 in the manner shown the pivot pin assembly stored in the housing, not shown is.
  • the actuator 11 is counter its direction of actuation is acted upon by a compression spring 14, which is represented in a similar way with its other end Supported on the housing.
  • the end of the rocker arm 12 facing away from the pin arrangement 13 has molded on both sides transversely to its management level Arms 14 and 15, the articulation mounts 16 and 17 for the articulation a tension spring 18 or 19 (see Figure 4).
  • the other end of the tension spring 18 or 19 is on a pivot lever 20, or in the tension spring 19 on a pivot lever 21, near the movable switch contact 22 in the area of the front Articulated end of the pivot lever.
  • the pivot lever 20 widens behind the articulation point the spring 18 or 19 towards its other end in two spaced legs 23 and 24, the end of each in one Swivel bearing receptacle 25 or 26 fixed to the housing is kept loose is.
  • the distance between the legs 23 and 24 and Swivel bearing mounts 25 and 26 is for loose passage the tension spring 18 or 19 formed, that is larger than the tension spring diameter.
  • the pivot levers 20 and 21 by the Tension spring 18 or 19 in the pivot bearings 25 or 26 for the intended Swivel are supported, as is the case fixed Connection 27, at the upper end of the pivot bearing 25, 26 are formed from an electrically conductive material.
  • An electrical fixed contact 28 is not shown in FIG Way fixed for contacting the movable switch contact 22 in a plane below the pivot bearing 25 and 26 arranged and electrically to the outside (see Figure 4) for connecting an electrical conductor and fastening it guided by a screw 29.
  • slide 30 designates a yoke-shaped slide, which extends transversely to the pivot plane of the rocker arm 12 and is penetrated by this in a recess 31.
  • slide 30 is in the housing 32 out several times and has according to Figure 6 on the back integrally formed inclined sliding surfaces 38 and 39, respectively, for switching on a provided on the actuator 11 pin 40 for Transverse displacement of the slide 30 when the actuator is actuated 11 engages the sliding surface 38.
  • an integrally formed slope on the actuator 11 Sliding surface 41 is provided, which on the inclined sliding surface 39th of the slider 30 for transverse displacement in the opposite Direction attacks.
  • the slider 30 has on both sides of the recess 31 laterally open recesses 33 and 34, respectively, leading to the edge of the slide 30 transition into intermediate lever stops 35 or 36.
  • Figure 4 shows a two-pole push button with lower housing part 32, in which two parallel buttons with swivel levers 20 and 21 are provided, which are initially via the rocker arm 12 to Intermediate stop 35 or 36 moves and then after transverse displacement the slider 30, the stop surfaces of the pivot lever release.
  • Figure 5 shows another embodiment of the switch in training as a single-pole switch.
  • the modification is that a second fixed contact 28 'is provided and the pivot lever 20 between the illustrated Switch-on position after release by the intermediate stop 35 to the fixed contact 28 'after contact with the intermediate stop 35' In the upper area of the slider 30, it can be activated with little bounce is.
  • the control of the slide 30 by the actuator 11 is provided so that when the rocker arm is pivoted downward 12 first the intermediate stop 35 in the movement path the pivot lever 20 is located, then moved is that the pivot lever 20 in the recess 33 for closing contact can occur.
  • the rocker arm back 12 from the position shown in FIG Swivel lever 20 first between stop 35 'and then the slider 30 to the right in FIG Torque switching of the movable contact to the fixed contact 28 'moves.
  • the described sliding movements of the slide 30 are in Figure 5 with A (momentary switching to fixed contact 28) and B (Torque circuit to the fixed contact 28 ').
  • the reference number 36 ' indicates one intermediate stop surface on the other Side of the slide 30 on, for the formation of a two-pole Change button is provided in which a pivot lever 21 is provided, just like the pivot lever 20 of Figure 5 has reciprocal, movable contacts 22 and 22 ' and against a second fixed contact, not shown, on the top is working.
