Abstract

A device is described on a double switch rocker (1) of an electric switch which is characterized in that, on the underside (9) of the upper part (4) of the housing, four molded tenons (11) form a square at the level of the passages (10) for the sockets (3) of the switch rockers (1), on which a plastic element (12) can be pressed using four sockets (13) having an arrangement corresponding to the arrangement of the tenons, with a clamping effect, the plastic element also forming, by means of spring bars (14) molded in the shape of an arc and arranged on the sockets, two guide slots (15) opposite in which is introduced, when placing the upper part (4) of the housing on the lower part (8), the side walls (16) molded on the sockets (3) of the switch rockers, thus forming an active connection with the switch rockers (1).

Description

The invention relates to a device on a double switch rocker,

with spring slides

  of contact in sockets of the switching rockers

  in the upper part of the housing of a

  electric mutator for pushing in and operating

  of a switch flip-flop with contactors on each side of the flip-flops to establish contact with corresponding contactors arranged in the lower part of the housing and to return the switch flip-flops to their starting position

after each insertion.

  By German patent 1 238 537, an electrical switch is known which has a push button for establishing a contact, held upwards using

  of two half-shaped contact spring arms

  Moon. The ends of these contact spring arms are provided with a contactor. When the push button is actuated by pushing it in, the arms of the contact spring are compressed and their contactors thus simultaneously come into contact with connectors correspondingly arranged in the housing.

  for the duration of the actuation.

  In addition, from the German document 2 060 752, a pusher is known whose actuating member is

  returned to its starting position after each action

  using a spring. The actuator is

  equipped with a slide which acts, during the action-

  ment, on a switch rocker subjected to the effect of a spring, a contact rocker, equipped with a contactor, then comes into contact, in one or the other switching position, with the connectors

  in the housing. This switching mechanism does not

  comes, however, only for the operation of a push-

  evening. On the other hand, from document DE-24 02 613 B, another pusher is known, the actuating member of which can also be executed in the form of a pusher.

  double rocker with a rocker divided into two parts

  ties. From this state of the art, the object of the invention resides in the development of a switch

  using the parts of a usual pusher and a

  positive double toggle switch, which resets the

  switches to the starting position after an action

  of the switch without the usual return spring.

  This problem is solved according to the invention in that, on the underside of the upper part of the

  case, four molded studs form a square at the

  calf of the passages for the sockets of the rocker switches, on which one can push a plastic element using four sockets having a provision corresponding to the arrangement of the tenons,

  with a clamping effect, the plastic element

  mant also, using spring bars molded in the shape of an arc and arranged on the sockets, two

  opposite guide slots into which are inserted

  duit, when placing the upper part of the housing on the lower part, the molded side walls

  located on the sockets of the rocker switches

  tor, thus forming an active bond with the rockers

  the switch. Advantageous forms of execution

  of the invention are the subject of the second claims

  daires. The invention is explained below using an exemplary embodiment shown in FIGS. drawing. Fig. 1 shows a back view, schematic, in perspective and in the order of disassembly of a double rocker switch and the upper part of the housing with the pins

  reception for the device according to the

  vention, in the form of a plastic element

than,

  fig. 2 shows in perspective the upper part

  of the housing according to fig. 1 complete-

mentally raised,

  fig. 3 shows in perspective the lower part

  lower of the housing with an electric strip

  that and the support positions for two contact scales as well as the corresponding contactors and

  fig. 4 shows fig. 3 in exploded view.

  According to the representation in the drawing, a double

  switch rocker 1 is equipped, for each low-

  cule, of a switch rocker socket 3 in which is housed each time a spring-loaded contact slider 2. Each switch rocker socket 3

  is provided with a side wall 16 directed towards the interior

  laughing in such a way that these are diametral-

  opposite. When mounting on the upper part 4 of the housing, the double switch rocker 1 crossbeam, with its sockets 3 of switch rocker,

  the passages 10 of the upper part of the housing.

  As can be seen in fig. 1 of the drawing, the underside of the upper part 4 of the housing is fitted, at the passages 10, with four molded studs 11 which form a square between them. In addition, there is also shown in FIG. 1 in perspective the device according to the invention in the form of a plastic element 12. This element consists in particular

  by four sockets 13 whose arrangement and distribution

  tance with respect to each other correspond to the

  arrangement of the four tenons 11 of the upper part

  lower 4 of the housing. In addition, the plastic element 12 has at each bushing 13 molded spring bars 14 in the form of an arc which are arranged relative to each other so that their ends form, on the sides facing and outward, guide slots 15, the lateral sides of which are marked with 17. The lateral walls 17 have an elastic spring effect thanks to their embodiment in the form of an arc. The spring-loaded elastic spacing of the side walls 17 is limited thanks to

  a cross member 20 located between the ends of the bars-

  your spring 14, which each form a guide slot 15. By placing the plastic element 12 with its sockets 13, by clamping effect, on the pins 11 of the upper part 4 of the housing, the device is formed according to the invention enabling contact to be made in an electrical switch. In the clamped position of the plastic element 12, its slots

  guide 15 surround the side walls 16 of the bushings

  the 3 of the switch flip-flops and therefore form a

  active link with double switch rocker 1.

  When a rocker switch 1 is actuated in either contact position, the wall

  side 16 compresses the switch rocker socket 3

  corresponding clamp on one or the other elastic spring wall 17 of the guide slot 15, so that after each depression, the force exerted on the corresponding wall 17 serves as a restoring force for the switch rocker in its starting position. During the insertion, the slide at

  contact spring 2 of a rocker 1 acts on a rocker

  contact shoe 5 correspondingly disposed on the lower part 8 of the housing for the duration of the insertion and actuates by a tilting the contact lever in the tilting support 18, which

  then comes into contact with one of the contacts 6 of the

  corresponding tactor 7 in the lower part 8 of the housing. Correspondingly to the double rocker

  switch 1 in the upper part 4 of the box

  tier, the lower part 8 of the housing has two contact rockers 5 on two tilting supports 8 which are electrically connected to a strip 19. The contactors 6 on each side of the contact rocker

  correspond each time to a 7-way contactor

  dant arranged in the lower part of the housing.

  The other parts shown in the drawing, without reference, do not concern the invention and do not

are therefore not described.
