Definitions

  • the invention relates to an electrical switch according to the preamble of patent claim 1.
  • Such switches are used for electrical appliances.
  • these are power tools, such as hand-held power tools such as electric drills, rotary hammers, impact hammers, chisel hammers, electric screwdrivers, angle grinder o. The like.
  • These switches are often installed in the handle of the power tool.
  • the invention has for its object to develop the switch so that it is suitable for use in slim handles of power tools.
  • a switch with an extra slim switch profile for use in mains and / or battery-powered rotary hammers, impact hammers and / or combi hammers are to be created, which have a very slim spade handle, which is preferably gummed for vibration damping.
  • the actuating slide and the slide switch in the direction of movement behind one another and thus in particular substantially in series with respect to the direction of movement are arranged to each other, whereby the switch has a very flat design.
  • a switch such as a hammer switch, with a tease Moderator switching system, with a slim switch body and / or plug-blockable electrical connections. Because in the latter case all
  • Connections for the switch are located on the same side, the cables no longer have to be guided past the switch body, which further contributes to the slenderness. Further embodiments of the invention are the subject of the dependent claims.
  • the slide switch can be substantially linearly movable in the direction of movement.
  • the actuating slide can also be movable in the direction of movement, in particular substantially linearly movable.
  • the switch has a, for example, a base and a lid existing, housing.
  • the actuating slide and the slide switch are then in the housing, which are movably mounted in the housing.
  • the elastic means may consist in a cost effective manner of a compression spring in the manner of an acceleration spring.
  • the one end of the acceleration spring with the slide switch and the other end of the acceleration spring interact with the actuating slide for switching the slide valve between the two positions alternately according to the respective position of the slide switch.
  • an acting between the actuating slide and a stop in the housing return spring is arranged in and / or on the actuating slide.
  • the return spring serves to return the operating slide and thereby also the slide switch from one position to the other position.
  • the stop for the return spring is located in the base of the housing.
  • the actuator may be pivotally mounted on the housing. In a compact manner, it then makes sense that a toggle pivotally mounted on the housing both on the actuator and on Actuator is articulated. With the help of the toggle lever of the actuating slide is movable by the pivoting movement of the actuator substantially linearly in the direction of movement.
  • the contact system in a simple embodiment, two fixed contacts and a configured in the manner of a contact bridge switching contact.
  • the contact bridge is arranged by means of a contact spring elastic on the slide switch.
  • the fixed contact is the front side of the housing, in particular upright, arranged.
  • an electrical connection is from the fixed contact.
  • the connection is guided on the front side of the housing to the outside. Preferably, this applies to all connections, so both for the power / battery connection and for the motor connection. Since thus the motor and power lines are located on one side of the housing, thereby a plug block for the electrical leads for the "outside" -Contacting of the contact system at the terminal in a simple manner can be plugged.
  • the locking means consists of a, in particular approximately U-shaped designed detent spring and a cooperating with the detent cam.
  • the detent spring can be fixedly mounted in the base. The cam can then be located on the slide switch, whereby the detent spring acts to support the slim design essentially to "inside".
  • the detent spring can also be arranged to the effect of "outside”.
  • the locking means instead of a detent spring and the locking means consist of at least one spring-loaded ball, in turn, the ball cooperates with a corresponding cam.
  • the electrical switch is particularly suitable for an electrical appliance, in particular for a power tool that carries out vibrations in a direction of impact.
  • the switch is arranged in the electrical appliance such that the direction of movement is substantially perpendicular to the direction of impact. In this installation position a teaser of the switch is largely prevented.
  • the arrangement for the switching system is designed so that results in a very slim, elongated design. This makes it possible to design ergonomically and mechanically optimal handles for the power tool. Also slim handles with reinforcing ribs for stiffening and a soft component for vibration damping are made possible.
  • the switching system is not teasebar in ON and / or OFF position due to the snapping switching characteristic.
  • the switch will preferably be installed in the power tool such that the contact opening is perpendicular to the direction of impact of the machine, which is the ideal case. Thus, the risk of lifting the contacts due to strong vibration is eliminated or at least reduced.
  • All electrical connections of the switch namely the mains / battery and motor connections, are on one side, for example four flat plugs of 4.8 mm or 6.3 mm width are used as connection. However, it can also be a corresponding switch with female terminals, for example, for the power socket terminals and for the motor terminal flat plug, or even a switch with screw terminals.
  • Such a switch can thus be provided with a rocker for a bistable switch.
  • the switch has small dimensions with high electrical performance.
  • the machine manufacturers for the power tool can thus make the handle shell slim, robust and / or ergonomic. This is possible thanks to the extra slim switch profile and / or the connection way for the switch.
  • the switching system is not teasebar due to its snapping switching characteristic. This is supported by the arrangement of the switch with its contact opening perpendicular to the direction of impact, which represents the Hauptvibrationsraum. It is possible to connect through a connector block, as all connections are on one side. As a result, the lines for voltage supply and / or voltage discharge do not have to be led past the housing of the switch, thus enabling a slim profile for the switch.
  • Fig. 1 is an electric switch 1 in monostable design for power tools, such as drills, rotary hammers, impact hammers, chisel hammers, angle grinder o. The like.
  • the switch 1 has a housing consisting of a base 3 and a cover 4 2.
  • an actuator 5 is rotatably mounted and thus pivotally mounted.
  • the actuator 5 is used for switching action on a befindliches in the housing 2 contact system 6 (see Fig. 3 ).
  • the contact system 6 comprises at least one fixed contact 7 and a switching contact 8.
  • the switching contact 8 is designed in the manner of a contact bridge and acts with two fixed contacts 7, 7 'together.
  • the switching contact 8 is supported by a movable between two positions slide switch 10 by the contact bridge 8 is arranged by means of a contact spring 9 on the slide switch 10. In one position, the switching contact 8 is away from the fixed contact 7, 7 ', which is the off-switching position, and in the other position, the switching contact 8 is located on the fixed contact 7, 7', which is the input Switching position is.
  • the two-pole contact system 6 also comprises a second contact bridge 8, which in turn interacts with two fixed contacts 7, 7 '.
  • the slide switch 10 is coupled by means of an elastic means 11, namely a compression spring in the manner of an acceleration spring 11, with an actuating slide 12.
  • the acceleration spring 11 is arranged in a frame-like recess 24 in the slide valve 10. This can alternately according to the respective position of the slide valve 10, the one end of the acceleration spring 11 with the slide switch 10 and the other end of the acceleration spring 11 with the operating slide 12 to switch the switching slide 10 cooperate.
  • the actuating slide 12 is in turn movable by the actuator 5 by the actuating slide 12 is coupled by means of a toggle lever 13 with the actuator 5.
  • the toggle lever 13 is rotatably supported by a pin 27 on a pivot bearing 26 on the cover 4 of the housing 2.
  • the toggle lever 13 is articulated by means of a tubular rivet 14 on the actuating member 5 and extends from a bellows-type seal 15 sealed into the housing 2 inside.
  • the toggle lever 13 is articulated by means of a fork-like pliers 28 on the actuating slide 12.
  • the actuating slide 12 and the slide switch 10 are arranged one behind the other in the direction of movement 29, namely substantially in series with respect to the direction of movement 29, so that the switch 1 has a very flat design.
  • Fig. 5 such as Fig. 6 can be seen, so that the slide valve 10 is arranged in the actuating slide 12 such that the slide valve 10 is partially covered by the actuating slide 12.
  • the actuating slide 12 and the slide switch 10 are located in the housing 2, in the base 3 linearly movably mounted. Furthermore, the fixed contact 7, 7 'in the direction of movement 29 in series with the actuating slide 12 and the slide valve 10 is located.
  • Fig. 3 the fixed contact 7, 7 'frontally disposed on the housing 2, wherein an electrical connection 18 from the fixed contact 7, 7' goes off.
  • the terminal 18 leads in the manner of a tab at the front of the housing 2 to the outside, as shown by Fig. 2 can be seen.
  • a plug block for all electrical leads to the switch 1 in the manner of an "external" -Kontakttechnik at the terminals 18 can be plugged.
  • the power connection for the switch 1 is realized by socket terminals 19, while the motor connection to the switch 1 again consists of flat plugs 18.
  • the mains connection consists of screw terminals 20.
  • Fig. 9 a switch 1 with bistable switching function shown.
  • the rocker 5' remains even after their release by the operator in the on-switching position.

  • the latching means 16 consists of a detent spring 21 and a cooperating with the detent spring 21 cam 22.
  • the detent spring 21 is configured in approximately U-shaped and fixed in the base 3.
  • the cam 22 is located on the slide 10. Since the action of the detent spring 21 is directed inwardly due to this arrangement, a further contribution to the narrow design of the housing 2 is made by this measure.
  • the locking means may also consist of at least one spring-loaded ball and a cooperating with the ball cam, which is not shown further.
  • the installation should be such that the contact opening of the contact system 6, that is, the opening in the direction of movement 29 for the contacts 7, 7 ', 8, directed substantially perpendicular to the direction of impact 30 of the power tool, which is the main vibration direction for the power tool is.
