Definitions

  • the invention relates to an electrical switch, in particular for a hand tool, with a manually operable pusher and a manually counteracting locking element for locking the depressed pusher, wherein the pusher along a pusher travel is displaced transversely, in particular perpendicular, to a Arretierverlagerungsweg Arresting element extends.
  • An electrical switch of the type mentioned is known.
  • This switch is used in particular in handheld power tools to control an electric drive that moves a tool of the power tool.
  • This electric switch is provided, for example, for controlling the moving speed of the tool in response to a presser travel of the pusher.
  • a locking possibility to be provided upon reaching a required for continuous operation movement speed of the tool is mounted in the machine tool such that upon reaching a predetermined switch position of the electrical switch, it is brought into operative connection with the switch (for example by gripping a recess of the switch) in order to fix it. If, for example, the maximum speed of the electric drive is required in a continuous operation, the fully depressed switch can be fixed in the depressed position by the locking element.
  • the locking element for example, a transverse to Drückerweg movable lock.
  • the locking element is designed as a manually counteracting locking element. This means that the locking element can be actuated from two opposite sides by a mirror-inverted movement.
  • Such a locking element can be operated equally well when installed in a handle by both right-handed and left-handers.
  • the electrical switch should allow easy installation and high operator comfort.
  • the electrical switch is constructed as a switch module having the pusher and the locking element.
  • a modular design also simplifies the assembly, since the switch and locking element are already pre-assembled in the module and do not have to be brought together when mounting the electrical switch. By integrating all components of the lock in the switch module results in shorter tolerance chains, since the tolerances of the power tool in the modular structure have no effect on the lock.
  • the locking element and the pusher are directly operatively connected.
  • the locking element can be in operative connection with the pusher and prevent the pusher from snapping back after actuation.
  • the switch is fixed in a corresponding position.
  • the locking element and a switching element of the electrical switch are directly operatively connected, wherein the respective position of the switching element is bound to a corresponding switching state of the electrical switch.
  • This locking can be an alternative operative connection or an additional operative connection between the locking element and the switching element, wherein the lock is connected without play directly to a part of the switch which realizes the switching - the switching element.
  • the locking element and the pusher and / or the locking element and the switching element are operatively connected via at least one intermediate element mounted in the switch module.
  • the locking element and the pusher, or the locking element and the switching element have a significant distance, occur in direct operative connection large leverage forces that lead to high material stress and an imprecise operative connection. Due to the additional storage of
  • the intermediate element is a deflecting element.
  • the deflection element may, for example, be a pivotably mounted lever which adapts the movement stroke of the locking element and the pusher or the switching element.
  • a middle position of the locking element is a release position and is manually displaceable by actuation alternatively in two opposite locking positions.
  • a so configured locking element has the advantage that it can be operated equally from two opposite sides. For actuation, for example, a pressure on a suitable location of the locking element is sufficient.
  • the locking element has a return element, which counteracts the manual displacement. If the locking element is actuated, for example, by pressure and engages in a recess of the switch, the return element can set the locking element back into the release position after the latching function has been canceled.
  • the locking element is a locking slide.
  • a particularly simple design of a locking element, which can be actuated by pressure on both sides, is a locking slide.
  • the pusher is guided through the recess-projection arrangement along the presser path when the locking element is in the release position.
  • the recess-projection arrangement allows actuation of the locking element only when the pusher is pressed. Whether the switch is locked can be recognized immediately at the trigger position - for example by pressing a button.
  • the electrical switch has an actuating element with which an end position of the pusher can be preselected on the presser travel.
