Definitions

  • the invention relates to a device for the input and Switching off an electric motor, in particular an electric tool, preferably with housing dimensions according to European standards.
  • the invention has for its object a device to create the type mentioned, in which the contact pressure is independent of the switching operation.
  • the contact bridges via one provided on a connection Swivel bearing pivotable, the contact bridges preferably by means of a common contact pressure closing spring in each other opposite pivot bearings are held.
  • the result is an extremely compact and partially poor design the device.
  • the axes of each swivel element in the contour areas on the housing side relocatable, preferably the bearing contour for the contact bridge that closes first and opens later comparatively smaller axis displacement than the bearing contour is designed for the other contact bridge.
  • the tax leg for the first closing and contact bridge that opens later on a contact leg of the Contact bridge attacks in the OFF position and this contact leg after pivoting the gift organ to close the assigned contact pairs for closing by the contact closing spring releases or opens to open.
  • the tax leg for second contact bridge that closes later and opens earlier this attacks via a pin in the OFF position, the Pin after the axis of the first swivel member on another Actuation of the slide as a result of the axis displacement of the second Swivel organ the second contact bridge to close through the Contact closing spring suddenly releases or opens to open.
  • FIGs 1-8 is a device for the input and Switching off an electric motor, in particular an electric tool in the form of a switch 10 with two contact bridges 11 and 12 for two connection contact pairs 13, 14 and 15, 16 shown are housed in an electrically insulated housing 17.
  • a slide switch is designated in the housing is guided and in a manner not shown in the Is biased OFF position shown in Figure 1.
  • the slide switch 18 is inside the housing 17, as is also the case in FIG. 2 remove, massively expanded and possesses on opposite Sides 19 and 20, in which pin 21 is articulated are.
  • the pins 21 are at the ends of arms 22 and 23, respectively formed angled, which to a first pivot member 24 and belong to a second donor member 25.
  • the gift organ 24 has a pivot axis 26 which, as can be seen in FIG. 2, are loosely pivotably mounted in recesses 27 on the housing.
  • the recesses 27 form a bearing contour area that one resembles an enlarged long hole and a side slightly increasing evasion of the bearing axles 26 against the effect a tension spring 28 allows the other end of the Bearing axis 29 of the swivel member 25 is articulated.
  • the swivel organ 25 is in turn with its protruding axes 29 in housing-side bearing contour areas 30 stored loosely.
  • the Areas 30 are approximately twice the size of the storage areas 27 and an equilateral rhombus formed approximately.
  • the contact bridges 11 and 12 are at their upper end Contacts 15 and 13 pivotable by a single contact closing spring 31 held.
  • first pivot member 24 there is also a control leg 32 at a first pivot angle ⁇ with respect to the pin 21 integrally formed, the end of which in the position shown in FIG on a leg 35 of the first contact bridge 12 attacks.
  • second pivot member 25 On the second pivot member 25 is a control leg 33 integrally formed with an abutment pin 34 angled at the end, the contact pin 34 with respect to the pin 21 by one Angle ⁇ is rotated about the axis of the leg 29, and the angle ⁇ is greater than the angle ⁇ .
  • FIGS. 3-6 show different phases of the switch-on shown, in Figure 3, the slide 18 only about 2 mm is pressed and the contact bridge 12 on the Contact 14 is present. This switching on is achieved been that by the slide valve 18, the axes 26 and 29th while pivoting and further tensioning the tension spring 28 after have been shifted outside, the control leg 32 den Leg 35 of the switching contact bridge 12 has released.
  • the pivot axes 26 and 29 are pushed further outwards, then the pin 21 the dead center between the two Swivel axes 26 and 29 with the result that the Swivel axis 29 jumps up according to Figure 5 and then the Pin 34 the second contact bridge 11 for closing contacts releases.
  • the device adopts the ON position shown in FIG. 6, in which the pins 21 have reached the lowest position and accordingly the pivot axis 29 due to the effect of Tension spring 28 has shifted inwards.
