Definitions

  • the invention is based on a tilt switch according to the preamble of claim 1.
  • Such an inclination switch which operates essentially reliably, but in which the distribution of the contact forces exerted by the ball over the two contact points is not adequately taken into account for the inclination angle at which the inclination switch makes contact.
  • the invention has for its object to develop a tilt switch according to the preamble of claim 1 such that the contact is improved in the inclination range in which the contact is made, and that the contact force distribution in this area should be as even as possible at the two contact points.
  • 10 denotes an inclination switch with a housing-shaped first contact element 11 made of an electrically conductive material.
  • the first contact element contains a first conical depression 12 with a cone angle ⁇ , which merges into a second conical depression 13 with a smaller cone angle ⁇ .
  • a ball 14 made of electrically conductive material rests in the second conical depression 13 in the rest position of the tilt switch 10.
  • the first contact element 11 has a first electrical connection 20 and the second contact element 17 has a second electrical connection 21.
  • the operation of the tilt switch 10 according to FIGS. 1 to 3 is as follows.
  • the cone angle ⁇ of the first conical depression 12 is ⁇ + 2 ⁇ , the angle ⁇ determining the distribution of the contact forces between the two contact points X, Y (FIG. 3).
  • a tilt switch 30 according to FIG. 4 has a similar structure to the tilt switch 10.
  • the tilt switch 30 has a first housing-shaped contact part 31 which contains a rotationally symmetrical depression 32 in the form of a curve. Starting with an opening angle ⁇ 'at the bottom end 33 of the recess 32, the opening angle of the recess increases upwards, so that there is an effect similar to that of the recesses 12 and 13 according to FIG. 1.
  • tilt switch is a so-called dead man's switch for radio devices to be held in the hand or worn on the body.
