Definitions

  • the invention relates to a switch with a housing, with a mass in the housing along a path between a Rest position and a stop is movable with a first Reset element, which is the mass relative to the housing in the Prestressed rest position, with one of the crowd moving entrained actuator that in a switching position actuated a switch contact, and with a second reset element, which is designed as a spring and the mass with the Actuator connects, the actuator the Switch contact closes before the mass against the stop running.
  • a switch of the type mentioned above is from WO 93/06613 known.
  • switches There are two general requirements for switches, the one concerns the closing force and the other the minimum closing time.
  • the closing force is required to be is independent of the actuation force, therefore independent of the magnitude of the force used to operate the switch this closes securely.
  • override / snap mechanisms are provided in which e.g. a Snap spring when a minimum actuation force is exceeded snapped from their rest position into their switching position and doing it for a defined time with a defined force Switch contact actuated. This minimum operator will often specified by a switch spring.
  • the mass rather switches the switch contact itself.
  • the switching process is here over the Weight and / or the inertia of the mass triggered, so that the Mass itself has to perform several tasks.
  • WO 93/06613 is a switch for Detect an accident of a vehicle known.
  • the known Switch is a piston-like mass in one Housing stored, the mass by means of a relatively soft Spring is held in a rest position. Running in bulk an actuator that is relative to the mass by means of another Spring is supported. In the event of a vehicle impact the mass moves from its rest position and becomes pneumatically braked by the front of the piston-like mass air cushion located in the housing is compressed. To Passing through a predetermined distance includes Actuator located contact an electrical switch. The actuating part also provides a central opening free in the piston-like mass through which this occurs relax air cushions, i.e. the air can flow off. In this known switch, therefore Movable mass is braked exclusively by pneumatic means.
  • this task solved according to the invention in that the first return element is designed only as a spring, and that the second Return element forming spring stiffer than that of the first return element forming spring is designed.
  • the object underlying the invention is based on this Way completely solved.
  • About the choice of mass and properties of the reset element are independent of each other the required switching forces and switching times are set, the security of the switching is given by the fact that not the mass itself, but rather an independent one Actuator performs the switching function.
  • With the new switch can now be used relatively simple masses have different dimensions and weights depending on the requirements can. However, for each variant of the new switch always use the same actuator, so that the total storage and production costs are significantly reduced.
  • the new switch can be used as a position sensor, tilt sensor, inertia sensor, Accelerometer or as a safety switch e.g. be used in robotics. It is in robotics namely known, hoses filled with compressed air in the area to be attached to areas of a robot at risk of collision, so that a pressure wave is triggered upon contact with these hoses which is recognized by a safety switch which then turns off the robot. With the new switch it is now possible to accelerate the mass over this pressure wave.
  • Minimum force or minimum acceleration determines the required is so that the actuating part is in contact with the switch contact arrives. Because the second reset element is designed stiffer it is not yet deflected during this switching phase. After switching, the movement continues Mass now against the force of the second restoring element, which determines the minimum closing time.
  • the actuating part is electrical is conductive and the switching contact from two spaced There are contact surfaces with which the actuating part at in Switching position mass is in the system, so that it connects them electrically.
  • the sole figure shows one in principle Longitudinal section through the new switch.
  • 10 is the new switch, which is here serves a battery 11 optionally with a consumer 12th connect to.
  • the switch 10 has a housing 14 in which a longitudinally displaceable mounted actuator 15 is arranged, the rotationally symmetrical and to the right in Fig. 1 is movable.
  • the actuator 15 is inside as Guide tube 16 formed for a mass 17, which in Fig. 1st also mounted longitudinally and movable to the right is.
  • a first restoring element 18 is provided in the form of a tension spring 19, which the actuating part 15 in Fig. 1 to the left a shoulder 20 pulls.
  • a further restoring element 21 is located in the guide tube 16 arranged, which is formed here by two tension springs 22.
  • the tension springs 22 are between the actuating part 15 and the Mass 17 is provided so that it follows the mass 17 in Fig. 1 preload against stops 20 'on the left.
  • the construction is chosen so that the restoring element 21 is stiffer than the first restoring element 18th
  • FIG. 1 it is possible to do this only schematically in FIG. 1 indicated operating part 15 directly on the tension spring 19 form and the mass 17 directly in the housing 14 respectively. It is only important that the switching contact 27 of the actuating part 15 and not closed by the mass 17 which only serves to trigger the switching force to implement in a movement of the actuating part 15.
  • By the further reset element 21 and the opposite Switching path 31 enlarged path 32 of mass 17 is additional easily determines the minimum closing time that reaches without the new switch 10 being triggered by impulses, elastic bounce etc. can bounce.
