Definitions

  • the invention relates to a device with at least one sensor switch for electrical Devices and machines according to the preamble of claim 1, wherein the At least one sensor switch is assigned an operating zone when it is touched the associated sensor switch is activated by an operator.
  • the sensor switches include not only capacitive and inductive sensor switches, but also on light beams or on the interruption light sensor switches reacting to light beams. These sensor switches can be non-contact Proximity switch to activate a finger one operator is sufficient for the operating zone, or touch switch be activated by touching the operating zone.
  • Electrical Devices and machines with which the invention can be used are in particular Electric cookers, but also electric dishwashers, electric washing machines, electric tumble dryers, sound reproducers and picture reproducers, Radio and television sets, elevator cabins and control panels on or next to Elevator shaft doors, etc.
  • a non-contact sensor switch that reacts to the interruption of a light beam is known from DE 40 07 971 A1.
  • a capacitive sensor switch is off EP 0 054 306 A1 (81 110 493.4). With capacitive sensor switches by moving an operator's finger to an operating zone or touching this operating zone changes a capacitance value of the sensor switch. Similarly, the inductance value of inductive sensor switches is changed.
  • a special feature of the sensor switch is that there is no actuation pressure to actuate it is required.
  • a control panel is known from DE 28 42 622 C2, which is covered with a rigid plastic film, so that microswitches built into the control panel and spaces between these microswitches and a cover plate the control panel can not pick up any dirt, so that the control panel is easy to sterilize and also used in operating rooms of hospitals can be. So that the control elements of the microswitch through the plastic film
  • the plastic film in the area of the control elements of the microswitches can be operated in the form of a bubble, convexly curved outwards.
  • the bubbles of the plastic film are flexible. When the bubbles are pressed in, a tangible and audible "pop frog effect". When the blister reaches its "sticking point" reached, their spring resistance suddenly drops. By pushing the bladder in further contrary to their reduced spring resistance, the control element of the microswitch pressed until it stops.
  • the object of the invention is to achieve devices which at least a non-contact sensor switch or a touch sensor switch included, such that the functional reliability when operating the sensor switch is increased.
  • the construction should be simple and increase the functional safety, no electricity-consuming electrical elements are required be.
  • the device with at least one sensor switch for electrical devices and machines is characterized according to the invention in that the operating zone Has a crack frog effect, which is arcuate such that it by an operating pressure of the operator against the operating zone Arc shape is bent through a sticking point, at which it audibly clicks and their spring force suddenly decreases, but when the actuating force is removed due to their spring force through the sticking point back to their original shape snaps back.
  • the operating zone Has a crack frog effect, which is arcuate such that it by an operating pressure of the operator against the operating zone Arc shape is bent through a sticking point, at which it audibly clicks and their spring force suddenly decreases, but when the actuating force is removed due to their spring force through the sticking point back to their original shape snaps back.
  • the operating zone of the Sensor switch by a convex surface of the crack effect spring or an element extending over the click effect spring.
  • This convex, bubble-like or dome-like increase in the operating zone enables an operator also blindly the correct position for operating the sensor switch to find. This will ensure the reliability of correct operation of the Sensor switch significantly increased. In all cases, the advantages of the sensor switch remain receive. To achieve the effect according to the invention is neither an expensive one Construction still requires electricity-consuming lighting.
  • the device according to the invention shown in Figure 1 contains several sensor switches 2, of which only one is shown.
  • the sensor switches 2 are located under a carrier plate 4, which in the example shown has a cover plate 6 is made of stainless steel and rests on the trough 8 of an electric cooker.
  • On A front section of the carrier plate 4 is a control panel with a Main plate 10 made of resiliently flexible material, in particular plastic or Metal.
  • the main plate 10 is glued to the carrier plate 4 by an adhesive layer 12 and has in the operating zone 14 of each sensor switch 2 a convex to the outside curved elevation in the form of a bubble or dome, the surface of which is the operating zone 14 defined to activate the sensor switch.
  • the convex elevation towards the outside 16 is formed by a material deformation of the main plate 10 and can by the deformation process has a thinner thickness than the areas of the main plate 10 outside the elevation 16.
  • the elevations are for easier understanding 16 hereinafter referred to as "calottes"
  • the domes 16 consist of resilient material and are arcuate in this way trained that they form a pop frog effect spring, which by an actuating pressure an operator on their curved outer surface 14, which the Operating zone defined, bent against a curve point by a sticking point in which it audibly cracks and its spring force suddenly decreases.
  • the calotte or spring 16 jumps through its own Spring tension back to its original shape through the sticking point, which is shown in Figure 1.
  • the sensor switch 2 can on light beams, on changes in capacitance or on changes in inductance responding sensor switches.
  • Figure 1 are an example Capacitance areas 18 of the sensor switch 2 shown, their electrical capacity is changed when an operator moves a finger to the operating zone 14 approaches and the dome 16 bends against its arc shape.
  • the Distance between the operating zone 14 and the sensor switch 2, i.e. the calotte 16 and the underlying area of the carrier plate 4 be translucent.
  • the carrier plate 4 and the main plate 10 must also be translucent at least in partial areas if the surface of the main plate 10 is to be illuminated from its underside, for example by an in 1 schematically indicated electrical light 20.
