Definitions

  • the invention relates to an electrical switch according to the preamble of patent claim 1.
  • Such electrical switches are used for switching on and / or off of electrical devices by a manual pressure operation of a user.
  • these pressure switches are used for example in the home appliance industry for household appliances, such as coffee machines, vacuum cleaners o. The like., For devices in the entertainment industry, etc ..
  • Such an electrical switch may have a housing.
  • the housing contains a contact system. From the housing protrudes a movable actuator for switching the contact system between two switching positions, namely an off-switching position and an on-switching position, out.
  • the actuating member is in operative connection with a guide cam in the manner of a switching heart into which a latching means designed as a pin can be engaged, so that the actuating member can be locked in at least one of the switching positions by the interaction of latching means and guide cam.
  • the actuator is locked or locked in the on-switching position, whereby the switch remains in the on-switching position after switching.
  • this switch can be switched off only by renewed manual actuation of the actuator.
  • Such a switch is also from the US 2001/0014027 A1 known.
  • a force acting on the contact system moving means is provided in this switch, so that the contact system is nonmanually switchable from one lockable switching position to the other switching position.
  • the invention has for its object to develop a further switch which is non-manually switchable from the lockable switching position to the other switching position.
  • a pressure switch should be unlocked both mechanically, ie manually by the user, as well as electrically / electronically, ie without manual intervention.
  • optionally in a variant of the pressure switch should only turn on mechanically and can be switched off electrically / electronically.
  • the locking means by means of the movement means in and / or out of engagement with the guide cam is movable.
  • the actuator located in the locked switching position is unlocked.
  • the switch "electrical / electronic" at least switched off.
  • the switch may expediently have a housing.
  • the contact system is located in the housing.
  • the actuator protrudes from the housing.
  • Electrical connections for supplying the electrical voltage for the switch protrude from the housing.
  • the moving means is arranged in the housing.
  • the movement means may consist of a controllable actuator, such that the latching means is moved when the actuator is actuated.
  • the actuator is a solenoid having a coil.
  • the locking means can in a simple way from a pin exist, wherein the pin can be articulated on the armature located in the coil of the electromagnet.
  • the guide cam is arranged movable in the transverse direction to the actuating direction and fixed in the direction of actuation of the actuating member on the actuator.
  • the pin of wire in the manner of an L-shaped bracket can be designed in a cost effective manner.
  • a programmable electronics which in particular comprises a timer for the controlled unlocking of the actuator from the lockable switching position.
  • the electronics are arranged on a circuit board located in the housing. For example, then in standby, the timer can be set in motion to turn off a coffee after a certain time.
  • the switch can have an additional auxiliary contact.
  • the auxiliary contact detects the locked switching position of the actuating member.
  • the guide curve can be configured such that only a mechanical / manual switching into the lockable switching position, but no mechanical / manual switching is made possible in the other switching position by means of the actuator. The electrical / electronic unlocking of the switch from the lockable switching position is then optionally initiated via a further auxiliary contact.
  • the guide curve is designed such that only after two or more manual actuation of the actuating member is a mechanical switching from the lockable switching position allows.
  • a second detent position may be provided in the switching heart, so that the switch is also located in the on-switching state in the second detent position. Only from the second detent position then a manual switching off the switch is possible. Such a design thus enables the switching off of the electrical appliance even if the automatic shutdown fails.
  • the switch has a resistor in the manner of a shunt for current measurement.
  • the resistance can be integrated in a meandering manner in a connection of the switch.
  • the current measurement can be used, for example, to detect the standby mode for the electrical appliance. So it can then be detected in a particular flowing stream that, for example, the coffee machine is in operation. In this case, the coffee machine is not turned off because it is not yet in standby.
  • the switch can be provided with a lighting.
  • a light source such as a light emitting diode, an incandescent lamp, a glow lamp o. The like., Be located in the housing of the switch.
  • the light source is arranged on the circuit board in the housing.
  • the pressure switch which optionally has additional lighting, is provided with a built-in, movable switching heart for mechanical switching on and / or off.
  • the switching heart is movable in the transverse direction to the actuating direction, but firmly arranged in the direction of actuation.
  • a wire in the form of an L-shaped bracket engages the switching heart for locking.
  • the switch has an integrated coil for electrical / electronic unlocking or switching off the switch.
  • the wire is hinged to the armature of the coil, so that it can be pulled out of the switching heart.
  • the pressure switch is in a variant with an integrated circuit board and a programmable electronics for controlled unlocking, so provided for switching off the switch. If the electrical appliance, for example a coffee machine, goes into standby mode, a timer in the electronics is set in motion to switch off the coffee machine after a certain time. In this variant with programmable electronics integrated in the switch, the duration until unlocking or switching off of the switch is thus determined via a program. Optionally, the load state of the switch can be detected.
  • the pressure switch is provided in a further variant with an additional auxiliary contact which detects the operation of the pusher.
  • the mechanical auxiliary contact is activated when pressing the trigger.
  • the pressure switch has a movable switching heart for mechanically switching on the switch. A mechanical switching off is not with this appropriately shaped switching heart possible.
  • An electrical switch-off of the switch is then initiated via an auxiliary contact.
  • only the auxiliary contact is closed by a single press of the pusher in the ON-switching state. As a result, the elimination of the switch is caused electrically / electronically.
  • the pressure switch is provided with a switching heart shaped in such a way that switching off the switch is enabled only after two or more mechanical actuations.
  • the switching heart for this purpose has a second detent position, wherein the ON-switching state is maintained even in the second detent position. Only from the second detent position is a manual switch off possible. If the automatic switch-off of the switch fails, the option of manual switch-off remains. In this variant, the switch is thus switched off mechanically by pressing the pusher again.
  • the advantages achieved by the invention are, in particular, that a compact small design and a simple construction of the switch by the integrated coil and / or by the integrated coil with electronics is possible.
  • the small design further contributes to the integrated coil with solenoid and jumper wire as a locking means, the jumper wire engages in a laterally displaceably mounted in the pusher switching heart and can be unlocked mechanically and / or electrically.
  • By interchangeability of the switching heart different variants of the switch are possible in a simple manner.
  • Various connection options also allow easy adjustment of the switch for various installation variants in the electrical appliance.
  • a delayed shutdown of the device By detecting the operation of the pusher, a delayed shutdown of the device can be realized. This, for example, brings advantages in coffee machines, where a cleaning cycle can be initiated before the device is disconnected from the mains. This is also advantageous in consumer electronic devices that are galvanically separated from the network only after completion of a specific action. The electronic shutdown can optionally be overridden by pressing the trigger several times. It is also possible in a simple manner different input and / or Ausschaltuxfor the switch.
  • Another advantage is a significant increase in comfort, as can be optimally set by detecting the load conditions of the shutdown. At the same time, the standby consumption for the electrical appliance is reduced, which saves energy.
