Definitions

  • This invention relates to an electric switching device for two circuits mounted in the handle of a consuming apparatus, both of which circuits are successively switched on, or only one of them 5 is switched on, whilst both are switched off simultaneously.
  • the switching device consists of two toggle switches inserted in the two circuits and mounted in the handle one behind the other in the longitudinal direction of the handle, two press buttons movable against one another and acting directly on the toggle switches being arranged between the latter, transversely to the handle, one of the press buttons being adapted to switch on only one toggle switch or both toggle switches one after the other, whilst the other is adapted to switch oil the two toggle switches simultaneously, a spring being mounted between the two press buttons which returns the latter automatically into their initial position.
  • the consuming apparatus which especially come into question are hot air douches which are desired to operate not only with hot air but also with cold air instead.
  • the first case only the one toggle switch is switched on which lies in the motor circuit.
  • the second case by the additional switching on of the second toggle switch, also the toggle switch lying in the heating circuit is switched on.
  • the hot air current is prevented from being inadvertently switched on and thereby the heating resistance prevented from being overheated.
  • the simultaneous switching off of both circuits has the same efiect and such switching action is quick and positive.
  • the successive switching on of the circuits may be eflected in various ways.
  • the invention provides a very simple and compact construction of switching device which can be mounted in a handle of the usual dimensions of a consuming apparatus.
  • the switching on and oil" of the circuits can be efiected conveniently by usin'gone hand only, viz., the one holding the apparatus, the other. hand being free for other manipulations.
  • the construction according to the invention is such that the two toggle switches can be easily and conveniently mounted and secured in position in the handle of the consuming apparatus.
  • the accompanying drawing illustrates, by way of example, a handle for a hot air douche provided with an improved switching arrangement.
  • Figure 1 shows a longitudinal section of the (Cl. 200157) I improved device with the press buttons and toggle switches in the starting position;
  • Figure 2 is a plan view showing the circuit closing position of the upper toggle switch (cold air) operation
  • Figure 3 illustrates a modification oi the improved device.
  • the handle which is preferably made of a compressed electric insulating fibrous material, is divided longitudinally 10 into two halves a, b and is made hollow.
  • the two halves are held together, partly by a tubular clamp z, which connects the inner end of the handle to the actual apparatus, and partly by a screw 0.
  • Two oppositely moving press but- 15 tons d and e are arranged transversely to the handle,one of them serving as a switching-on button and the other one as a switching-off button.
  • the two press buttons are kept apart by a spring f inserted between them, being caused 20 to abut against the inner wall of the two halves of the handle.
  • the switching-off button c has a smooth inner surface 9', whilst the switching-on button d is provided with a stepped inner surface having two switching steps h and i, the latter 25 lying further behind the outer end of the press button ascompared with the former.
  • Two toggle switches are arranged laterally with respect to the two press buttons, one behind the other in the'longitudinal direction inside a hollow space 30 providedin the handle.
  • the toggle switch adjacent to the small switching step h of the switching-in button serves for the connecting up of the motor circuit, and the switch adjacent to the larger step i of the switching-on button serves 35 for the switching-on of the heating current, the two steps hand i of the switching-on button being made of diiferent heights.
  • Each switch has a support which consists of 45 two upright parts n (in Figure 1 they lie one behind the other) and two strongly acting foot plates 0', 0. The latter are inserted (by friction or clamping) in corresponding slots provided in v the two handle halvesin the half I) so as to be 50 firmly seated, and in the other half so as to be lightly seatedwhereby the two switches can be secured in the handle in a very simple way.
  • the two-arm lever q, r is mounted in pivot holes p of the two uprights n, the end of the arm q 66 the rouge of operation of the h or i of the switching-oh button.
  • a rod .9 is on to the cud oi?
  • the switching-oif huttou e When it is desired to stop the operation of the sppcratus the switching-oif huttou e is pressed down end its inner smooth surface g, whilst compressing the spring acts simultaneously on the ends of the arms q of Tooth switches, thereby switching-oil simultcneously the two circuits, whereupon it is returned automatically to its original position by the spring 1
  • the switching-on hutton is pressed down, only to such on extent until the upper switch is operated, which, apart from the noise of the pact or the switching stirrup, is also perceived loy the hood, owing to the chsnged resistance of the press button.
  • the handle being divided longitudinally into two halves in which the two press buttons are respectively mounted opposite one another, and each one of the said handle halves having two transverse slits on opposite sides of the press button mounted therein, and the two transverse supporting plates lying firmly in the transverse slits formed in the one half and lightly in the trans-' verse slits formed in the other half of the handle.
