Definitions
- the invention relates to an electrical push button switch, for example off, series, Changeover, serial change or cross switch, or push button, with at least a probe element with a translucent design that can be placed on the front Touch cap for actuating at least one contact point, with a base and with one with the base lockable upper part, which upper part is perpendicular to the mounting surface
- Directional guide for the probe element slidably locked to the upper part has, wherein two lamps are provided which can be operated independently of one another are and lamp holders are provided for the first and for the second lamp.
- Such an electrical key switch is known from EP-A-006 08 204.
- the first lamp is used to illuminate a function of the key switch Characters.
- the second lamp serves as a control lamp for displaying the activated ones Function. Both lamps have corresponding sockets on a circuit board assembled.
- a switch or key switch proposed in DE 44 08 366 A1 has one Centrally arranged lighting unit, which with a translucent trained Backlit probe element provided and in this way a very striking orientation lighting.
- the invention has for its object a switching device of the type mentioned with simplified configuration of the two lamp holders for the first and second lamp specify.
- the second lamp is preferably arranged in the probe cap and as a control light provided, which is always switched on, even if that of the concerned Switch operated circuit is turned on. This is for every user already recognizable from a distance in which switch position the switch in question is currently located.
- the second one as a control light Lamp arranged eccentrically according to an advantageous embodiment of the invention.
- the second lamp can be above it also be contrasted in color to the first lamp, so that optional by different coloring of the light signal and / or by different Positioning of the light signal is visible to the outside, in which Switch position the switch in question is currently.
- the translucent trained Key cap or the switchgear cover on the back that is to say Lamps facing a shield against the first lamp, so that on the surface on which the control light is displayed does not appear simultaneously a glow from the orientation light to false indications or misunderstandings leads with regard to the respective advertisement.
- the lamp holder has a recess in the holder for the first lamp for the second lamp, a housing formed from two shells, in which the second lamp is inserted.
- This provides an advantageous embodiment of the invention before that the second lamp is designed as a glow lamp and together with a resistor is inserted in the housing of the associated lamp holder.
- the housing is opened for loading by swiveling the trays open be and the glow lamp together with the resistance to the intended receptacle inserted in the housing of the second lamp holder become.
- connection or switching contacts of the respective Contact point have so-called contact guides, in which the terminal contacts designed as busbars second lamp holder guided and non-positive, for example are acted upon by appropriate contact springs. hereby will be a safe positioning of the second lamp respectively of the second lamp holder and thus a reliable contact reached.
- first lamp 20 serves to backlight the key cap and not shown here thus as an orientation light to keep the electrical even in the dark Find switch 10.
- a lamp holder is on the connecting contacts 18 on one side 22 placed, the details of which are shown in FIG. 2 are.
- This lamp holder 22 is T-shaped in plan view and has one at the distal end of its web 24 Recess 26, which is for receiving the one in FIG. 2 above serve drawn first lamp 20.
- the recess 26 is approximately square and also has two opposite Side contact tabs 27, which with corresponding contact tabs 21 work together on the first lamp 20 and the first Supply lamp 20 with electricity in this way.
- receiving pockets 28 are arranged, which for receiving a second lamp 30 with Power supplying second lamp holder 32 are used in the 3 and 4 is shown in more detail.
- the second lamp holder 32 has one of two shells 33, 35 formed housing 34, which shells 33, 35 by a hinge 36 are captively connected. This is preferably Joint formed as a film hinge.
- the housing 34 the is called in the lower shell part 33 facing the switch the second lamp 30 is inserted with a resistor 31, which via helical contact springs 37 with corresponding, here Contact surfaces not shown in the receptacles 28 on the first Work lamp holder 22 together.
- cylindrical pin 38 which in the form Intervene recordings 28 on the first lamp holder 22 and so the second lamp holder 32 together with the second lamp holder arranged therein Fix lamp 30.
- the one which is pivotally formed on the first shell 33 as the upper housing part second shell 35 of housing 34 has a window 39 through which the light emitted by the second lamp 30 can exit from the front and thus the desired switch position indicator of switch 10 signals.
- locking elements 40 is the upper shell 35 with the lower shell 33 positively connectable.
- both the first lamp 20 and the second lamp 30 serve as a rail on the first lamp holder 22 molded contacts 23 which are axially parallel to the direction of extension the contact springs 37 of the second lamp holder are directed downwards and when inserting the first lamp holder in the upper part 16 of the switch 10 automatically there Contact existing contacts 18.
- the individual are dependent on the respective switching position Contacts 18 live or de-energized, so that the concerned Terminal contacts 23 on the first lamp holder 22 live or are de-energized.
