Definitions

  • the present invention relates to a circuit arrangement within a flashlight with a switch, a housing, an actuating element and a first and a second contact element, both of which engage in the housing.
  • circuits are commonly used in flashlights, but they can also be used in other switches, such as in lamps or other electrical equipment.
  • the circuit arrangement is often integrated in the end cap, which is screwed onto the flashlight housing, wherein the battery or the accumulators are introduced with unscrewed end cap in the flashlight housing.
  • the second contact element is connected to a coil spring, on the one hand fixes the batteries within the flashlight and on the other hand connected to a pole of the battery, so that the current flows through the coil spring.
  • the first contact is usually passed over the end cap, so that the electric current continues to flow from there via the thread or other contact surfaces via the flashlight housing to the consumer.
  • the circuit arrangement according to claim 1 wherein according to the invention, the first contact element is directly or indirectly electrically connected to a light source and the second contact element outside the housing is formed as a bent leaf spring and is directly connected to a power supply.
  • the first contact element is directly or indirectly electrically connected to a light source and the second contact element outside the housing is formed as a bent leaf spring and is directly connected to a power supply.
  • a large number of contact surfaces is avoided.
  • a contact between the first contact element and the contact spring is saved.
  • the current is no longer guided by the coil spring, so that no power is lost due to the relatively high self-inductance of a coil spring.
  • less power is lost by the circuit arrangement according to the invention, so that it is available to the light source.
  • the light source is an LED and a battery or an accumulator is provided as the current source.
  • the use of an LED as a light source reduces power consumption, so that more energy is available to generate light.
  • the first contact element is a bent leaf spring, which is directly connected to the electrically conductive flashlight housing.
  • the light source is only indirectly connected to the first contact via the conductive housing of the flashlight, the circuit arrangement is nevertheless reduced by at least one contact, because usually the first contact is guided via the end cap, so that the thread between the end cap and the housing is used as a contact surface.
  • An advantage of this embodiment is also that the first contact is always pressed evenly against the housing. Thus, regardless of the position of the end cap, in which the switch is arranged, a secure contact is created.
  • the first contact may also be directly connected to the light source, with the end cap and the housing are then not separable from each other and are always held together at least over the first contact element.
  • the actuating element is axially movable, and on the front side has an electrically conductive contact plate, which is connectable to both contact elements simultaneously.
  • a contact element may be formed within the housing as a bent leaf spring, which is spaced in the relaxed state of the other contact element, wherein both contact elements are connected by the actuating element against the force of the leaf spring.
  • the actuating element is a pressure or rotary knob which is axially movable against the force of a spiral spring. As a result, the actuating element is kept at a distance from the contacts in the relaxed state, so that unintentional switching on or off of the flashlight is prevented.
  • locking elements are provided on the confirmation element according to a further advantageous embodiment of the invention, so that a tactile function or optionally a permanent switching function is adjustable. This not only increases the handling of the flashlight, but also the functionality.
  • the switch 1, as it is preferably used in the circuit arrangement according to the invention, has a housing 2 and an actuating element 3. Further, a first contact element 4 and a second contact element 5 is provided, wherein both contact elements 4, 5 formed as a curved leaf springs for a secure contact are (cf. Fig. 1 a) , Such a switch is integrated with the protruding from the housing 2 contact elements 4, 5 in a pressure switch 6 (see. Fig. 1 b) , which can be screwed on the end of a flashlight housing 7 (see. Fig. 1 c) , Within the flashlight housing 7 is a battery 8 with the poles 9, 10, wherein the pole 10 is connected to the second contact element 5.
  • the first contact element 4, however, is in communication with the flashlight housing 7.
  • the circuit arrangement is thus formed by the battery 8, the switch 2 with the contact elements 4, 5, the flashlight housing 7 and the light source 11.
  • the switch 2 In the event that only one contact is present within the switch, are in circuit arrangement according to Fig. 1c only five contact surfaces 12 1,2,3,4,5 formed.
  • a switch As it is preferably used in the circuit arrangement according to the invention, show the Fig. 2a , b.
  • the actuator 3 is mounted axially movable, being held by the contact elements 4, 5 by the force of the coil spring 21 at a distance.
  • the actuating element 3 according to Fig. 2a has frontally a contact plate 22 which is pressed upon actuation of the actuating element 3 on the contact elements 4, 5, wherein the circuit is closed.
  • the second contact element 5 is formed within the housing 2 as a leaf spring, wherein the contact elements 4 and 5 can be brought into contact by means of the actuating element 3.
  • the second contact element 5 is formed within the housing as a leaf spring is in the Fig. 3a and b the actuation process shown schematically.
