Abstract
A torch (flashlight) and a method for producing a torch housing and a torch head provides a torch which is of simple design and is robust. The torch has a rotary switch, in which torch clear classification of the selected function is possible, so that regular function monitoring can be dispensed with. The torch housing and the torch head can be connected in a captive manner and so as to be rotated in relation to one another to form a rotary switch having different switching states. Markings are arranged on the housing and on the lamp head. The markings allowing clear classification of the switching states. After the torch is first assembled and after the torch is first switched on, to clearly define the switching states by in each case a torch-head-side and a housing-side marking for subsequent switch-on processes.

A flashlight comprising:
- a flashlight housing;
- a flashlight head connected to the flashlight housing in a captive manner and such the flashlight head can be rotated in relation to the flashlight housing to form a rotary switch having different switching states;
- a plurality of markings arranged on the housing and on the lamp head, the markings allowing unambiguous classification of the switching states;
- a plate and an annular ring-shaped contact spring rotatably mounted between the flashlight head and the flashlight housing, wherein the annular contact spring is movable relative to the plate, the contact spring making contact with a housing-side, annular, electrical contact area by way of a first partial section and there latching into predetermined positions and passing over electrical contact zones of the plate by way of a second partial section, the annular ring-shaped contact spring having a single annular course.
A method for producing a flashlight comprising:
- providing a flashlight housing and a flashlight head which can be connected to one another such that they can be rotated and in a captive manner in order to form a rotary switch having different and selectable switching states;
- providing unambiguous classification of the switching states, after the flashlight is first assembled and after said flashlight is first switched on, to clearly define the switching states by in each case a flashlight-head-side and a housing-side marking for subsequent switch-on processes;
- providing a plate and an annular ring-shaped contact spring rotatably mounted between the flashlight head and the flashlight housing, wherein the ring-shaped annular contact spring is movable relative to the plate, the contact spring making contact with a housing-side, annular, electrical contact area via a first partial section and the contact spring latching into predetermined positions and passing over electrical contact zones of the plate by way of a second partial section, the annular ring-shaped contact spring extending along a single annular course.
