Embodiment Construction

[0013] The torch 1 basically comprises: a housing 2 with a torch head 3; a battery pack 4 with a pressure switch 5 arranged on the end side; an end cap 6 with a button 7. The button 7 has a head part 8 , a guide 9 and an operating part 10 . In order to prevent the button 7 in the assembled state from falling out of the end cover 6, a ring-shaped stop surface 11 is designed on the guide 9, which has the same shape as the one inside the end cover 6. The annular stop surfaces 12 abut against each other. In order to protect the interior of housing 2 against the penetration of water, a sealing element 13 is arranged between button 7 and pressure switch 5 . The sealing element is preferably designed to be rotationally symmetrical and has an annular clamping surface 14 and a projection 15 in which a recess 16 in the form of a blind hole is formed. The operating element 10 engages in this groove 16 . Corresponding threaded sections 17, 17' are provided for connecting the battery h...

Description

technical field [0001] The invention relates to a waterproof flashlight comprising: a housing; a battery sleeve mounted in the housing, the battery housing having a pressure switch on the end side; and an end cap having a button which is in operative connection with the pressure switch. Background technique [0002] Flashlights of the type mentioned at the outset are known from the background art. For example, such a flashlight has been introduced in DE101007032003, but its shortcoming is not waterproof design. [0003] A waterproof flashlight is disclosed in DE2413016, which has a pressure switch arranged in the housing. The pressure switch has a switch cover made of rubber, an additional sealing ring is arranged between the switch cover and the housing. In order to actuate the pressure switch, it is only necessary to press the elastic switch cover downwards. [0004] Waterproof flashlights are often used outdoors, where the demands on the robust construction of the flas...
