Abstract
The present invention relates to a flashlight with a flashlight casing and a push switch, latching switch or rotary switch contained in an end cap having a switch housing in which a first and a second contact engage. According to the invention, the first contact is a leaf spring engaging in direct electrical connection directly against the electrically conductive flashlight casing or directly against the electrically conductive end cap that is also detachably connected to the flashlight casing, the second contact being a bent leaf spring outside the switch housing directly connected to a power supply.
Claims20
A flashlight with a flashlight casing and a push switch, latching switch or rotary switch contained in an end cap having a switch housing in which first and second contacts can engage, wherein the first contact is a leaf spring in electrically conductive contact directly against the electrically conductive flashlight casing or directly against the electrically conductive end cap that is detachably connected to the flashlight casing, wherein the second contact is a bent leaf spring outside the switch housing and is directly connected to a power supply.
A flashlight comprising:
- a hollow electrically conductive casing extending along an axis and having a front end and a rear end;
- at least one battery in the casing having a pair of poles;
- a light source at the front end of the housing connected electrically between one of the poles of the battery and the casing;
- an end cap releasably secured to the rear end of the to casing;
- a first elastically flexible leaf-spring strip contact having an inner end inside the end cap and an outer end projecting therefrom;
- a first formation on the end cap pressing the outer end of the first contact axially rearwardly against an axially forwardly directed face of the casing;
- a second elastically flexible leaf spring strip contact having an inner end inside the end cap and an outer end projecting from the end cap;
- a second formation on the end cap positioning the outer end of the second contact in direct engagement with the other pole of the battery;
- and
- an actuating element carried on the rear end shiftable from outside the casing and outside the end cap between an actuated position electrically interconnecting the inner ends of the contacts and an unactuated position with the inner ends of the contacts out of electrical connection with each other.
