can somebody help me ?
it has to be very small and work on a single 18650

You may have to do some searching in some electronics catalogs, but a nice little "latching relay" is what you need.

That will allow you to press once to turn on and press again to turn off.

Mouser or Allied Electric come to mind quickly, but others my chime in unless you have a local source to go to.

it seems that for using a latching relay i have to inverse polarity at each impuls of the switch so this will not work for me

 

[landries]

can i use a led driver to power a small relay?
i think there are led drivers that works whit a momentary switch,but i do not know wich one
please help me
greetings

All I can suggest is to replace the momentary switch with a push on/push off switch of the same size.

i can not change the switch as it is a magnetic sliding switch
