Thy larryd for your reply,
I have links to all of my components, but only in German is that a problem ? I want to toggle a 5V Water Pump powered by USB with an Smarthone charger (min 1A) the Water pump needs 2,5-6 V and works at 130-220mA.
I hav no schematic of my wiring. If you say you need it for an explicit answer, I can make one.
