Les Jones - it would be operating between 4-5 hours at a time, those parts ideas are great only I wouldn't know how to build it. . . .and I don't have access to soldering or and tools to get the job done. so really it kind of has to be simply put together. . . .not sure if that helps or not
Tony Stewart - "if he told us what is being switched" thats over thinking it, this is way simpler than that
alec_t - I was hoping for something small, that could fit in your hand or slightly larger. that can rotate slowly and with force. enough force to press a button. Im at home right now and will add pictures as soon as I'm able to better describe my dilemma. I find it really simple but laughable that I can't find a small rotating device with force. . .
thanks for the responses everyone, once I post pictures of what I'm trying to do as well as a motivation for why I'm trying to do it will hopefully answer some questions. Les_Jones had suggested parts that I trust would get the job done, however I wouldn't know how to build it lol
another idea I had was to find a DC motor, easily power-able and spins! but those motors spin way to fast and when slowed down lose their torque.
had to google this:
Slider-crank mechanism, arrangement of mechanical parts designed to convert straight-line motion to rotary motion, as in a reciprocating piston engine, or to convert rotary motion to straight-line motion, as in a reciprocating piston pump.
