Partly off topic - electronic slider

What's an "electronic slider"? Google suggests some kind of photographic equipment, as it's past lunch time, makes me think of tiny hamburgers..

So, you want a momentary-contact button to be replaced by solid state electronics? If a constant time-of-contact is what you envision, this would be a 'monostable', you'd want a NE555 or similar chip to do the task. Depending on your initiating event and the behavior of the 'return', there are lots of other options. There are lots of ways to generate a suitable trigger to start the button-down-like cycle.

The 'slider' word suggests a continuous range, but most 'button' actuators are attached to switches.

You might consider if you could preform some nitinol wire into a convex form (i.e., "button up") that the user could physically deform (button down). Then, when you want to "release" the button (return it to the "up" position), apply heat "momentarily".

The question doesn't make much sense - a slider that's a push switch to be operated by who knwos what, doing who knows what electrically? Ya, sure.

@Whit3rd

- i was thinking about some actuator like AS -03

@Don Y your idea in great am i will use it in one other project !

BTW. yep , slider was not a best word for this description. Sorry about that guys.

possibly, I don't see specs for that

The pwm commanded servos initially developed for radio controlled models seem popular with the arduino fans, just fit an arm or cam that presses the button.

Idea #101:

How about a variation on this:

which is a variation on this:

both of which come with a pedigree of long standing:
