Two-way back driven electric switch
Two-way back driven electric switch
(OP)
I am curious if anyone knows of a two way mechanical switch that can be manipulated via a person and an electrical signal?
I want to be able to activate the switch but back drive it to reset it if no user is present too. I can clarify and my apologies if I have missed a detail. Thank you in advance!

What is the switch for? On machinery a latching relay might do what you want. One button would energize the circuit and another button will open it. Google latching relay circuit.

I am looking for a switch similair to this: http://www.xurui-electronic.com/9-toggle-switch/1-...
It is for a technology demo. We want a user to be able to throw the switch and sense its position however we also want to ability to change the switch via a computer. Does that make sense?

In my field it's not really practical to use a motor to operate a switch, this would add unnecessary expense to the process.
Since you also would like remote computer control this complicates things further What you propose would
best be done with a PLC (programmable logic controller) or relay logic since voltage difference
and communication between your switch and computer input might be substantially larger this would require
rather elaborate circuitry in between switch and computer. I don't know of any switches available like you
describe, otherwise Scotty's solution is expensive but might be the best. Possibly someone else has a solution.

From a practical perspective I completely agree that this is not the way to do it. My problem is I'm going for a "Disney" type solution in that the user can manipulate the toggle but I can back drive it too. Hard to explain in full here but I'm hoping I'm giving enough information. Thanks in advance to everyone!

Edit:
I found these. The solenoid only works to reset the switch after being manually engaged.

"solenoid operated toggle switch". Looks as though they have many military and aviation applications."You measure the size of the accomplishment by the obstacles you had to overcome to reach your goals" -- Booker T. Washington

I think both the one I linked and the one jraef linked in the post above are bi-directional. I've attached a proper datasheet for the Acti 9 unit. It appears to be bi-directional unless it trips on a fault, which makes sense to me.
jraef - that looks very busy inside that MCB casing!

Or simply use the switch status as an input to the PLC and have the PLC do whatever you want it to, whether the user is activating the switch or not. This may be appropriate if it is not a safety-critical application.

When the actor flips the dummy switch, the scene supervisor (watching) presses the real button that actually makes something happen (remotely) ... When the dummy switch needs to move on its own for the camera, the solenoid underneath the panel/faceplate moves it when the scene supervisor presses the (remote) button that activates it ...
