Possible to use a single foot pedal switch to activate a linear actuator? Answered

I acquired this mechanism which I would like to modify for ease of use.

The original set up uses a linear actuator and a 3 way toggle switch. The linear actuator comes with built in limit switches.
The 3-way toggle is not practical as my hands are fully utilised on the work bench.

I would like to modify the set-up so that I can use a single foot pedal switch to get this motion.
One step on the foot switch and the linear actuator extends to its maximum length.
Then another step on the same foot switch and the linear actuator retracts to its maximum.

Any help with the circuitry and parts will be greatly appreciated.

Thanks in advance.

ROY

Thank you all for the input.

Have solved the problem with the help of a friend.

Most appreciated.

What does the linear actuator do for you ?

Is it a resistor for some purpose ?

It is rigged to lift up a cantilevered table like platform.

And no, it is not a resistor.

Thanks

So you use the linear actuator to move a platform to a precision position that micro-switches cannot achieve ?

Why not 2 foot switches, one forward and one back? Simple circuitry.

Thanks for your reply NIck!

The base board where the toggle switch is currently located does not have much space for additional switches. I only have space for 1 switch which is why I am in the quandry that I am in.

A simple circuit I don't have to redraw, would have the thing going one way when the footswitch was pressed, and the other when it was release. Would that work ?

Thanks for your reply!

Unfortunately, I have to do work in between the the 2 phases so I cannot keep my foot on the switch for that long a period :-(.

You will need electronics for this or self locking switches that are connected to each other (very hard to find these days.)

Can be done with relays very easily

Would you be able to help with the circuitry layout and information?
That would be greatly appreciated. Thank you very much
