momentary +12VDC on input to flip the polarity of +12VDC on output for 10 seconds

[TerminatorX5]

Hello.
I am new to this forum, and came here to ask the experts...

My issue -

input - momentary application of +12VDC to input wire should produce

output - (+) 12VDC on one output conductor and (-) on the other conductor for specified period of time (10-15 seconds, should be controllable)

input - momentary application of +12VDC to the same input wire should produce

output - (-) 12VDC on one output conductor and (+) 12 VDC on the other conductor fro specified period of time, reverse of the first momentary application, and should be time restricted, 10-15 seconds.

The purpose of this is to operate the power spindles - with one push of button, the spindles will spin in one direction for 10-15 seconds and then stop, with another push of the same button, the spindles will spin in opposite direction for 10-15 seconds and then stop.

I have tried SPDT, DPDT, timed relays, but I can't get it... I thought, if I can find a DP3T relay, i might accomplish something, but such a relay proved to be rather elusive.

Can anyone shed some light on this mystery?

thank you,

Welcome to ETO, Terminatorx5!

Simple, off-the-shelf, device (watch the PicoBoo FI-103 Introduction video to get the idea of how it works).: https://www.frightprops.com/controllers-electronics/frightideas-controllers/picoboo-controllers/picoboo-jr.html.

Then look at this example: **broken link removed**.

Of course, you could build such a device as you describe but, to be honest, it would cost as much, if not more, in the end.

Unless you're more interested in the building than the using... .

Thank you for the welcome, Cowboybob, really appreciate it.

It seems that the PicoBoo Jr. might be a feasible solution to the issue - I will study this further, and will let you know if something comes out of this idea.

thank you very much,
