Need some electrical help

Alright, so trying to put together a controller for a project I'm working on. Basically, what I need to happen is to be able to push a button on a momentary switch, and perform 2 actions with 1 push of the button, then be able to do the same thing in reverse order.

So essentially, the order goes something like this:

1) Push and hold button
2) Begin action #1 and run through action 1's full cycle
3) Once action 1 is finished, begin action #2 until finished
4) Release button

Also would need to do the same thing, just in reverse, from the same switch, but using a different button.

So,
1) Push and hold button #2 (essentially the other side of a momentary rocker switch)
2) Begin reverse of action #2 until complete
3) Begin reverse of action #1 until complete
4) Release button

I'm no electrical engineer, but in my mind I need some kind of 2 or 4 stage relay of some kind, but not really sure where to start. Any ideas?

I'd also be good with just pushing the button once (without holding it) and letting it cycle through both actions automatically. Either way works for me.

Do the actions have a varying time frame or are they constant in time requirements?

The time required for action 1 and action 2 are different, however the time to complete action 1 will be a constant, and time for action 2 will always be a constant as well.

Is there feedback (contact changing state) when each operation is complete?

Sounds like you are definitely going to need some kind of control box and some programming for this. Talk with Tr6coug. I'm sure he has the skills and knowledge to get you where you want to be.

Not yet, but I'd consider adding it if needed. Would take slight redesign of the project, but nothing we couldn't add in. Keep in mind, all components added to this project require extensive exposure to the elements, so they'll be in a harsh environment. The fewer electronics, the better.

You could do a simple push button latch to relay to timer to relay to timer again. I can draw the schematic up when I have a second and post it.

Never mind, poor idea sorry about that.
