Talking Rotisserie grid motor reverse with switches

I have a project i'm working on. Its a rotisserie basket grill that i want to rotate till it reaches a proximity switch (basket horizontal), stops and wait for a few seconds and rotates back to the same proximity switch (basket horizontal again). Waits the same amount of seconds and repeats the cycle.

At the moment i think i have a working drawing for it to rotate in the same direction. ** Will include this drawing **

This is for an 12vdc rotisserie motor. Proximity switch will be an 12vdc 3wire. And some 12vdc relays. 1x Toggle switch for the power. And an off-delay timer.

Any help with an updated drawing would be appreciated.

Thanks

Edit 1 : PS = Proximity switch, T1 = timer , R1 = relay and M = dc motor

I don't see any reversing wiring at the motor. All I see is one R1 contact to turn it on and off.
What is PS?

Hi Joed. PS is for proximity switch. The drawing i included is for it rotating in one direction only. R1 is for the proxy. So that i can give it an NO and NC contacts. ( The proxy has an NO only ).
Trying to figure out the reversing part of it.

So the proximity switch is connect directly across the 12 volt supply. It's going to blow the supply or the switch or both when it closes.

R1 needs to have multiple contacts so that when it flips it reverses the +/- power applied to the motor.

Welcome to the forums.

We'll call that a basic tutorial diagram. Your circuit will look nothing like that.
We know what you want.

You'll need an end sensor.
A logic state circuit that will alternately invert the output.
A timer.
A motor reversing circuit.

We'll work on some circuits for you.

Hi Pete. Thanks !

joed The supply voltage to the proxy is 12vdc, so only he signal voltage going to the relay R1.
