Hi all,
As of the below picture this is how you would change a motors direction using a DPDT switch.
If the switch is in the centre position nothing happens and it is off. If the switch is in the forward direction it makes the motor to go in one direction and if you move the switch backwards it makes the switch go in the other direction.
Here is what I am trying to acheive and have been drawing things for 3 hours now and its driving me potty
I have a perm -, perm + and a switched +
When the switch is in the middle position I would like it to make the switched + only so the device controling it can switch the motor in a reverse direction on command
When the switch is in the forward direction I would like it to make the perm + only and cause the motor to go in forward direction
When the switch is in the backwards position I would like it to make the perm + only and make the motor go into reverse
In effect if I wire it as of the above drawing but have the perm - also going to the - of the motor directly and have the switched + also going to the + of motor this would work but when I move the switch into the forward or backwards positions it would cause a dead short between + and - if the switched + is on at the same time.
I would like the switch to flick back to the centre point when I let go of it after holding it in the forward or backwards positions.
Can anyone point me in the right direction of a suitable switch please. The perm +, switched + and permanent - is all the wires I have and I dont want to add more cores.
The motor load (8 x 12V motors plugged into a junction box) is 1.8A per motor = 14.4A so I will need a 15A rated switch
Thanks
