I am a complete novice at this. Below I have images of the switch, wiring, and motor identification plate. I feel like this should be an easy one where I just cross wires on opposite ends, but I don't want to try anything and blow the motor or something like that. Can anybody out there give me some direction? Thanks in advance!

 

Here is the switch wireing. Cross connect outside terminals, connect one motor lead to one terminal, connect the other motor lead to the adjacent terminal. Connect the power source to the two middle contacts.

 

You need to disconnect the blue and yellow wires. Then connect the 'To Motor' wires from the diagram above to the blue and yellow wires and the 'To Power' wires from the above diagram to wherever the blue and yellow wires were originally connected.

 

The problem with using that DPDT switching arrangement is that you have no centre 'off' position. Flipping the switch (intentionally or accidentally) with the power on will try to reverse the motor instantaneously. That could be bad for the motor, the switch and possibly any bystanders! A motor of that size should be brought to a halt before changing direction.

If you look at the picture the switch has a center off position

 

The picture is ambiguous. The centre lines usually just denote the switch moving contact terminals.
From Wikipedia:

The switch should preferably be an On-Off-On type.

While most common DPDT toggle switches are wired internally like this:


and your wiring would look like either of these:

some switches aren't configured like that internally, so before you do anything else you should toggle the switch and measure continuity to find out what's what with the switch and how to wire it. Be VERY careful with AC mains since your life or someone else's could end if you do something wrong.

 

Very simple standard DPDT with centre off switch shown by the OP.
BTW if this is a typical small PSC motor where both coils are identical there is a way to do it with a SPDT Ctr off toggle switch.

Hi,

I did an actuator motor one time like this, but i used a DP3T switch, where the center position was 'off' and the other two were like a DPDT which gave me forward and reverse.

That said, some transient suppressors might be a good idea too to protect the contacts from repeated high voltage arcs when the motor is turned off.

If you study the photo carefully you'll notice that the toggle is normal to the legend plate, which means that it's in the center OFF position.

Do I detect a little sarcasm???

Surely, careful study isn't required to determine something as blatantly obvious as that.

Moreover, since it's entirely possible for the legend plate to have been installed erroneously, that's not a good indicator of whether the switch is ON - NONE - ON or ON - OFF - ON.

However, determining that the toggle has a center position - after a little careful study of the photo - makes it obvious that the switch can't possibly be ON - NONE - ON.

 

I must be missing something, the switch is labeled centre off and also appears to be sitting in that position.??
i.e. three position.

Indeed.

However, my initial post in this thread was in response to Alec_t's: "The picture is ambiguous. The centre lines usually just denote the switch moving contact terminals."

 

Ah, I was looking at the post #2 pic and hadn't zoomed in on the post #1 photo. Agreed, the switch in post #1 is centre off.

Elaborate, please?

The switch I have is On-Off-On
