Table saw switch

[Andy5678]

Looking to replace a table saw switch. The saw has a slow start motor, so the usual retrofit start stop switches won’t work.

Anyone ever replaced one/recommend a retrofit switch?

Andy would a selector switch work ?

It would be an HOA selector switch with on-off-automatic

 

[Andy5678]

No, it’s just on and off. Red and green buttons.

when started it runs slowly then changes to full speed

Are you sure the switches are the source of the problem and could they not be standard panel mount and working a soft start unit? Do you have any spec or pictures of the saw at all?

 

[Andy5678]

No pictures. Had the switch open, it has a coil
In it, when the start button pushes down into it. It has 3 cores and earth going into the motor. Switch is defiantly faulty as it’s seized and melted at the base.

 

[SparkySy]

Ah I see, no mistaking that then! Sorry bud I wouldn't know where to get a replacement or similar, I take it googling the make and model is not bringing anything useful to light?

 

[Andy5678]

Found the right switch but it’s expensive and probably better getting a new saw. But if other switches are available, it would be a better option to replace.

how expensive is "expensive"

Just how many terminals are on that switch, it sounds like it is opening and closing the load of the motor not the wiring going to the coil which starts the motor

The switch should be turning on and off the controls not the actual motor load. Most switches are not designed for that much current

Ok megawatt, can’t remember how many terminals.

Andy we are just trying to help you and your problem. Good luck

It sounds like it might be a star delta starter to me. If so, get an experienced electrician to sort it out.
edit. Are you sure about the number of cables involved?

 

[Mike Johnson]

Is the motor three phase or single phase, if single phase the slow start is in the motor/outside the switch and any NVR switch will work.

 

[Andy5678]

Think I will open up the motor and check where these cores go to

Andy good luck and hope you get it fixed

Will update soon MW

Been back and checked the motor connections. Looks like the slow start is switched at the switch?
