Thread: Automatic vacuum actuator

I would be interest in one too.

Carbatec sells one which you switch on with a remote control like an air-con, but you need a sparkie to wire it up and its over $190 ( I can't remember exactly how much it is).

Woodcraft has one for $35, but I doubt it would work here?

ANy sparkies out there have a similar solution?

Triton switch box planer.....thats what I have... three of them....

One on my drop saw.....when I switch them on the vacuum starts up....one on my saw-bench so the big overhead vacuum comes on....& on on my radio...as I switch that on the overhead filter comes on....helps not to forget to turn it off.....they are great...

Can you post a picture or some more details of where I can find this unit, I had a look at triton and had no luck? Perhaps a code number or something similar.

Thanks

Ok...I have the system where you have both vacuum & saw plugged into double point...behind that is the "triton planer" unit...I only have to switch the green button...and away she all goes....button is right next to bench so no reaching, no forgetting to turn off, safer as no-one realizes that the unit is on...unless they know the set up...... no worries....cheaper option than leckie...and completely portable & changable.....

Does anyone have australian based plans for a set up which turns on the dust extractor as soon as the table saw is switched on, and then when the saw stops so does the extractor, or ideally it continues to run for a few secs and then turns off.

Thanks

You just need to hard wire the two switches together. No need for an electrician for that, only it might void the warranty of the machines.

This is totally wrong!
This is the reason for an electrician because of advice like this.

Sprog, I totally agree.

Overload a powerpoint it is usually around the switch area that bursts in flames after a good bit of arcing (the contacts in the switch can't handle it).

Get a sparkie.

There are some automatic current sensing control units around. Might pay to look/post on a sparkies forum.

...close as I could get...camera can see better than me....Oh yes that's quite clear now.... & personally I'm glad I could help.

Yes I agree...use only the ones that are safe.....don't be foolish...with any botchy set ups....
I am wrapped with these....the best advantage is their safety...no-one can turn on my drop saw...unles they know about my little "green" switch....actually it's like a double safetly switch....because if they do find the switch....the vacuum starts up..they think they have the wrong appliance so they switch it off again....works like a charm.....so the moment I hear vacuum's I know what machinery is active....!!!

Cheer...good luck...hope you could read it all clearly enough....

thanks Kekemo

much appreciated

Ok...can't work out why my images are not thumbnail pictures....
Good-god....give me a sander....drop-saw or right now ....I wouldn't mind a chain saw...I know what I would like to do with this.....
cheers....

& HELP>>>>>>>

Redlaci,

I fed a bit of input into a similar discusion a couple of weeks ago where someone wanted to know if it was safe to hook a 2400W router into the auto switch port on a shop vac with a port rating of 2000W.

Now you haven't mentioned what vac/dusty you have or intend getting, or the table saw.

However, if you want to simultaneously switch them, their combined draw must be under 10A (2400W total) if they will be running off a 10A outlet, or under 15A if you have a dedicated 15A power outlet available. Remember that the circuit that they connect through will be fused to 16A, or have a 16 or maybe 20A breaker.

If the table saw is a low powered one (to 1HP) and the Vac/dusty is also limited to 1.5HP, it should be viable from a general 10A outlet. If either unit is more slightly powerfull, you will need to step up to a 15A dedicated outlet and wiring.

If you want to simultaneously switch a 3HP saw and a 3HP dusty, forget it, as they need independant dedicated 15A circuits, and there is no point in trying to bring the two power circuits together for switching, then split them out to the devices.

Hope this starts to explain the situation.

I resent this statement that I am giving incorrect advice without any evidence that it is so.

I have only stated that there is no legal obligation to involve an electrician to make a connection between two machines. We have already discussed this to death in previous threads. Whether you know what you are doing or need an electrician because you do not is another issue.

I expect an apology or evidence that what I say is incorrect.

"If you want to simultaneously switch a 3HP saw and a 3HP dusty, forget it, as they need independant dedicated 15A circuits, and there is no point in trying to bring the two power circuits together for switching, then split them out to the devices."

It can be done, it involves using contactors/relays in circuit to switch the dusty on.
I couldnt do it myself(Im not electrically smart enough) but my BIL who's a industrial sparky and a instrument fitter reckons its a pretty simple thing to do.
He just fitted a new relay to my dusty so I can switch it on from inside the shed(its outside...). He said all it takes is a another relay at the table saw switch box to activate the contactor on the dusty instead of physically pushing it.
Apparently you can get contactors that have switching options to delay start/stopping that are adjustable, but your getting into the expensive side of contactors as they are mainly designed for 415V control not 240V... Hell if your real smart you could use PLC's to control your whole shed's electrics by computer
