Hello,

Fairly specific to anyone who knows Dewalt tools or owns the DW735-XE Thicknesser/Planer.

At some point the power lever changed from the Red lever, to 2 discrete on/off buttons.

Just wondering if anyone knows when this happened or why it happend.

I have seen some used units purchased from maybe 2 years ago, with buttons, but 3 years ago they still had the lever.

Contacting Dewalt support resulted in them knowing nothing about the change - and it seems from what I have gleaned from other forums, that it is a NZ/AU change only... I cannot find any images online other than on Trademe.

Here is one:

Which is the 2 buttons.

Here is what everywhere on the internet shows as, with the lever:

Anyone have any information?

The buttons seem like a backward step...

Thanks in advance

Perhaps the 2 button switch is a type that releases on power loss so you can't plug the tool in and have it start immediately.

Id say that's unlikely, I have an eight year old DeWalt table saw (probably same generation as older planer/thicknesser) with the paddle/button arrangement and that restores to an off state when power is lost. It's a pretty standard safety feature and has been for some time

The red lever on the Thicknesser is not the same as the table saw. Its pull to turn on, and push to turn off. Its not a flap like the table saw which pushes on a stop button underneath, and you raise it up to expose the power button which you then push, to turn it on.

I cant work out why they changed the design to 2 discrete buttons.

As you say the table saw is a two button control with a flap covering the on button and operating the off button. Some workshops arrange a knee operated flap across the whole front of the saw stand to turn off.

Does the thicknesser with the flap default to off if you switch power off at wall? If not that will most likely be why they changed.
The AU manual showing the flap model refers to manually switching off on power loss and making sure it's off before plugging in so it is likely that it is a basic switch.

There was a great Tool Time tv episode when Tim plugged in a belt sander that took off trailing the extension cord.

I suspect because in some countries it is illegal to use the emergency stop / red switch to turn the power on...

Would then seem weird how every other country is still using the red lever switch, while only NZ and AU is using the buttons.

Could very well be that if the red lever is pulled out to Run and the cord is then plugged in, then it would immediately go - yes.

But still seems weird how only the AU / NZ model has changed to buttons then, and why everyone is is still the red flap.

I have no idea if the buttons automatically turn off when power is lost or not, as I have not opened by box yet. Its under the xmas tree waiting for the big day and for me to open it :)

yes the two button type is a magnetic switch and does require you to press the green button again after power loss (I got mine a couple of weeks ago)

My DeWalt table saw that I bought about 2yrs ago has the red lever. I've never tried to plug it in while the lever is set to the on position so don't know what would happen.

The colour of the push button switch actuator should meet the requirements of Electrical safety of machinery-Electrical equipment of machines –Part 1 General requirements (IEC60204-1).

For the start/connect function, the colour of the actuator should be white, grey, black or green. White is preferred, but red is not allowed.

This standard is applicable to NZ and AU and covers electrical machines that are not able to be moved while working (ie not hand tools)

I have seen some cheap imported tools with actual E-stops as the on-off switch (bench grinders) but that is an absolute no-no.

Not everyone, some Asian distributors are either showing 2 button version or the flap version photo with the switch location blurred.

For people looking for one of these, the technical term is no volt release (NVR) switches, based on their typical implementation with relays that open when power is removed, an early instance of encoding an implementation detail in user-visible things.

Do you have some URL's showing the units with buttons for me, of these asian distributors? I so far have failed to find any.

Thanks
