240 volt light timer?

I'm in the process of remote mounting my led drivers outside of my grow room as well as any related timers. I would like to use a simple mechanical wall mount timer like this. https://www.amazon.com/dp/B0040R97I0/ref=psdc_6291360011_t2_B00UVCKKLG
Because it only switches one leg of the 240 circuit, will the other live 120 leg cause the driver to still attempt to operate? I'm just trying to avoid using a big clunky irrigation timer.

I cant understand what youre asking but just to bump. Im on 220V and i used a cheap 110V mechanical timer and it worked fine. I did for like a year before I thought about it, when it was "ON" it got very hot. I have a feeling a lot of these things are over designed and will work either way, but you should get the proper stuff asap.

Just get a digital one. $14 on Amazon.

There is a Titan Controls 240v digital timer on Amazon for $18.53

Again, thanks for the replies. I'm aware of the Titan and Intermatic timers for 240v-they all only switch one of the 120v legs of your 240v feed leaving a single 120v wire that's still energized. I'm just trying to make sure that as long as I have the switched circuit connected to line in(brown wire) and the other side of the 240 circuit connected to neutral(blue wire) the driver won't have any weird back feed through the ground circuit.

just use a sonoff like the rest of us
