Can 3-way dimmer be used as single-pole switch?

I have a Lutron DV-603P 3-way dimmer switch. The dimmer function is on a slider separate from the on/off function. It seems that it is possible to simply connect incoming power to the Common terminal and load power could come from either of the other two (red) leads. The remaining (3rd) wire would have no connection.

Of course that means that when the switch is flipped, the unattached 3rd wire would get energized. Since there are lots of energized wires in there anyway, on the surface it seems harmless to put a one-wire wire-nut on the 3rd wire and call it good.

Would this work? Would it be safe & to code?

Thanks!

It is fine (code) to use a single pole switch instead of a 3-way but you may not be able to get rid of the box of the unused 3-way easily. If you have both the hot and the switch leg in the box that you want the single pole then your in luck. If not, then you will have to do some rewiring and maybe just put a blank plate of the unused switch.

Yes, you can use a three way switch (even a 3 way dimmer) in place of a regular switch. Place a wire nut over the unused wire.
