Question 3-Way light switch hookup issue

I am in the process of installing a new 3-way light switch. The old switch has 3 leads: back, red, and blue and NO ground? Anyway, the replacement switch has 1 black, 1 red, 1 blue, and 1 white - NO ground either. I know the white is the neutral, the black is "hot", and the other 2 are travelers.

Where does the white one connect to?

Welcome to the forums! It appears you may have picked up a 4 way switch. Post a picture of what you bought and we'll confirm. http://www.doityourself.com/forum/el...your-post.html

Standard switches normally have screw terminal. Is this some sort of electronic switch like Z-wave?

The new switch white goes to the house neutral. You might not have a neutral in the switch box.
If no neutral, the new switch cannot be used.
There are some electronic switches with batteries instead of a neutral.

It sounds like an application with no neutral present but it also sounds like a conduit wiring system which means a neutral may possibly be able to be pulled in.
