YES, the source of the problem!!
Before you throw any parts/money at a problem (common mistake made daily by many), find out first
what you need to replace.
The B/U circuit is one of the simplest. Diagram here:

If your turn signals work, that means the fuse is good (it is shared with the B/U circuit).
So at this point, you have only two possible points of failure:
- switch
- wiring
Unplug the switch connector. Put a testlight in the blue wire and turn the ignition on.
Does the test light light up?
No -> diagnosis: wiring problem between fuseblock and switch.
Yes -> continue below.
Insert a paperclip in the connector and turn the ignition on.
Do the reverse lights light up?
Yes -> diagnosis: bad switch.
No -> wiring problem between the switch and lightbulbs (possibly bad sockets).
Hope this helps.
