This one one says Harmony pushbuttons and switches. XB4 series is different from this. Thats what I thought. So the contactor blocks for XB4 series wont work with this. That was my assumption. Am I wrong.

The XB2B range of PB was originally designed and sold by Telemecanique, since then Group Schnieder have taken them over.
You require to order the PB/SW, switch body and N.C. or N.O. switch unit.
It appears they have changed the name or come up with an alternative product (Harmony?).
I have used the XB2B versions extensively in the past,
Also I see these are sold on ebay from China, considerably cheaper, probably knock off's ?
The XB2B and ZB4B do not appear to be compatible/interchangeable ?

The XB4 requires only 1 screw to tighten on the mounting collar verses 2 on the XB2. This allows easier installation. The XB4 push buttons can accept 3 contact blocks side-by-side-by-side for a total of nine contacts on non-illuminated devices. Using the XB4 Protected LED light modules and contacts on each side will allow shallower depth than the XB2 on illuminated devices.

also, note to topic starter, you can scroll down on those Farnell pages and see related parts. part number for the contact is right there. documentation or catalog will show you the rest. also Schneider makes it possible to order assembled buttons/indicators (single article number for combos like pilot + lamp+ contacts). they have them in button boxes too
