EAU2 buttons & rose only. These are just the front part of the button and do not include the bellows.
For this product to be suitable, the little peg on the back of the larger button must be intact. It often snaps off and blocks the top of the hollow white stick at the bottom of the button housing. The peg on your new button will fit into the top of this stick and if it’s blocked there’s nowhere for the peg to go. If that's the case, you'll need the complete button, TS128.
