Cistern push button

[opps]

Hi all,

I need to source a new push button for a toilet cistern.

It currently has a dual flush button on the ceramic "lid" that i very difficult to push down. On closer inspection I discovered that someone had replaced the push rods on the underside with screws. I assume that the rods snapped at some time.

I can't quite work out why the lid has a dual flush button, the cistern seems to be a single flush.







The original was branded as an Armitage Shanks, will a generic single push button suffice? Additionally, when I push down on the white disk in the last image, it take a bit more pressure than I would have thought normal. Is there anything that could be helped with a dab of silicone grease?

Thanks in advance.

Some short flush by holding button in until water stops while long flush is push and let go.

Thanks Wayners, that doesn't explain why there are two buttons though.
