DAVOS, Switzerland, Jan 26 (Reuters) - The Swiss franc is still too strong despite weakening against the euro in recent weeks but it is up to the central bank to decide on any action, Finance Minister Eveline Widmer-Schlumpf said on Saturday.

'I don't think euphoria is appropriate yet. We still need more movement, the franc is still high,' she told a news conference at the World Economic Forum in Davos.

'The central bank has its clear line and has held it since last year and done very well. It is important that politics doesn't get involved.'

The Swiss National Bank continues to keep all monetary policy tools at the ready to keep the still highly valued franc in check, Chairman Thomas Jordan said on Friday.

The SNB capped the franc at 1.20 per euro in September 2011 to stem safe-haven flows that had pushed it to record highs and threatened to tip the economy into recession.

Rising optimism about the outlook for the euro zone has seen the franc weaken in past weeks to trade around 1.24.
