From the Swiss Federal Department of Foreign Affairs, 15 July 2006:
Today, following the expiry of the deadline for holding a referendum, Switzerland has deposited the ratification instrument of the third Protocol additional to the Geneva Conventions of 1949, relating to the Adoption of an Additional Distinctive Emblem. With this second ratification (after Norway), the third Additional Protocol can come into force.

Switzerland signed the third Protocol additional to the Geneva Conventions on 8 December 2005, the day it was adopted by the Diplomatic Conference of the High Contracting Parties in Geneva. The Additional Protocol creates a distinctive emblem in addition to those already in existence, i.e. the Red Cross, the Red Crescent, and the Red Lion and Sun. The new emblem takes the form of a square red frame standing on one corner against a white background. The International Conference of the Red Cross and Red Crescent decided on 22 June 2006 that the additional emblem would be called the "Red Crystal".
Switzerland has today deposited the ratification instrument of the Third Additional Protocol, following the expiry of the period in which a referendum can be held. With this second ratification, the Third Additional Protocol will enter into force in six months’ time.

Since work started on the new emblem, Switzerland has been actively involved in the development and the adoption of the Third Additional Protocol, the purpose of which is to determine a global and lasting solution to the longstanding emblem question. The Federal Department of Foreign Affairs is therefore pleased that Switzerland has been able to contribute to its entry into force.

The new emblem is an attempt to overcome controversy over the Magen David Adom emblem from many Arab countries by tracing a neutral and international emblem.
