Ada is a very expressive and robust programming language, chosen for applications where failure would result in catastrophic losses in terms of human life, economic damage, or major breach of security. Ada-Switzerland is a non-profit organization which promotes the use of Ada in Switzerland.

Please refer to the conference website for detailed information.

Ada has a long and successful track record in Switzerland in the development of mission-, safety-, and security-critical applications. A sample of some Swiss-based projects that owe much of their success to Ada are illustrated in the following slideshow images.

Ada-Switzerland is a non-profit organization and a member of Ada-Europe. It acts as a forum for persons and parties interested in the Ada programming language, its applications, and related technologies such as software engineering methods, development tools and bindings. The group promotes contacts and information among its members and interested parties. We organize meetings, seminars, conferences, and other activities related to our mandate which is to promote the use of the Ada programming language in Switzerland.


We currently offer two kinds of membership:
  1. Ada-Switzerland plus Ada-Europe membership for CHF 70 per year.
  2. Ada-Switzerland alone without Ada-Europe membership for CHF 20 per year.

Membership lasts from January 1st to December 31st.

If you wish to apply please contact us and provide the following details:

  • first name, last name
  • address
  • phone number
  • whether or not you want to become Ada-Europe member as well
The membership fees should be transferred to our PostFinance account 85-356348-7. Electronic payment is preferred.

Please not that in order to become a member of Ada-Switzerland you have to have an address in Switzerland. If you live outside of Switzerland and want to be part of the Ada community you should definitely have a look at the official list of national Ada organizations or contact the General Secretary.

Ada is an expressive and robust language in which the default for every programming construct is inherently safe. It was designed to allow programs to be engineered rather than crafted and that is why Ada is chosen for applications where failure would result in catastrophic losses in terms of human life, economic damage, or a major breach of security. Ada 2012, the latest revision, brought design by contract and support for multicore platforms to the language.
