The Swiss Trusted List includes only recognised TSPs and only their services that meet the requirements (see section Rules for assessment of the listed services below).
The Swiss Accreditation Service (SAS) is responsible for publishing the Swiss Trusted List.
The Swiss Trusted List is available in a machine-readable format (XML) via the following link [lien]. A human-readable list (PDF file) of recognised TSPs is available on the webpage 

Description and Information about the National Recognition and Supervision Scheme

In order to issue regulated and qualified certificates within the meaning of the Federal Act of 18 March 2016 on Electronic Signatures (SR 943.03), trust service providers must first be recognised in accordance with the conditions laid down in the act, ordinance and technical and administrative regulations on electronic signatures (see section Rules for assessment of the listed services below). After recognition, the trust service providers are supervised to ensure that the provided trust services continue to meet the requirements.
The Federal Office of Justice (FOJ) and the Federal Office of Communications (OFCOM) set the requirements.
The accredited recognition body is in charge of recognition and supervision of the TSPs in accordance with the conditions laid down in the Federal Act of 6 October 1995 on Technical Barriers to Trade (SR 946.51) and the corresponding implementing provisions. The assessment procedures comply with the rules of the ISO/IEC 17021 standard. The recognition body is responsible for granting and withdrawing the qualified status for TSPs. KPMG Ltd is currently the only accredited recognition body.
The Swiss Accreditation Service (SAS) accredits the recognition bodies in accordance with the provisions of the Accreditation and Designation Ordinance of 17 June 1996 (SR 946.512). The SAS is responsible for publishing the list of recognised TSPs. The SAS establishes, maintains and publishes the Trusted List in collaboration with the Federal Office of Communications (OFCOM).
