Sigmaguard LED ZS

Retrofit and long lifetime

Incandescent bulbs have a relatively short life and need to be replaced regularly, which results in high maintenance costs. In addition, incandescent bulbs are gradually disappearing from the market. In response, Siemens Mobility AG has developed a cost-effective, maintenance-free solution for LED retrofitting for the Swiss market: Sigmaguard LED ZS

Sigmaguard LED ZS is approved for the following interlocking systems in Switzerland:
