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:
- Domino 67
- Simis W
- Simis IS
- Thales Elektra 2
