Welcome to Seismic Switch, the leading provider of Seismic Switches for over 35 years. We provide earthquake safety equipment primarily for the elevator industry, but also for other industrial applications. We are pleased to announce the CHV-2 is now UL approved!

Now you can help protect your passengers and elevators. Seismic Switch units can disable or deactivate any elevators which may become life endangering or self destructive during an earthquake. Our proven units are designed to reliably respond to only earthquake motions and to reject interference or false triggering from man made and non-earthquake motions.

We invite you learn more about our unique company and look forward to hearing from you to see how we can be of service!
