Abstract
A solid state seismic trigger switch has a tube, a first wire with a first end that extends into the tube, a soldered mass attached to the first end of the first wire, and a second wire in communication with the tube. The first wire and the soldered mass are suspended within the tube. The tube, the first wire, the second wire, and the soldered mass are conductive. The first wire and the second wire are electrically connected to a seismic recorder. Contact between the soldered mass and an interior wall of the tube closes an electrical circuit between the seismic recorder and the tube.
