Abstract
A seismic sensor is disclosed which essentially consists of a central annular member having an inner conductive periphery. The annular member is coaxially positioned around a center post located in a housing. The center post has four extending surface slots into which are inserted tines or upstanding flanges associated with first and second contact members. The contact members enable the sensor to be mounted in four distinct positions, thus giving the installer great flexibility.
