The electronic roll-along switch consists of several input multiplexers, each having a number of inputs that are connected to seismic detectors, and an output line. A plurality of multiple-input sample-and-hold modules are provided. Corresponding inputs of the respective sample-and-hold modules are paralleled. The output lines of the input multiplexers are connected in consecutive order to the paralleled input of the sample-and-hold modules. The output of each sample-and-hold module is connected to an output amplifier which is couplable to a multichannel seismic recording system. A master controller provides circuitry for connecting any set of several seismic detectors to a like number of channels in the seismic recording system.
