A new apparatus for detection of nu(mu) --> nu(tau) oscillation has been successfully constructed and operated by the CHORUS Collaboration for the CERN-WA95 experiment. The design, implementation and performance of the electronic trigger system is described. A trigger efficiency of 99% was measured for nu(mu) charged-current events and 90% for neutral-current events.
