  In this paper, the problem of stability in terms of two measures is
considered for a class of stochastic partial differential delay equations with
switching. Sufficient conditions for stability in terms of two measures are
obtained based on the technique of constructing a proper approximating strong
solution system and carrying out a limiting type of argument to pass on
stability of strong solutions to mild ones obtained by Bao, Truman and Yuan [
J. Bao, A. Truman,C. Yuan, Stability in distribution of mild solutions to
stochastic partial differential delay equations with jumps, Proc. R. Soc. A,
465, 2111-2134 (2009)]. In particular, the stochastic stability under the
fixed-index sequence monotonicity condition and under the average dwell-time
switching are considered.
