The majority of the studies have considered a static scheme for the network. In this paper, the synchronization patterns of a time-varying network with discontinuous coupling (on/off links) are studied. At first, the prerequisites for the synchronization of continuous and discontinuous coupling are found by the master stability function method. It is observed that when the network with continuous coupling is set in the synchronous region, changing the coupling to a discontinuous one leads to the emergence of a pattern consisting of alternating synchronization, asynchronization, and chimera state. We call this pattern intermittent transient chimera. The study is completed by investigating the effect of the rate of discontinuity on the network behavior.
