  "abstract": "We present a comprehensive {\\it ab initio} study of the effect of higher-order anharmonicity and polymorphism on the lattice thermal conductivity, ${\\bm κ}$, of single-layer transition metal dichalcogenides. We show that four-phonon processes are responsible for an additional suppression of ${\\bm κ}$ ranging from 15\\% to 35\\% in the ground-state 2H phase. Conversely, their effect is almost negligible on the thermodynamically competitive \\1Tp\\ phase. The ${\\bm κ}$ difference between the 2H higher-conductivity phase and the \\1Tp\\ lower-conductivity phase can be exploited for the design of thermal switches that may find applications in thermal management and in the development of phonon-based logic elements, particularly in the case of tellurides, where field-controlled ultrafast and reversible phase transitions have already been demonstrated experimentally.",
