An automatic switch includes a main body having a circuit board provided therein, and at least two sets of connectors connected to the main body via signal cables. The main body has an integral enclosure formed through multiple times of injection molding to include a circuit-protecting layer for enclosing the circuit board, an outer case enclosing the circuit-protecting layer, and an anti-slipping layer coating an outer surface of the outer case.
