The invention provides a multifunctional combined terminal box current detection switch structure for field checking equipment. The multifunctional combined terminal box current detection switch structure comprises a base, a base cover and a pressing detection switch; a current connection terminal is arranged on the base; the current connection terminal comprises three current connection sub terminals arranged side by side; the detection switch is arranged between two adjacent current connection sub terminals to disconnect or connect the two adjacent current connection sub terminals; two connection grooves are formed in the lower part of one side surface of the detection switch; and the two connection grooves are connected with the current connection sub terminals. By arranging the pressing voltage detection switch on the current connection terminal, bolt use is reduced, and a bolt failure caused by repeated loosening or fastening bolts during voltage detection is avoided; and the current detection switch is pressed to be isolated from a circuit, so that live working of a tester is avoided, and the safety is improved.
