The invention provides a voltage detection switch structure for a multifunctional combined terminal box for electric energy measurement. The structure comprises a base and pressing type voltage switches, wherein voltage wiring terminals are arranged on the base; the voltage switches are arranged on the voltage wiring terminals to open or close circuits of the voltage wiring terminals; connecting grooves are formed at the lower parts of the two opposite side faces of the voltage switches; the two connecting grooves are connected with current wiring terminals; a switch button is arranged on theupper side face of each detection switch; and the switch buttons are pressed to control opening and closing of the two connecting grooves. Since the pressing type voltage detection switches are arranged on the voltage wiring terminals, the quantity if bolts used is reduced; failure in normal operation of the terminal box caused by bolt failure due to repeated loosening or tightening of the bolts during voltage detection is avoided; with the adoption of the pressing type voltage detection switches, the repeated operation of the bolts is avoided; and service lives of the voltage detection switches and the terminal box are greatly prolonged.
