Abstract

An explosion-proof type switch box with an alarm is disclosed. The box has a window opening and push buttons are provided. An ampere meter and a switch are arranged within the box adjacent the window opening and the push buttons, respectively. An indication lamp is located on the upper face of the switch, electric lamps of green and red colors being mounted at the back side of the window opening and within the indication lamp and the lamps are connected in parallel with each other. The green lamps are set to light during normal operation of a machine connected to the switch of this invention while red lamps are set to light upon occurence of any abnormal condition in the machine. Thus, the operative condition of various machines can be determined at a distance with certainty.
