According to the present invention, an elevator fire operation switch comprises: a body which is installed on an outer wall of a reference layer in an elevator and has a through hole formed in the longitudinal direction; a limit switch installed in a lower portion of a bracket coupled to the body; a plug which is fixated to the through hole of the body to be rotatable and is rotated by a key; and a cam which turns the limit switch on/off by being coupled to one end of the plug and rotated integrally with the plug. A plate-shaped bracket is coupled to a fixing unit of the body; the limit switch is installed in a lower portion of the bracket; and the cam capable of turning the limit switch on/off is coupled to the outer side of the fixing unit of the body. Therefore, as the cam and the limit switch are vertically positioned, the size becomes smaller and the thickness becomes thinner, thereby reducing the installation space and providing easy installation.
