Abstract

An indication device of an electric switch comprises an indication component (101), a driving component (103) and a positioning component (102). The indication component (101) has at least three indication positions. Each indication position corresponds to one state of the electric switch, and the indication component (101) shows one indication mark at each indication position. The indication device of electric switch uses a single indication component (101) having at least three indication positions, and the third position is provided via deformation of the indication component (101) itself, thus realizing a simple structure and low manufacturing cost.
