ABSTRACT:
A display type push button having a push button body with a display window on the front end, a passage formed therein, and an elastic display plate laid in the passage in such a manner as to reciprocate along the passage to display the "on" and "off" states of a switch coupled to the push button, comprises a mechanism which makes the movement of the display plate larger than the stroke of the operating rod of the switch, whereby the area of the display plate appearing in the display window is large enough to clearly detect the operations of the switch.
