CONSTITUTION: A display button(50) comprises a pushing part(51) placed on a control panel installed on a front side of a main body of an indoor unit of an air conditioner to be pushed by a user; a pin(52) contacting with a rear side of the pushing part to transmit movement of the pushing part pushed by the user; an elastic member(53) supporting the pin, and having a tension structure; and a tact switch(54) pushed by the pin, and connected with a PCB(Printed circuit board:55). The tact switch converts the movement of the pin into electric signal. The elastic member returns the pin to original position after pushing the tact switch. A guide part(60) is formed on the rear side of the pushing part to guide the pin to contact with the rear side of the pushing part when the display button is operated by pushing the pushing part. The guide part has a plurality of triangular ribs on a circular circumference formed on the rear side of the pushing part to hold and guide the pin. |
