Abstract
A multi-stage push button switch device includes a plurality of first and second push button members fixedly coupled to a base plate. Each first and second push button member includes a button portion having a flexible arm portion extending therefrom. The end of each flexible arm portion remote from the button portion is coupled to the base plate. The flexible arm portions of the second push button members are longer than the flexible arm portions of the first push button members, whereby the button portions of the second push button members are supported at a greater distance from the base plate than the button portions of the first push button members. The first and second push button members have working pieces protruding therefrom and movable in response to a pushing of the associated button portion to push and thereby actuate an associated switch. The switches are disposed relative to the push button members such that those switches associated with the second push button members are at a distance therefrom greater than the distance between the first push button members and the switches associated therewith.
