Abstract

In order to provide a small push button switch that can arrange the display part and the light source close to each other with a simple structure and can efficiently illuminate the display part, it is provided with: A display portion is formed on the upper end, and an insertion hole facing the through hole is formed on the bottom surface. The light source is accommodated in the insertion hole and the through hole; the through hole is formed in a linear shape along the pressing direction. Alternatively, in order to provide a miniaturized push button switch, it is provided with: a housing with a pair of fixed contacts extending in parallel along the pressing operation direction; a movable contact part held on the above-mentioned operation shaft and elastically The component is elastically biased, and is provided with a movable contact composed of a pair of protruding parts that are respectively in elastic contact with the above-mentioned fixed contacts; the contact-separation guide part is provided on the above-mentioned housing, and is in the closed position following the pressing operation. The upper portion is in contact with a portion between the pair of protruding portions, and the movable contact is separated from the fixed contact.

Description

technical field [0001] The present invention relates to a push button switch having an illumination structure for locking a power window or the like. [0002] In addition, the present invention also relates to a push button switch in which a fixed contact member is provided on the inner surface of a casing, and a movable contact member is provided on an operation shaft that can be contacted and separated from the fixed contact member. Background technique [0003] As a push button switch with an illumination structure, the structure of the first conventional example shown in Patent Document 1 is known, such as Figure 9 shown. [0004] As shown in this figure, the push button switch is made of the following parts: a button 21 with a light-transmitting display portion on the front; an escutcheon 23 of opaque material that is inserted into the button hole 22 of the button portion 21; A printed circuit board 25 of an opaque material with a switch 24 operated by the button 21 o...
