Push switch structure for display
First Claim
1. A push switch structure of a display, comprising:
- an electrode substrate being capable of passing light therethrough and arranged on a surface of said display;
a key switch body having a transmissible portion for transmitting indication of the display when said key switch body is pushed, said key switch being arranged above said electrode substrate; and
an elastic sealing member adhering to a circumference of the key switch body, a base portion of the elastic sealing member cohering to said electrode substrate, so as to seal the key switch body and supporting the key switch body such that there is a space provided between the key switch body and the electrode substrate when the key switch body is in a non-pushed state, wherein the elastic sealing member is deformed in a pushed-state of the key switch body and resiles in the non-pushed state thereof thereby to form the space.

Abstract
A push switch structure for a display is provided, wherein the elastic sealing member 84 adheres to the periphery of the key switch body 83 for transmitting indication of the display 78. The key switch body is inserted into the opening portion of the elastic sealing member and the collar portion of the key switch body coheres to the elastic sealing member and is pressed with the cover. The key switch body is provided with the accommodating recess for a push-button switch 99. The key switch body is provided with the transparent electrode and the elastic sealing member coheres to the transparent electrode substrate arranged on the front of the display. An assembled unit 76 of the elastic sealing member and the key switch body is assembled to the display case 77, which is assembled to an assembly 96 of the control substrate 79 and the display. The elastic sealing member coheres to the front of the accommodating portion 87 and the display is put into close contact with the backside of the accommodating portion 87, and a part of the elastic sealing member is formed in a sector-shape between the key switch bodies and is bent to form the resilient portion. Thus, dust-and-waterproofing of the push switch for the display can be obtained.
