Abstract

PURPOSE:To facilitate manufacture and achieve an illuminated rubber contact having high class feeling by molding a hollow light blocking portion having the same shape as the side faces of a key top in a metal mold and then further carrying out molding integrally with rubber used for a contact body. CONSTITUTION:A hollow light blocking portion 1, molded beforehand from a light blocking material such as colored silicon rubber, etc., in the same shape as the side faces of a key top, is inserted into a key top molding portion of a metal mold 2, then a silicon rubber ground 3, the material of a rubber contact body, is inserted thereby and the metal mold is closed to mold it intergrally with the side face light blocking portion 1. After this molding, an illuminated rubber contact 10 is made by printing a predetermined letter, etc., 7 on the key top surface with silicon ink such that the portion of the letter, etc., 7 to be lit is not covered with the ink. An illuminating LED 9 is erected from a bottom substrate 4 in a space 6 within the rubber contact 10 so that the light from this LED is transmitted through the portion of the letter, etc., 7 to light it. Thus, high class feeling can be given to the rubber contact 10.

Conventionally, the light is not blocked, so the entire contact part shines, making it impossible to achieve a luxurious look. Although printing with a light-shielding material such as silicone ink can be considered, it is extremely difficult to mechanically print shapes such as cylinders, domes, or rectangles.

During molding, it is first inserted into a mold, and then molded integrally with the contact rubber body.

［実施例］ 次に図面に示す実施例に従って本発明を説明する。[Example] Next, the present invention will be explained according to embodiments shown in the drawings.

等７を抜いた印刷を行ない照光式接点ゴムを製作する。A hollow light shielding part 1 made by molding a light shielding material such as colored silicone rubber in advance according to the side shape of the key top is inserted into the key top molding part of the mold 2, and then molded with the material of the contact rubber body. A certain silicone rubber dough 3 is put in, the mold is closed, and the mold is integrally molded together with the side light shielding part 1. After molding, the key top surface is printed with silicone ink 5 with predetermined characters 7 to be illuminated removed to produce an illuminated contact rubber.

An LED 9 for illumination is placed upright from the lower substrate 4 in the space 6 in the contact rubber 10, and this light is blocked by the side light shielding part 1 and the light shielding printed part 5 on the "r-1-" tab surface. Only parts 7 such as letters on the top surface are transmitted and illuminated. 8 is a housing.
