Problems solved by technology

However, the light-shielding proposed here based on the light-leakage prevention flange 13b and the light-leakage prevention step 13c has structurally stepped gaps, so it cannot be completely light-shielded due to the irregular reflection of light.

Embodiment

[0022] When implementing the above structure, from the viewpoint of work efficiency, it is preferable to mount the two LEDs 2 and 3 on the substrate 8 before assembling the structural components. Therefore, the present inventors thought of a strong structure as shown in FIG. And in the assembled state, no light leakage occurs between the substrate 8 and the light shielding wall 4b. On the substrate 8 that is provided with a plurality of fitting holes 11 for fitting a plurality of wiring terminals 12 and partially provided with cutouts 13 for fitting two light-shielding walls 4b, LED2 and action display for night lighting are pre-installed. Used LED3. In addition, above the base structure 9 (in this specification, the direction of the operation button 1 is referred to as the upper side for convenience), two light-shielding walls 4b are arranged as an integral structure, and a plurality of dispensing walls 4b protrude upward. There are at least two wire terminals 12 and at lea...

Abstract

The object of the present invention is to provide a key switch, which realizes that the light from adjacent light sources arranged on the same substrate perpendicular to the direction of the pressing action and has different functions does not interfere with each other, and allows the pressing action and has good efficiency. Blackout construction. The key switch of the present invention has: LEDs arranged adjacently on the same substrate, two light-shielding walls erected with a gap between the LEDs, and one light-shielding wall installed on the back side of the operation button, the front end of the one light-shielding wall The above-mentioned two light-shielding walls have a positional relationship that fits in the gap between the two light-shielding walls, and the above-mentioned two light-shielding walls have a height that allows only the displacement of the one light-shielding wall during the pressing action of the above-mentioned operation button.

Description

technical field [0001] The present invention relates to an operation switch arranged on a panel of an automobile, etc., and particularly relates to a key switch device having a backlight function for distinguishing the position and operation state of the operation part for convenient operation at night. Background technique [0002] Among the key switches installed for operating automobiles and home appliances, there is a switch that is arranged side by side with a light for lighting and a light for indicating the operating status even in a dark environment such as at night. Since the lights displaying different contents are lit at close positions, if light leakage occurs between the two, it may cause false recognition, so a switch structure without light leakage is required. The present applicant has been engaged in the manufacture of a button heater control switch for automobiles as shown in FIG. 5 . This switch is a so-called push-button switch. When the driver presses t...
