Embodiment Construction

[0032] Below, will target Figures 1 to 6 The embodiments illustrated in describe the invention, Figures 1 to 6 Forms part of the Examples.

[0033] like figure 1 As shown in , the dimmer 1 is assembled to the panel 2 via a coupling frame (not shown). The panel 2 is in the shape of a rectangular plate and has an exposure hole 2a formed in its central area. The dimmer 1 is fixed to a wall (not shown) or the like in such a state that its front surface is exposed to the outside through the exposure hole 2 a. Furthermore, the front surface of the dimmer 1 forms a rectangular shape when viewed from the front side. In this embodiment, the dimmer 1 is fixed in place in such a way that its shorter side extends horizontally.

[0034] refer to figure 2 and 3, the dimmer 1 includes a box-type case 5 formed by a front cover 3 and a rear body 4, an operation knob 6 provided on the front surface (cover 3) of the case 5, and a plurality of circuits housed in the case 5. The circuit ...

Abstract

The invention relates to a dimmer, which comprises: a box shaped shell having a cover and a main body coupled to each other by an alcula and an alcula container; an operation knob disposed on the front surface of the shell; and multiple circuit devices contained in the shell. The circuit devices form a lightness regulating control circuit used for responding to the knob operation to regulate the lightness of the light loads. A pair of coupled concavo part and convex part are disposed on the cover and the main body near the alcula and the alcula container; and the cover and the main body can move relative to each other at least in three of the four orthogonal directions by limited observation in the front-rear direction while the cover and the main body is coupled.

Description

technical field [0001] The present invention relates to dimmers for adjusting the brightness of lamps such as incandescent lamps. Background technique [0002] Conventionally, a dimmer is arranged between an AC power source such as a commercial power source and a lamp such as an incandescent lamp to perform a dimming operation of a lamp load, an example of which is disclosed in Japanese Patent No. 3700329. [0003] The dimmer includes a box-shaped housing, an operating knob arranged on the front surface of the housing, and a plurality of circuit devices accommodated in the housing. The circuit devices constitute a dimming control circuit, and the dimming control circuit is used to operate the operating knob. Adjusts the brightness of the lamp load. The housing of the dimmer includes a front cover on which an operation knob is provided and a rear body. The front cover and the rear body are coupled into a box-like shape through their claw portions and claw receiving portions...
