    • A light guide part (20) is provided along a Z-axis on a side surface of a case (2) of a relay (1). The light guide part is a thick portion formed of a material forming the side surface of the case, and is structurally integral with the other parts of the case. Also, a light emitting device which emits light in response to application of a voltage to coil terminals (41) is provided within the relay (1) (case). A reflection surface (201) which reflects illuminating light emitted from the light emitting device in a (+Y) direction in a (+Z) direction is placed at a lower end of the light guide part. Illuminating light reflected by the reflection surface is guided to a display surface (200) placed at an upper end of the light guide part, to illuminate the display surface.
    • 沿着Z轴在继电器(1)的壳体(2)的侧面设置有导光部(20)。 导光部是由形成壳体的侧面的材料形成的厚壁部,与壳体的其他部分构成一体。 此外,在继电器(1)(壳体)内设置有响应于向线圈端子(41)施加电压而发光的发光装置。 在(+ Z)方向(+ Y)方向反射从发光装置发出的照明光的反射面(201)配置在导光部的下端。 由反射面反射的照明光被引导到放置在导光部的上端的显示面(200),照射显示面。
