Claims

[Scope of claim for utility model registration] (1) A detection coil and a detection circuit are housed in a box-shaped case.
In the proximity switch, the case is sealed and the cables forming the power supply line and the signal line are taken out from the detection circuit to the outside, and the case is coated with a light diffusing agent having an arbitrary width and reaching at least the top plate and the side walls. A display window made of a translucent or opaque synthetic resin and an opaque other part made of an ordinary synthetic resin are integrally molded, and a light source is disposed below the display window. switch. (2) The proximity switch according to claim 1, wherein the display window is provided with a recess for accommodating a light source. (3) The proximity switch according to claim 1, which is a registered utility model and is formed by inserting a light source into the display window and integrally molding the same.
