Light regulator switch

Claim 2

A light regulator switch comprising: a generally rectangular radiating plate (48) including a bent engaging member (84) at only one corner of the back side thereof and a hole (86) at another corner diagonally opposite to said one corner, a case (46) including detaining means (60) in and with which the bent engaging member (84) of said radiating plate (48) is vertically slid to be received and engaged, and a hole (58) adapted to be brought to alignment with said hole (86) of said radiating plate (48), said radiating plate (48) being rotatable relative to said case (46) about said detaining means (60) to bring said holes of said radiating plate and case into mutual alignment, and coupling means (104) fitted in the holes of said radiating plate and said case, whereby said radiating plate is securely coupled with said case.

Claim 3

The light regulator switch according to claim 1, wherein said detaining means 60 includes a detaining recess (61) having a pair of side walls (62) engaging side edges of said bent engaging member (84), thereby preventing sideways shifting of said bent engaging member (60) in said detaining recess (61).

Claim 4

The light regulator switch according to claim 2, wherein one of the holes of said radiating plate and said case is a threaded hole and the other is a through hole, and said coupling means includes a screw fitted in said threaded hole through said through hole.

Claim 5

The light regulator switch according to claim 2, further comprising an insulating plate (50) including a boss (70) with a plurality of engaging projections (72-75) formed on the outer periphery thereof and contained in said case, and wherein said radiating plate (48) has a slide hole (87) with notches (90) extending from said slide hole (87), said slide hole being loosely fitted over the boss (70) of said insulating plate with said projections aligned with respective notches, whereby said radiating plate is caused to engage behind said engaging projections (72-75) when said insulating plate (50) is vertically slid relative to said case after the loose fitting of said boss (70) within said slide hole (87).

Claim 6

The light regulator switch according to claim 4, wherein the boss of said insulating plate has two lateral engaging projections (72,73) protruding on both sides thereof, and the slide hole of said radiating plate is in the form of a vertically elongated ellipse having two lateral notches (90) within which said lateral engaging projections are received.

Claim 7

A light regulator switch comprising: a radiating plate (48) including a bent engaging member (84) at one corner of the back side thereof and a hole (86) at another corner diagonally opposite to said one corner, a case (46) including detaining means (60) in and with which the bent engaging member (84) of said radiating plate (48) is vertically slid to be received and engaged, and a hole (58) adapted to be brought into alignment with said hole (86) of said radiating plate (48), an insulating plate (50) contained in said case, said insulating plate (50) including a boss (70) having a least two lateral engaging projections (72,73) formed on the outer periphery thereof and protruding on both sides thereof, said radiating plate (48) having a slide hole (87) loosely fitted over the boss (70) of said insulating plate, said slide hole (87) of said radiating plate being generally in the form of a vertically elongated ellipse having two lateral notches (90) within which said lateral engaging projections are respectively received, whereby said radiating plate is caused to engage behind said engaging projections when said insulating plate is vertically slid relative to said case after the loose fitting of said boss (70) within said slide hole (87), and coupling means fitted in the holes of said radiating plate and said case, whereby said radiating plate is securely coupled with said case.

Claim 8

A light regulator switch comprising: a radiating plate (48) including a bent engaging member (84) at one corner of the back side thereof and a hole (86) at another corner diagonally opposite to said one corner, a case (46) including detaining means (60) in and with which the bent engaging member (84) of said radiating plate (48) is vertically slid to be received and engaged, and a hole (58) adapted to be brought into alignment with said hole (86) of said radiating plate (48), an insulating plate (50) contained in said case, said insulating plate (50) including a boss (70) having a least two lateral engaging projections (72,73) formed on the outer periphery thereof and protruding on both sides thereof, said radiating plate (48) having a slide hole (87) loosely fitted over the boss (70) of said insulating plate, said slide hole (87) of said radiating plate being generally in the form of a vertically elongated ellipse having two lateral notches (90) within which said lateral engaging projections are respectively received, whereby said radiating plate is caused to engage behind said engaging projections when said insulating plate is vertically slid relative to said case after the loose fitting of said boss (70) within said slide hole (87), and coupling means fitted in the holes of said radiating plate and said case, whereby said radiating plate is securely coupled with said case.

Claim 9

The light regulator switch according to claim 6 wherein said projections (72,73) extend a given distance away from said insulating plate (50), and said radiating plate (48) has a thickness less than said given distance.

Claim 10

The light regulator switch according to claim 6 or 7, wherein said slide hole (87) is located between said bent engaging member (84) and said hole (86) in said another corner of said radiating plate (48).

Claim 11

The light regulator switch according to claim 8 wherein said radiating plate (48) is rotatable relative to said case (46) about said detaining means (60) to bring said holes of said radiating plate and case into mutual alignment.

Claim 12

The light regulator switch according to claim 6 or 7 wherein said radiating plate (48) is rotatable relative to said case (46) about said detaining means (60) to bring said holes of said radiating plate and case into mutual alignment.

Claim 13

The light regulator switch according to claim 6 or 7, wherein said detaining means (60) includes a detaining recess (61) having a pair of side walls (62) engaging side edges of said bent engaging member (84), thereby preventing sideways shifting of said bent engaging member (60) in said detaining recess (61).
