Reversing mechanism of switch

Claim 2

In combination with a switch having a switch box, a movable see-saw contact and an actuating push rod, a reversing member made of normally flat, pliable elastic sheet material and formed in a generally rectangular shape substantially co-extensive in length with the length of said switch box, said reversing member having a central aperture receiving said push rod and being shiftable lengthwise of said switch box with said push rod to be deflected against the adjacent inner wall of said switch box to store energy for reversing said push rod.

Claim 3

A reversing mechanism as claimed in claim 1 wherein the reversing member has projections at both sides thereof, said switch includes a cover and said switch box has opposite side walls with notches, said projections being adapted to engage with said cover and rest in said notches to normally bow said reversing member when in said switch box.

Claim 4

A switch as specified in claim 1, wherein the length of said reversing member is substantially equal to a half of that of said switch box, said reversing member being arranged within said switch box, said reversing member being provided at its inner end with a semi-cIrcular recess engaging said push rod, said reversing member having projections at both sides thereof and adjacent said recess, said switch box having side walls with notches therein and said projections being adapted to engage with said notches of the switch box.

Claim 5

A reversing mechanism for switches comprising a reversing member made of a flat, pliable, elastic sheet material and formed in a generally rectangular shape, and having at an off-center position thereof an elliptical aperture for receiving a push rod of a switch, and said switch, including said push rod and a switch box having inner walls at a predetermined distance apart on each opposite side of said push rod, whereby said reversing member is shifted by said push rod toward one said inner wall or the other, to deflect said reversing member and store elastic energy for returning said push rod to neutral, central position.

Claim 6

A reversing mechanism for switches comprising a reversing member made of a flat, pliable, elastic sheet material and formed in a generally rectangular shape, and having at an off-center position thereof an elliptical aperture for receiving a push rod of a switch, and said switch, including said push rod and a switch box having inner walls at a predetermined distance apart on each opposite side of said push rod, whereby said reversing member is shifted by said push rod toward one said inner wall or the other, to deflect said reversing member and store elastic energy for returning said push rod to neutral, central position.

Claim 7

The combination of: a switch box having opposite end walls and opposite side walls jointly defining a cross sectional area of predetermined length and width; switching mechanism within said switch box including a movable see-saw contact and a push rod for tilting said contact, said push rod extending upwardly through the center of said area; a reversing member, operably connected to said push rod, said member formed of a normally flat piece of pliable, elastic sheet material, having a central aperture receiving said push rod and extending across said switch box from one said end wall to the other and substantially co-extensive in length therewith; said member being shifted sidewise with said push rod from a central ''''off'''' position toward an ''''on'''' position at either opposite end of said switch box and arranged to contact the adjacent end wall to curve in downwardly flexed form to store energy to return said push rod to central ''''off'''' position.

Claim 8

The combination of: a switch box having opposite end walls and opposite side walls jointly defining a cross sectional area of predetermined length and width; switching mechanism within said switch box including a movable see-saw contact and a push rod for tilting said contact, said push rod extending upwardly through the center of said area; a reversing member, operably connected to said push rod, said member formed of a normally flat piece of pliable, elastic sheet material, having a central aperture receiving said push rod and extending across said switch box from one said end wall to the other and substantially co-extensive in length therewith; said member being shifted sidewise with said push rod from a central ''''off'''' position toward an ''''on'''' position at either opposite end of said switch box and arranged to contact the adjacent end wall to curve in downwardly flexed form to store energy to return said push rod to central ''''off'''' position.

Claim 9

A combination as specified in claim 5, wherein: the side walls of said switch box include oppositely disposed notches in the upper edges thereof; said reversing member includes a pair of central projections arranged to be received in said notches; and said switch includes a cover member, clamped over said switch box to apply inward pressure on the ends of said projections and thereby normally bow said member while in said switch box into upwardly convexed form.

Claim 10

A combination as specified in claim 5, wherein: said aperture in said member is elliptical in configuration.

Claim 11

A combination as specified in claim 6, wherein: said member is formed in two halves, with said central aperture formed by a semi-circular recess in each half, whereby ease of assembly is accomplished.
