Abstract
Abstract In a slide switch: a housing defining chamber; a slide movably supported by said housing within said chamber and fixedly carrying contact elements; said housing being composed of two pairs of elements, a first pair and a second pair; the elements of each one pair being identical but different from those of the other pair; the elements of the second pair being arranged between the marginal portions of said elements of the first pair; said elements of the first pair having inwardly projecting spring arms provided with surfaces engaging mating surfaces of said elements of the other pair and holding said elements of both pairs together as a rigid unit; elongated contacts supported on said marginal portions of the elements of the first pair and each having a resilient middle portion bridging the space between said marginal portions and adapted to resiliently engage said contact elements fixedly carried by the slide.

In a slide switch: a housing defining chamber; a slide movably supported by said housing within said chamber and fixedly carrying contact elements; said housing being composed of two pairs of elements, a first pair and a second pair; the elements of each one pair being identical but different from those of the other pair; the elements of the second pair being arranged between the marginal portions of said elements of the first pair; said elements of the first pair having inwardly projecting spring arms provided with surfaces engaging mating surfaces of said elements of the other pair and holding said elements of both pairs together as a rigid unit; elongated outer contacts supported on said marginal portions of the elements of the first pair and being abutted by marginal surfaces of said second pair, the outer contacts each having a resilient middle portion bridging the space between said marginal portions and resiliently engaging said contact elements fixedly carried by the slide.
Claim 3
Dependent Claim
28 words
The slide switch according to claim 1 wherein the outer resilient contacts have midsections making an acute angle with each other, meeting at and defining a contact surface.
Claim 4
Dependent Claim
52 words
The switch according to claim 1 wherein the outer resilient contacts are formed as punched out sheet parts and wherein said outer contact surfaces are square shaped where they are abutted by said slide carried contact elements, the margins of said square contact surfaces being bent off away from the contact surface.
Claim 5
Dependent Claim
16 words
The switch according to claim 1 in which the outer contacts are formed from wire sections.
Claim 6
Dependent Claim
30 words
Switch according to claim 1 in which said slide carried fixed contacts are secured in recesses in the slide by resilient projections fitting into the margins of the slide recesses.
Claim 7
Dependent Claim
27 words
The switch according to claim 5 in which said slide carried contacts are of wire and have essentially circular, or semicircular, or triangular, or rhombic cross sections.
Claim 8
Dependent Claim
35 words
The slide switch of claim 3 wherein each of said first pair of elements is provided along its marginal portions with studs integrally projecting therefrom, said studs passing through complementary recesses in said outer contacts.
Claim 9
Dependent Claim
62 words
The slide switch of claim 1 wherein each of the said first pair of elements is channel-shaped in transverse cross section, to thereby permit bending movement of the midportions of the said outer contact elements, and wherein each of said second pair of elements is provided with a ridge slidably engaging a complementary slot in the narrow, lengthwise surface of said slide.
Claim 10
Dependent Claim
36 words
The switch according to claim 5 in which said switch slide is rectangular in cross section and is provided on both its two narrow sides with a recess extending over the entire length of said slide.
Claim 11
Dependent Claim
44 words
The switch according to claim 5 in which said switch slide is rectangular in cross section and is provided on both its two widest sides with several contact carrying recesses extending in the direction of movement of said slide and being arranged in rows.
Claim 12
Dependent Claim
48 words
The switch according to claim 5, in which said switch slide is rectangular in cross section and is provided on both its two widest sides with several contact carrying recesses extending at an angle to the direction of movement of the switch slide and parallel to one another.
Claim 13
Dependent Claim
64 words
The switch according to claim 5, in which said switch slide is rectangular in cross section and said recesses are arranged on both widest sides perpendicular to the direction of movement of said switch slide and which are interconnected in pairs by recesses extending perpendicular to the direction of movement in the narrow sides of said switch slide, all the said recesses carrying contacts.
Claim 14
Dependent Claim
45 words
Switch according to claim 12, in which said recesses are arranged perpendicular to the direction of movement in the narrow side of said switch slide and in which said recesses are arranged alternately to one another with respect to the narrow sides of said slide.
