Abstract
Abstract A switch particularly for steering columns of automobiles for the selective operation of both light circuits and windshield wiper and washer circuits comprises a U-shaped spring contact having a first spring contact portion in a first plane and a second spring contact portion in a second plane. The switch includes a lever which is pivotal in both the first and second planes and which carries a rod member which may be engaged with the spring first portion to deflect it into engagement with a fixed contact for example for actuating a windshield wiper washer fluid supply circuit and which may be engaged during its pivotal movement for example in a vertical direction to move the spring second portion to engage a fixed contact which for example may operate a by-pass light circuit. The double spring contact actually includes the first spring portion which extends substantially vertical and at right angles to a horizontal portion. The switching lever is hollow and the rod portion is displaceable therein under a button control to engage one of the several spring contact portions.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
184 words
A switch, comprising a housing, a U-shaped spring contact in said housing having a first spring contact portion in a first plane and a second spring contact portion in a second plane disposed at an angle from said first plane, a switch lever, means disposed on and within said housing pivotally supporting said switch lever for pivotal movement in said first plane and said second plane, a first contact spaced from said first spring contact portion for operating a first operating circuit, a second contact spaced from said second spring contact portion for operating a second operating circuit, and a switching rod carried on said lever and being movable relatively thereto, said rod being displaceable independently of the pivotal position of said lever and having a rod portion engageable with said second spring contact portion to move it into engagement with said second contact and to permit disengagement therefrom, said lever being pivotal at least in one direction and having a lever portion engageable with said first spring contact portion to move it into engagement with and permit its disengagement from said first contact.
Claim 2
Dependent Claim
184 words
A switch, comprising a housing, a U-shaped spring contact in said housing having a first spring contact portion in a first plane and a second spring contact portion in a second plane disposed at an angle from said first plane, a switch lever, means disposed on and within said housing pivotally supporting said switch lever for pivotal movement in said first plane and said second plane, a first contact spaced from said first spring contact portion for operating a first operating circuit, a second contact spaced from said second spring contact portion for operating a second operating circuit, and a switching rod carried on said lever and being movable relatively thereto, said rod being displaceable independently of the pivotal position of said lever and having a rod portion engageable with said second spring contact portion to move it into engagement with said second contact and to permit disengagement therefrom, said lever being pivotal at least in one direction and having a lever portion engageable with said first spring contact portion to move it into engagement with and permit its disengagement from said first contact.
Claim 3
Dependent Claim
27 words
A switch according to claim 1, including a contact terminal mounted on said housing and connected to said spring contact between said first and second contact portions.
Claim 4
Dependent Claim
65 words
A switch according to claim 1, wherein said first spring contact portion is located in a substantially horizontal plane, said switch lever being pivotal to move a portion thereof through said plane to engage said first spring contact portion, said second spring contact portion being disposed in a substantially vertical plane with its longitudinal axis located in the horizontal switching plane of the switching lever.
Claim 5
Dependent Claim
62 words
A switch according to claim 1, wherein said lever comprises an angle shape lever having an offset outer end, said offset outer end having a bore, said switching rod being slidable in said bore and projecting outwardly at the lower end thereof adjacent the other portion of said lever in a position to be displaced to engage said second spring contact portion.
Claim 6
Dependent Claim
59 words
A switch according to claim 4, wherein said rod portion comprises one end of said switching rod, said rod having an opposite outer end with a push button thereon projecting outwardly from said lever, means biasing said lever to an off position, said push button being deflectable to deflect said switching rod to engage said second spring contact portion.
Claim 7
Dependent Claim
179 words
A switch according to claim 1, wherein said means pivotally supporting said switch lever includes a first set of pivotal bearings for pivoting said switching lever about a substantially horizontal axis so as to move the switching lever through a vertical plane, and a second set of bearings for pivoting the switching lever for movement about a vertical axis, said lever portion comprising a driver surrounding an end of said switching lever at a spaced location from said pivots having driver contact means thereon, said lever being shiftable in a horizontal plane to move said driver to move said contact, said housing having a plurality of stationary contacts arranged in the path of horizontal movement of said driver contact means for selective engagement therewith, said first spring contact portion comprising a spring disposed flat in a horizontal plane below said lever in a position to be moved by movement of said lever through a vertical plane, said second spring contact being disposed in a vertical plane being movable by displacement of said switching rod relative to said switching lever.
