Abstract
Abstract A lever switch for a vehicle windshield wiper having a base for attaching to a steering column, a rotational shaft rotatably connected to the base, a first switch knob connected to the rotational shaft, and a second switch knob rotatable mounted around a portion of the rotational shaft. The lever switch includes mounting the switch mechanisms for the first and second switch knobs around a portion of the rotational shaft, thereby allowing the rotational shaft to be shortened and the lever switch to be connected at an angle to the base.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
221 words
A lever switch comprising a base, a hollow bearing body mounted and secured to said base, a rotational shaft having a first end inserted into and rotatably supported in said hollow bearing body, a lever member fixedly mounted on said first end and having an arm bent to point along said rotational shaft, a slider receiver operably connected to said arm, said slider receiver being rotatably fitted on an outer periphery of said hollow bearing body so that said slider receiver is rotated upon rotation of said lever member, a slider disposed on said slider receiver, a first rotary switch knob fixedly mounted on a second end of said rotational shaft, a fixed knob portion fixedly mounted on the outer periphery of said hollow bearing body, a first selection mechanism provided between said fixed knob portion and said first rotary switch knob, a second rotary switch knob rotatably fitted on the outer periphery of said hollow bearing body between said fixed knob and said slider receiver, a second selection mechanism provided between said second rotary switch knob and said fixed knob portion, and a variable resistor provided on the outer periphery of said hollow bearing body between said second rotary switch knob and said slider receiver and being operated in association with the rotational operation of said second rotary switch knob.
Claim 2
Dependent Claim
221 words
A lever switch comprising a base, a hollow bearing body mounted and secured to said base, a rotational shaft having a first end inserted into and rotatably supported in said hollow bearing body, a lever member fixedly mounted on said first end and having an arm bent to point along said rotational shaft, a slider receiver operably connected to said arm, said slider receiver being rotatably fitted on an outer periphery of said hollow bearing body so that said slider receiver is rotated upon rotation of said lever member, a slider disposed on said slider receiver, a first rotary switch knob fixedly mounted on a second end of said rotational shaft, a fixed knob portion fixedly mounted on the outer periphery of said hollow bearing body, a first selection mechanism provided between said fixed knob portion and said first rotary switch knob, a second rotary switch knob rotatably fitted on the outer periphery of said hollow bearing body between said fixed knob and said slider receiver, a second selection mechanism provided between said second rotary switch knob and said fixed knob portion, and a variable resistor provided on the outer periphery of said hollow bearing body between said second rotary switch knob and said slider receiver and being operated in association with the rotational operation of said second rotary switch knob.
Claim 3
Dependent Claim
139 words
An improved lever switch including: a base for mounting to a steering column; support means fixedly connected to said base, said support means defining a through-hole; a rotational shaft rotatably disposed in said through-hole, said rotational shaft having a first end disposed adjacent said base and a second end projecting from said support means; a first rotary switch knob fixedly connected to said second end of said rotational shaft; and a second rotary switch knob rotatably disposed on said support means; the improvement comprising a first variable resistor rotary switch mechanism operably coupled to said first end of said rotational shaft, and a second variable resistor rotary switch mechanism operably connected to said first rotary switch knob such that said first and second variable resistor rotary switch mechanisms are disposed between said base and said second rotary switch knob.
Claim 4
Dependent Claim
139 words
An improved lever switch including: a base for mounting to a steering column; support means fixedly connected to said base, said support means defining a through-hole; a rotational shaft rotatably disposed in said through-hole, said rotational shaft having a first end disposed adjacent said base and a second end projecting from said support means; a first rotary switch knob fixedly connected to said second end of said rotational shaft; and a second rotary switch knob rotatably disposed on said support means; the improvement comprising a first variable resistor rotary switch mechanism operably coupled to said first end of said rotational shaft, and a second variable resistor rotary switch mechanism operably connected to said first rotary switch knob such that said first and second variable resistor rotary switch mechanisms are disposed between said base and said second rotary switch knob.
Claim 5
Dependent Claim
29 words
An improved lever switch of claim 2 wherein said first and second variable resistor rotary switch mechanisms are located between said first and second ends of said rotational shaft.
Claim 6
Dependent Claim
40 words
An improved lever switch of claim 3 wherein said support means comprises a hollow bearing body having a first end connected to said base, a portion of said first end defining a space between base and said hollow bearing body.
Claim 7
Dependent Claim
120 words
An improved lever switch of claim 4 wherein said first variable resistor rotary switch mechanism comprises: a lever member fixedly connected to said first end of said rotational shaft, said lever member rotatably disposed in said space, said lever member having an arm; a slider receiver rotatably disposed on said hollow bearing body and operably connected to said arm; a first slider fixedly disposed on said first slider receiver; and a printed circuit substrate fixedly connected to said hollow bearing body, said printed circuit substrate having a surface in sliding contact with said slider; wherein when said rotational shaft is rotated, said lever mechanism rotates said slider holder to slide said first slider across said surface of said printed circuit
Claim 8
Dependent Claim
102 words
An improved switch of claim 4 wherein said second variable resistor rotary switch mechanism comprises: a second slider receiver rotatably disposed on said hollow bearing body and operably coupled to said second rotary switch knob; a second slider fixedly disposed on said second slider receiver; and a base plate fixedly disposed on said hollow bearing body, said base plate having a surface in sliding contact with said slider; wherein when said second variable resistor rotary switch device is rotated about said hollow bearing body, said second slider receiver rotates to slide said second slider across the surface of said printed circuit substrate.
