Abstract
Abstract A potentiometer wiper assembly includes a housing with mounting means defining a plane and a rotatable resilient wiper carrying contacts extending below the plane. A stop in the housing contacts a flange on the wiper for limiting its arcuate travel. The wiper may be deflected into the housing and rotated to position the flange in overlying relationship with the stop. In this position the wiper contacts are above the plane, enabling the housing to be bonded to a substrate.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
119 words
A potentiometer wiper assembly having a housing adapted for bonding to a substrate and including mounting means defining a plane; resilient means movably mounted within said housing, said resilient means carrying a contact and normally urging said contact to a first position out of said housing below said plane; stop means in the path of movement of said resilient means; said stop means and said resilient means coacting to maintain said contact in a second position, within said housing and above said plane to permit bonding of said mounting means to said substrate; and means connected to said resilient means for releasing said contact to an operative position intermediate said first and second positions after bonding to said substrate.
Claim 2
Dependent Claim
119 words
A potentiometer wiper assembly having a housing adapted for bonding to a substrate and including mounting means defining a plane; resilient means movably mounted within said housing, said resilient means carrying a contact and normally urging said contact to a first position out of said housing below said plane; stop means in the path of movement of said resilient means; said stop means and said resilient means coacting to maintain said contact in a second position, within said housing and above said plane to permit bonding of said mounting means to said substrate; and means connected to said resilient means for releasing said contact to an operative position intermediate said first and second positions after bonding to said substrate.
Claim 3
Dependent Claim
62 words
A potentiometer wiper assembly as set forth in claim 1, wherein said stop means comprises an abutment in said housing and said resilient means has a projection for contacting said stop means and limiting travel of said resilient means; said projection adapted to be moved to a position overlying said abutment to raise said contact to said second position above said plane.
Claim 4
Dependent Claim
20 words
A potentiometer wiper assembly as set forth in claim 2, further including a control shaft coupled to said resilient means.
Claim 5
Dependent Claim
54 words
A potentiometer wiper assembly as set forth in claim 3, wherein said resilient means is rotatable within said housing; rotation of said resilient means in cooperation with pivoting of said projection enabling attainment of said second position; and wherein rotation of said resilient means releases said contact to assume said intermediate position after bonding.
Claim 6
Dependent Claim
27 words
A potentiometer wiper assembly as set forth in claim 4, wherein said housing is fabricated of conductive material and said contact is electrically connected to said housing.
Claim 7
Dependent Claim
26 words
A potentiometer wiper assembly as set forth in claim 5, wherein said mounting means comprise deformations in said housing at a plurality of circumferentially displaced points.
Claim 8
Dependent Claim
23 words
A potentiometer wiper assembly as set forth in claim 6, wherein said projection and said contact comprise opposed portions of said resilient means.
