Abstract
Abstract A rheostat type of switch with a centrally pivoted switch lever, a plurality of spaced contacts on one side of the axis and an elongated circuit contact on the other side. A resilient contact strip carried by the lever engages, at one of its ends, one of the spaced contacts and, at the other of its ends, the elongated contact. When the lever is rotated to establish a new circuit, a cam means moves the contact strip away from all contacts.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
179 words
A switch including a housing, a printed circuit card in the housing and provided with two sets of contacts, one of which includes a plurality of separate spaced contacts at one end of the card and the other one of which includes an elongated arcuate contact at the other end to be connected to a selected one of the spaced contacts, a hub rotatably journaled between the sets of contacts for rotation within the housing, a switch lever rotatably journaled in the hub, and a resilient contact strip carried thereby, one end of the strip being retained in spring urged engagement with one of the sets and the other end of the strip having two positions, in the first position it is spring urged into engagement with at least one contact in one of the sets and in the second position it is under a bending stress in spring urged, spaced relation from at least one of the contacts in the other set, and cam means carried by the lever for effecting a selected one of said two positions.
Claim 2
Dependent Claim
179 words
A switch including a housing, a printed circuit card in the housing and provided with two sets of contacts, one of which includes a plurality of separate spaced contacts at one end of the card and the other one of which includes an elongated arcuate contact at the other end to be connected to a selected one of the spaced contacts, a hub rotatably journaled between the sets of contacts for rotation within the housing, a switch lever rotatably journaled in the hub, and a resilient contact strip carried thereby, one end of the strip being retained in spring urged engagement with one of the sets and the other end of the strip having two positions, in the first position it is spring urged into engagement with at least one contact in one of the sets and in the second position it is under a bending stress in spring urged, spaced relation from at least one of the contacts in the other set, and cam means carried by the lever for effecting a selected one of said two positions.
Claim 3
Dependent Claim
25 words
A switch according to claim 1 wherein the first set includes said elongated arcuate contact and the second set includes said plurality of spaced contacts.
Claim 4
Dependent Claim
19 words
A switch according to claim 1 wherein the card has a second elongated arcuate contact adjacent said spaced contacts.
Claim 5
Dependent Claim
50 words
A switch according to claim 1 wherein one edge of the housing has spaced slots therein and the switch lever has a projection which enters one of said slots when a circuit has been established and prevents rotation of the switch lever until a second circuit is to be established.
Claim 6
Dependent Claim
63 words
A switch according to claim 1 wherein the switch lever is mounted on a hub journaled for rotation within the housing, the hub having a radial opening to receive the lever which is rotatable on its own axis within the opening, the lever having a cam which in one position urges the resilient contact strip against one of the contacts on the card.
Claim 7
Dependent Claim
32 words
A switch according to claim 1 wherein a cam finger, slidably carried on the switch lever, engages one end of the contact strip to move it into spaced relation to a contact
Claim 8
Dependent Claim
25 words
A switch according to claim 1 wherein the first set includes said plurality of spaced contacts and the second set includes said elongated arcuate contact.
