Abstract
Abstract A multi-pole switch includes a wobble stick type actuator provided with a contactor engaging the free end portions of a plurality of displaceable resilient inner pin contacts having their base portions fixedly mounted in a support member. A plurality of stationary pin contacts are disposed radially outside and adjacent said displaceable pin contacts. A guide member adjacent the contactor includes a plurality of radially extending slots therethrough each housing a portion of one of the displaceable pin contacts and one of the stationary pin contacts in a normally spaced apart manner. A biasing element normally maintains the contactor in a central, neutral position whereby, upon deflection of the actuator the contactor is radially displaced and correspondingly displaces a selected inner pin contact into engagement with its radially adjacent stationary pin contact in the same guide member slot to close a circuit between the engaging contacts.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
175 words
A multi-position switch including, a shell having a central throat in a front end, a support member within the opposite rear end of said shell, a plurality of stationary contacts disposed longitudinally within said shell, a plurality of displaceable contacts spaced adjacent and radially inwardly of said stationary contacts, said stationary and displaceable contacts having base portions fixedly disposed in said support member whereby the opposite free end portions of said radially adjacent contacts are normally maintained in a spaced apart manner, a guide member axially adjacent said support member and provided with a plurality of substantially radially extending slots throughout its length, portions of radially adjacent pairs of said stationary and displaceable contacts disposed within each one of said slots, an actuator rod disposed through said throat and having a contactor within said shell encircled by said displaceable contact free end portions whereby, radial deflection of said rod radially deflects said contactor to radially shift selected ones of said displaceable contacts into abutting engagement with said stationary contact disposed in the same said slot.
Claim 2
Dependent Claim
175 words
A multi-position switch including, a shell having a central throat in a front end, a support member within the opposite rear end of said shell, a plurality of stationary contacts disposed longitudinally within said shell, a plurality of displaceable contacts spaced adjacent and radially inwardly of said stationary contacts, said stationary and displaceable contacts having base portions fixedly disposed in said support member whereby the opposite free end portions of said radially adjacent contacts are normally maintained in a spaced apart manner, a guide member axially adjacent said support member and provided with a plurality of substantially radially extending slots throughout its length, portions of radially adjacent pairs of said stationary and displaceable contacts disposed within each one of said slots, an actuator rod disposed through said throat and having a contactor within said shell encircled by said displaceable contact free end portions whereby, radial deflection of said rod radially deflects said contactor to radially shift selected ones of said displaceable contacts into abutting engagement with said stationary contact disposed in the same said slot.
Claim 3
Dependent Claim
25 words
A switch according to claim 1 including, rigid means encircling the outer periphery of said guide member, and said stationary contacts abut said rigid means.
Claim 4
Dependent Claim
14 words
A switch according to claim 1 wherein, said displaceable contacts are of resilient wire.
Claim 5
Dependent Claim
14 words
A switch according to claim 1 wherein, all said contacts are of resilient wire.
Claim 6
Dependent Claim
20 words
A switch according to claim 1 wherein, said guide member includes a central web and said slots radiate outwardly therefrom.
Claim 7
Dependent Claim
16 words
A switch according to claim 1 wherein, said guide member and contactor are of dielectric composition.
Claim 8
Dependent Claim
51 words
A switch according to claim 1 wherein, said shell and guide member are cylindrical in cross-section, a guide sleeve intermediate said shell and guide member, said guide sleeve having an end wall partially restricting said throat and provided with a lobed opening defining the limits of said deflection of said rod.
Claim 9
Dependent Claim
36 words
A switch according to claim 1 including, spring means mounting the rear end portion of said actuator rod contactor to said support member, and said spring means normally maintaining said rod centrally disposed relative said throat.
Claim 10
Dependent Claim
38 words
A switch according to claim 1 including, a plug assembly attached to said shell rear end, said assembly including a base juxtaposed said contact base portions and a plurality of plugs axially extending from said plug assembly base.
Claim 11
Dependent Claim
18 words
A switch according to claim 1 wherein, said contactor includes a cylindrical periphery tapered toward said support member.
Claim 12
Dependent Claim
38 words
A switch according to claim 1 wherein, said stationary and displaceable contacts are adjacently disposed in pairs whereby, when said rod is deflected, two said displaceable contacts are simultaneously radially deflected into engagement with two said stationary contacts.
Claim 13
Dependent Claim
25 words
A switch according to claim 7 including, orientation means between said guide sleeve and both said support member and shell to insure angular alignment therebetween.
