Abstract
Abstract A line cord switch, the casing of which is subdivided by an insulating panel into two compartments. The line cord is in one compartment and the active switch elements including the actuating element and electrical contact elements are in the other compartment. The switch actuating element is of triangular shape and is rockably mounted within the switch compartment. Two of the apices of the switch actuating element are arranged to alternately project from opposite sides of the casing corresponding to either off or on position of the switch.

Claim 1
Independent Claim
285 words
An electric switch for a twin wire line cord, said switch comprising: a. a first hollow housing having one open side, b. a second hollow housing having one open side, c. said housings being in opposed registered abutment with their open sides facing each other so as to jointly constitute a casing, d. a panel of insulating material physically distinct from said housings, said panel being disposed between said housings and located within the casing so as to form in conjunction with the hollow of each housing a different internal compartment, e. means within one housing providing two channels for receiving a twin wire line cord, i. one of said channels being continuous to accommodate one unbroken wire of the twin wire line cord, ii. the other of said channels being discontinuous, iii. the other wire of said twin wire line cord having a cut therein, iv. the other channel accommodating the other wire with the cut ends thereof in different segments of the discontinuous other channel, f. movable and stationary switch members for opening and closing the circuit between cut ends of the other wire of the twin wire line cord, g. said members being located in and enclosed by the compartment of the other housing, h. means within said other housing to hold said members in operable position, i. said insulating pannel having two openings therein each adjacent a different segment of the discontinuous channel, j. each of said members having a piercing point extending through a different one of said openings to be embedded in a different one of the cut ends of the other wire to electrically connect said cut ends when the movable and stationary switch members are in engagement.

An electric switch for a twin wire line cord, said switch comprising: a. a first hollow housing having one open side, b. a second hollow housing having one open side, c. said housings being in opposed registered abutment with their open sides facing each other so as to jointly constitute a casing, d. a panel of insulating material physically distinct from said housings, said panel being disposed between said housings and located within the casing so as to form in conjunction with the hollow of each housing a different internal compartment, e. means within one housing providing two channels for receiving a twin wire line cord, i. one of said channels being continuous to accommodate one unbroken wire of the twin wire line cord, ii. the other of said channels being discontinuous, iii. the other wire of said twin wire line cord having a cut therein, iv. the other channel accommodating the other wire with the cut ends thereof in different segments of the discontinuous other channel, f. movable and stationary switch members for opening and closing the circuit between cut ends of the other wire of the twin wire line cord, g. said members being located in and enclosed by the compartment of the other housing, h. means within said other housing to hold said members in operable position, i. said insulating pannel having two openings therein each adjacent a different segment of the discontinuous channel, j. each of said members having a piercing point extending through a different one of said openings to be embedded in a different one of the cut ends of the other wire to electrically connect said cut ends when the movable and stationary switch members are in engagement.
Claim 3
Dependent Claim
33 words
An electric switch in accordance with claim 1 wherein there is included manually manipulatable actuating means for selectively moving said movable switch member into and out of electrical engagement with the stationary member.
Claim 4
Dependent Claim
45 words
An electric switch in accordance with claim 1 wherein the panel includes two additional openings and wherein each switch member has an integral part thereof a tab, said tabs extending through the additional openings and engaging the panel to secure said members to said panel.
Claim 5
Dependent Claim
98 words
An electric switch in accordance with claim 2 wherein the actuating means constitutes an actuating member and mean for mounting the actuating member for oscillation between two positions in the other housing, said actuating member having two surfaces shaped and constructed to be selectively pressed by a finger of a user for operating the electrical switch, one of said surfaces being retracted into the other housing and the other of said surfaces protruding from said other housing in a first position of the actuating member and such positions being reversed in a second position of the actuating member.
Claim 6
Dependent Claim
100 words
An electric switch in accordance with claim 2 wherein the movable switch member has a resilient portion normally biasing a contact associated therewith into a position spaced from a contact associated with the stationary switch member, and wherein the actuating member is electrically non-conductive and movable between two positions in one of which it flexes the contact of the movable switch member into electrical and physical engagement with the contact of the stationary switch member and in the other of which it permIts the movable switch member to move its contact away from the contact of the stationary switch member.
Claim 7
Dependent Claim
40 words
An electric switch in accordance with claim 4 wherein the other hollow housing is formed with openings to permit one or the other of said surfaces to extend beyond said other housing depending upon the position of the actuating member.
Claim 8
Dependent Claim
90 words
An electric switch in accordance with claim 6 wherein said actuating member is of a deltoid configuration having three apices, one of said apices protruding through one of said openings in one position of the actuating member and the other of said apices protruding through the other opening in the second position of said actuating member, said switch including resilient means responsive to the position of the third of said apices for selectively moving the movable switch member into and out of electrical physical engagement with the stationary switch member.
