Abstract

Abstract An inexpensive mechanical interlock for two switches that are mounted on a common support plate. The interlock consists of a single member which is mounted in a space between the two switches when the switches are mounted adjacent to each other on the support plate. The member has a pair of bearing portions received in recesses in the adjacent walls of the switches and a pair of actuating portions that are engaged by inclined surfaces on portions of the movable contact carriers of the two switches to prevent a concomitant operation of the switches to a circuit closing position.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 253 words
An assembly comprising: a pair of switches positioned sideby-side in spaced relation on a support plate with each of the switches including: an insulating housing having a pair of spaced sidewalls, a bottom wall extending between the sidewalls, a contact carrier movable between two positions in a cavity in the housing between the sidewalls along a plane that extends normal to the two sidewalls and the bottom wall; said assembly also comprising means including cooperating recesses and projections in the bottom walls of both switches and the support plate for locating and mounting the switches adjacent to each other on the support plate so the planes of movement of the contact carriers in the respective two switches extend in a common plane and the switches have spaced and parallel adjacent sidewalls; a bearing recess in the adjacent sidewall of each switch located adjacent the support plate and centered in the common plane, a window in the adjacent sidewall of each switch centered in the common plane and exposing a portion of the movable contact carrier to the space between the switches, a surface located on the exposed portion on each contact carrier disposed so that the surfaces on the adjacent switches are on opposite sides of the common plane and are inclined to face the support plate so that the portion of the surface that is most proximate the support plate is most remote from the common plane and a mechanical interlocking member consisting of a unitary member disposed between the adjacent switches.
Claim 2
Dependent Claim 253 words
An assembly comprising: a pair of switches positioned sideby-side in spaced relation on a support plate with each of the switches including: an insulating housing having a pair of spaced sidewalls, a bottom wall extending between the sidewalls, a contact carrier movable between two positions in a cavity in the housing between the sidewalls along a plane that extends normal to the two sidewalls and the bottom wall; said assembly also comprising means including cooperating recesses and projections in the bottom walls of both switches and the support plate for locating and mounting the switches adjacent to each other on the support plate so the planes of movement of the contact carriers in the respective two switches extend in a common plane and the switches have spaced and parallel adjacent sidewalls; a bearing recess in the adjacent sidewall of each switch located adjacent the support plate and centered in the common plane, a window in the adjacent sidewall of each switch centered in the common plane and exposing a portion of the movable contact carrier to the space between the switches, a surface located on the exposed portion on each contact carrier disposed so that the surfaces on the adjacent switches are on opposite sides of the common plane and are inclined to face the support plate so that the portion of the surface that is most proximate the support plate is most remote from the common plane and a mechanical interlocking member consisting of a unitary member disposed between the adjacent switches.
Claim 3
Dependent Claim 19 words
The assembly as recited in claim 1 wherein said holding means also comprising a portion of the support plate.
Claim 4
Dependent Claim 78 words
The assembly as recited in claim 2 wherein the unitary member is moved in one direction of rotation in response to the movement of the contact carrier of one of the two switches from a first to a second of said two positions and in a direction opposite the said one direction in response to the movement of the contact carrier of the second of the two switches from a first to a second of said two positions.
Claim 5
Dependent Claim 38 words
The assembly as recited in claim 2 wherein the interlocking member includes a portion that is engageable with portions of the adjacent sidewalls of the switches that surround the recesses for positioning the unitary member between the switches.
Claim 6
Dependent Claim 34 words
The assembly as recited in claim 4 wherein each of the recesses includes a portion having a hemispherical shape and the bEaring portions have a cylindrical shape and are journaled in the hemispherical portions.
Claim 7
Dependent Claim 19 words
The assembly as recited in claim 5 wherein the actuating portion of the interlocking member has a cylindrical shape.
