Abstract
Abstract Time switch is arranged on a plug-in unit for a system housing containing various side-by-side unit components. The time switch includes a rotatable timing disk disposed for rotation about a lateral axis longitudinal of the housing and having a circumferential portion exposed exterior of a front plate of the plug-in unit. The disk is circumferentially formed with time range scale markings and has adjustable switch riders attached along the circumference for selectively triggering control switch as the disk rotates.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
149 words
Time switch apparatus for use in a system housing in the form of a module unit being transversely removable from said housing and having a front plate for facing flush with the front of said housing, comprising a rotatable timing disk adapted for rotation in said module unit about an axis longitudinal of said housing and having time scale markings extending circumferentially about said disk said front plate having an opening through which a portion of the circumference of said disk protrudes exterior of said housing front, adjustably positionable cam riders selectively mounted along the circumference of said disk, control switch means on said module unit for being triggered by said cam riders during rotation of said disk, and mounting means for enabling transverse movement of said disk module unit away from said housing to permit adjustment of cam rider positions on said timing disk in said module unit.
Claim 2
Dependent Claim
149 words
Time switch apparatus for use in a system housing in the form of a module unit being transversely removable from said housing and having a front plate for facing flush with the front of said housing, comprising a rotatable timing disk adapted for rotation in said module unit about an axis longitudinal of said housing and having time scale markings extending circumferentially about said disk said front plate having an opening through which a portion of the circumference of said disk protrudes exterior of said housing front, adjustably positionable cam riders selectively mounted along the circumference of said disk, control switch means on said module unit for being triggered by said cam riders during rotation of said disk, and mounting means for enabling transverse movement of said disk module unit away from said housing to permit adjustment of cam rider positions on said timing disk in said module unit.
Claim 3
Dependent Claim
21 words
The time switch apparatus of claim 1, wherein said time scale markings extend about the circumferential edge surface of said disk.
Claim 4
Dependent Claim
32 words
The time switch apparatus of claim 1, wherein said mounting means includes transverse track portions in said housing and a support plate on said module unit slidably received in said track portions.
Claim 5
Dependent Claim
44 words
The time switch apparatus of claim 3, wherein said control switch means includes electrical connector means for mating with power supply means in said housing, said electrical connector means disconnecting from said power supply means when said timing disk is withdrawn from said housing.
Claim 6
Dependent Claim
27 words
The time switch apparatus of claim 1, wherein said timing disk and control switch means are mounted together as a further module portion in said module unit.
Claim 7
Dependent Claim
44 words
The time switch apparatus of claim 5, wherein said control switch means includes electrical connector means for mating with power supply means in said housing, said electrical connector means disconnecting from said power supply means when said timing disk is withdrawn from said housing.
Claim 8
Dependent Claim
145 words
Time switch apparatus for use in a system housing in the form of a module unit being transversely removable from said housing and having a front plate for facing flush with the front of said housing, comprising a rotatable timing disk adapted for rotation on said module unit about an axis longitudinal of said housing and having time scale markings extending circumferentially about said disk, adjustably positionable cam riders selectively mounted along the circumference of said disk, control switch means on said module unit for being triggered by said cam riders during rotation of said disk, and mounting means for enabling transverse movement of said disk away from said housing to permit programming of said timing disk including extendible hinged bracket means disposed on said module unit for enabling transverse movement of said timing disk relative to said module unit and said control switch means.
Claim 9
Dependent Claim
145 words
Time switch apparatus for use in a system housing in the form of a module unit being transversely removable from said housing and having a front plate for facing flush with the front of said housing, comprising a rotatable timing disk adapted for rotation on said module unit about an axis longitudinal of said housing and having time scale markings extending circumferentially about said disk, adjustably positionable cam riders selectively mounted along the circumference of said disk, control switch means on said module unit for being triggered by said cam riders during rotation of said disk, and mounting means for enabling transverse movement of said disk away from said housing to permit programming of said timing disk including extendible hinged bracket means disposed on said module unit for enabling transverse movement of said timing disk relative to said module unit and said control switch means.
Claim 10
Dependent Claim
30 words
