Indicator and control device for PC boards

Claim 2

An indicator and control device for PC boards and the like comprising: an elongated generally rectangular component mounting plate having a front surface, a rear surface and a longitudinal axis, said plate being provided with at least one elongated aperture lying parallel to and laterally offset from said longitudinal axis, and at least one other aperture; an elongated indicator means affixed to said rear surface so as to be viewable through said elongated aperture; a manually operable electrical component mounted within said other aperture; a pair of insulating standoff members disposed along said longitudinal axis and provided with slots for receiving an edge of a circuit board; means attaching said standoff members to the rear surface of said mounting plate, a first terminal board attached to one side of said standoff members and having biasing elements mounted thereon; a second terminal board attached to the opposite side of said standoff members; and means for electrically interconnecting said indicator means, said electrical component, the biasing elements of said first terminal board and said second board, whereby said indicator and control device may be attached to a PC board by lodging an edge thereof within the slots of said standoff members, and may be electrically connected thereto by wiring said second terminal board to the electrical circuits of said PC board.

Claim 3

An indicator and control device as recited in claim 1 wherein said second terminal board includes a plurality of contact pins extending therethrough and wherein the ends of said pins on one side are selectively connected to said indicator means, said electrical component and said biasing elements.

Claim 4

An indicator and control device as recited in claim 1 wherein said first terminal board has a plurality of terminal pins formed on one side and printed electrical circuits formed thereon for electrically connecting said biasing elements to said pins.

Claim 5

An indicator and control device as recited in claim 1 further comprising: an elongated, transparent view plate disposed against the rear surface of said mounting plate and covering said elongated aperture; a first mounting block disposed to engage a first end portion of said view plate; first means for attaching said first mounting block to the rear surface of said mounting plate; a second mounting block disposed to engage a second end portion of said view plate, and second means for attaching said second mounting block to the rear surface of said mounting plate, whereby said first and said second mounting blocks retain said view plate in position against the rear surface of said mounting plate and over said aperture.

Claim 6

An indicator and control device as recited in claim 4 wherein said first and said second mounting blocks are each provided with a slot receptive to respective end portions of said viewing plate.

Claim 7

An indicator and control device as recited in claim 1 wherein said standoff members are shaped like rectangular prisms and have opposing front and rear surfaces, whereby said front surfaces of said standoff members abut said rear surface of said mounting plate and said slots are formed inwardly from said rear surface of said standoff member.

Claim 8

An indicator and control device for mounting to an edge of PC boards and the like comprising: an elongated generally rectangular component mounting plate having a front surface, a rear surface and a longitudinal axis, said plate being provided with an indicator aperture and another aperture; an indicator means affixed to said mounting plate at said indicator aperture; a manually operable electrical component mounted within said other aperture; a pair of insulating standoff members disposed along said longitudinal axis and provided with slots for receiving an edge of the PC board to which said device is to be mounted; means attaching said standoff members to the rear surface of said mounting plate; a first terminal board attached to one side of said standoff members and having biasing elements mounted thereon; a second terminal board attached to the opposite side of said standoff members and having means forming electrical terminals; and means for electrically interconnecting said indicator means, said electrical component, the biasing elements of said first terminal board, and the terminals of said second board, whereby said indicator and control device may be attached to a PC board by lodging an edge thereof within the slots of said standoff members, and may be electrically connected thereto by wiring the terminals of said second terminal board to the electrical circuits of said PC board.

Claim 9

An indicator and control device for mounting to an edge of PC boards and the like comprising: an elongated generally rectangular component mounting plate having a front surface, a rear surface and a longitudinal axis, said plate being provided with an indicator aperture and another aperture; an indicator means affixed to said mounting plate at said indicator aperture; a manually operable electrical component mounted within said other aperture; a pair of insulating standoff members disposed along said longitudinal axis and provided with slots for receiving an edge of the PC board to which said device is to be mounted; means attaching said standoff members to the rear surface of said mounting plate; a first terminal board attached to one side of said standoff members and having biasing elements mounted thereon; a second terminal board attached to the opposite side of said standoff members and having means forming electrical terminals; and means for electrically interconnecting said indicator means, said electrical component, the biasing elements of said first terminal board, and the terminals of said second board, whereby said indicator and control device may be attached to a PC board by lodging an edge thereof within the slots of said standoff members, and may be electrically connected thereto by wiring the terminals of said second terminal board to the electrical circuits of said PC board.

Claim 10

An indicator and control device as recited in claim 7 wherein said second terminal board includes a plurality of contact pins extending therethrough to form said terminals and wherein the ends of selected ones of said pins on one side are respectively connected to said indicator means, said electrical component and said biasing elements.

Claim 11

An indicator and control device as recited in claim 7 wherein said first terminal board has a plurality of terminal pins formed on one side and printed electrical circuits formed thereon for electrically connecting said biasing elements to said pins.

Claim 12

An indicator and control device as recited in claim 7 wherein said indicator aperture is elongated and lies parallel to and laterally offset relative to said longitudinal axis, and said device further comprises: an elongated, transparent view plate disposed against the rear surface of said mounting plate and covering said indicator aperture; a first mounting block disposed to engage a first end portion of said view plate; first means for attaching said first mounting block to the rear surface of said mounting plate; a second mounting block disposed to engage a second end portion of said view plate; and second means for attaching said second mounting block to the rear surface of said mounting plate, whereby said first and said second mounting blocks retain said view plate in position against the rear surface of said mounting plate and over said indicator aperture.

Claim 13

An indicator and control device as recited in claim 10 wherein said first and said second mounting blocks are each provided with a slot receptive to respective end portions of said viewing plate.

Claim 14

An indicator and control device as recited in claim 7 wherein said standoff members are shaped like rectangular prisms and have opposing front and rear surfaces and wherein said front surfaces of said standoff members abut said rear surface of said mounting plate and said slots are formed inwardly from said rear surface of said standoff member.
