Abstract
Abstract A control switch for the input of a signal into a fire direction computer to select the ammunition for weapons from which a plurality of types of ammunition can be selectively fired. The control switch includes a plurality of switches each corresponding to one type of ammunition. A plurality of flip-flops, each corresponding to one switch, each have a set input connected to the associated switch and is settable thereby and each has at least one reset input connected to the remaining switches and is resettable by any one thereof, whereby only one flip-flop is set at a given time corresponding to the selected ammunition resulting in the output thereof providing the only input signal to the fire direction computer.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
128 words
A control switch for applying an input signal to a fire direction computer to indicate the selection of one of a plurality of types of ammunition which can be selectively fired, the control switch comprising: a plurality of actuatable switches each corresponding to one type of ammunition; and a plurality of flip-flops each corresponding to one switch and each having a setting input connected to the associated switch and settable in response to the actuation thereof and each having at least one resetting input connected to the remaining switches and resettable in response to the actuation of any one thereof; whereby only one flip-flop is set at a given time and only one flip-flop output applies an input signal to the fire direction computer indicating the desired ammunition.
Claim 2
Dependent Claim
128 words
A control switch for applying an input signal to a fire direction computer to indicate the selection of one of a plurality of types of ammunition which can be selectively fired, the control switch comprising: a plurality of actuatable switches each corresponding to one type of ammunition; and a plurality of flip-flops each corresponding to one switch and each having a setting input connected to the associated switch and settable in response to the actuation thereof and each having at least one resetting input connected to the remaining switches and resettable in response to the actuation of any one thereof; whereby only one flip-flop is set at a given time and only one flip-flop output applies an input signal to the fire direction computer indicating the desired ammunition.
Claim 3
Dependent Claim
48 words
A control switch according to claim 1, further comprising means connected to the output of each flip-flop and responsive to a blocking signal from the fire direction computer for disenabling the output from the set flip-flop for the duration of the blocking signal without resetting the set flip-flop.
Claim 4
Dependent Claim
53 words
A control switch according to claim 2, wherein said means for disenabling comprises a plurality of AND-NOT gates each corresponding to one flip-flop and each having a non-inverting input connected to the ouput of the corresponding flip-flop and each having an inverting input receptive of the blocking signal from the fire direction computer.
Claim 5
Dependent Claim
35 words
A control switch according to claim 3, further comprising a pulsing circuit responsive to the energizing of the control switch for initializing the control switch to set a given flip-flop and reset the remaining flip-flops.
Claim 6
Dependent Claim
18 words
A control switch according to claim 4 wherein each of the plurality of switches conprises a pushbutton switch.
Claim 7
Dependent Claim
28 words
A control switch according to claim 5, further comprising a plurality in indicator lamps each connected to the output of one flip-flop to indicate when same is set.
