Abstract
Abstract A switching system is constructed using a plurality of modules. Each module controls the power to a separate load and includes a capacitor, a silicon controlled rectifier, and a switch. In each module the gate of each of the controlled rectifiers is connected, through a switch, to a common lead line which line is also connected to one side of the capacitor.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
240 words
A switching circuit to switch power from a power source having first and second terminals to a plurality of loads each having an input and an output terminal, said circuit consisting of at least two modules; the first module including a first line connected to the first terminal of the power source and to the input terminal of the first load; a second line; a third line connected to the second terminal of the power source, a resistor between said first and second lines; a capacitor connected between the second line and the output terminal of the first load; a controlled rectifier having an anode, cathode and a gate, the anode being connected to the output terminal of the first load and the cathode being connected to the third line; and a switch having two terminals and an operating means, one terminal of the switch being connected to the gate and its other terminal being connected to the second line; the second module including a capacitor connected between said second line and the output terminal of the second load; a controlled rectifier having an anode, cathode and a gate, the anode being connected to the output terminal of the second load and the cathode being connected to said third line; and a switch having two terminals and an operating means, one terminal of the switch being connected to the gate and its other terminal being connected to said second line.
Claim 2
Dependent Claim
240 words
A switching circuit to switch power from a power source having first and second terminals to a plurality of loads each having an input and an output terminal, said circuit consisting of at least two modules; the first module including a first line connected to the first terminal of the power source and to the input terminal of the first load; a second line; a third line connected to the second terminal of the power source, a resistor between said first and second lines; a capacitor connected between the second line and the output terminal of the first load; a controlled rectifier having an anode, cathode and a gate, the anode being connected to the output terminal of the first load and the cathode being connected to the third line; and a switch having two terminals and an operating means, one terminal of the switch being connected to the gate and its other terminal being connected to the second line; the second module including a capacitor connected between said second line and the output terminal of the second load; a controlled rectifier having an anode, cathode and a gate, the anode being connected to the output terminal of the second load and the cathode being connected to said third line; and a switch having two terminals and an operating means, one terminal of the switch being connected to the gate and its other terminal being connected to said second line.
Claim 3
Dependent Claim
93 words
A switching circuit as in claim 1 and also including a third module, the third module including a capacitor connected between said second line and the output terminal of the third load; a controlled rectifier having an anode, cathode and a gate, the anode being connected to the output terminal of the third load and the cathode being connected to said third line; and a switch having two terminals and an operating means, one terminal of the switch being connected to the gate and its other terminal being connected to said second line.
Claim 4
Dependent Claim
20 words
A switching circuit as in claim 1 wherein each of the switches is a normally open spring-loaded manually operated switch.
