Abstract
Abstract The circuit for controlling the stopping of equipment comprises a switch with two contacts and with a pushbutton able to bring about the switching of the contacts into an open position and a closed position. The circuit comprises a supplementary member which functions like the pushbutton and is controlled by a relay in series with one of the contacts of the switch, this relay being responsive to a remote control device.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
103 words
A circuit for controlling the stopping of equipments, each individual equipment being connected to a power supply and being provided with a switch having at least one contact, said switch being associated with at least one pushbutton able to bring about the alternate switching of said contact into an open position and a closed position, wherein said circuit comprises a supplementary member for controlling the switch, said member being functionally equivalent to the pushbutton, said member being controlled by a relay in series with one of the contacts of the switch, said relay being responsive to remote control means for switching said switch.
Claim 2
Dependent Claim
103 words
A circuit for controlling the stopping of equipments, each individual equipment being connected to a power supply and being provided with a switch having at least one contact, said switch being associated with at least one pushbutton able to bring about the alternate switching of said contact into an open position and a closed position, wherein said circuit comprises a supplementary member for controlling the switch, said member being functionally equivalent to the pushbutton, said member being controlled by a relay in series with one of the contacts of the switch, said relay being responsive to remote control means for switching said switch.
Claim 3
Dependent Claim
26 words
A circuit according to claim 1, wherein the remote control means of the relay comprises a power supply independent of the supply network for the equipment.
Claim 4
Dependent Claim
28 words
