Security power interrupt

An interrupt system which is operative to interrupt the transmission of power from a power supply to an electrical load, comprising:

• a controller, wherein said controller is operative to selectively supply or interrupt power to the load,
• a code-providing device detachably operatively connected with the controller, wherein said code-providing device is operable to provide an authorization code to said controller when operatively connected thereto, and wherein said controller is operative to supply power to the load responsive to the code-providing device providing said authorization code to the controller, and
• wherein the controller is operative to monitor the operative connection with said code-providing device, and wherein said controller is operative to interrupt power to the load responsive to said code-providing device being operatively disconnected from said controller.

An interrupt device for interrupting power to an electrical load connected to an electrical power supply, comprising

• a controller for switching the interrupt device between a mode in which power is supplied to the load, and a mode in which power to the load is interrupted, and
• an enabling device detachably coupled to the controller for providing an authorization code to the controller,
• wherein the controller monitors the enabling device and switches the interrupt device to the mode in which power to the load is interrupted in response to detachment of the enabling device.

An interrupt device for interrupting power to an electrical load connected to an electrical power supply, comprising

• a controller for selectively supplying or interrupting power to the load, and
• a code providing device wherein said code providing device provides an authorization code to the controller, for switching the interrupt device to a first mode in which power is supplied to the load responsive to an authorization code, wherein the code providing device is detachably coupled to the interrupt device,
• wherein the controller monitors the code providing device to determine when the code providing device has been detached from the interrupt device and switches the interrupt device to a second mode in which power to the load is interrupted responsive to detachment of the code providing device.
