AC power at 15 amps and a radio frequency signal are transmit- ted in a coaxial cable to a telecommunications amplifier. The AC signal is separated from the RF signal by a radio frequency module. The AC signal is converted to a regulated DC voltage for supplying power to condition and amplify the radio frequency signal transmitted from the amplifier. A power supply module in the amplifier is connected through a bank of fuses and a power switch to the RF module. A cover plate overlies the fuses and the electrical connection between the power supply module and the RF module. The power switch includes a toggle lever movable between power on and power off positions to transmit power between the modules. To prevent exposure of operating personnel and the electrical equipment to the hazards of high voltage and electric shock, the toggle switch obstructs movement of the cover plate exposing the fuses in a power on position. The toggle switch must be pivoted to the power off position before the cover plate can be moved to allow access to the fuses and the line voltage test points. Retaining screws and hold-down screws lock the cover plate in the power on position.
