The top mounted fuse holder and fuse have been removed. There is no longer any need to keep spare fuses around and worry about making changes in the field. An internal auto-resetting circuit breaker rated at 6 amps has replaced the fuse.

The master switch has been recessed into the box, thus eliminating the guard collar and reducing the overall length of the box. Also, the switch is less likely to be accidentally switched.

Changing output #1 from switched to unswitched is now much easier. The previous soldered jumpers have been replaced with computer type jumpers that do not require soldering. CLICK For LARGE INTERNAL IMAGE.

The box is easier to open for moving jumpers. Simply remove two Philips head screws and open the box.

Two sides are now tapped with threaded holes for the belt clip allowing it to be positioned on either the back or bottom of the box.

The box is now smaller. By removing the external fuse and recessing the switch, the overall dimensions are now shorter and narrower than before.
