Turnigy 5 amp (7.5 amp) UBEC

[Old School]

I have done similar mods to my Turnigy 180 esc,s where there is an on / off switch which is only a continuity wiring , so its just a matter of removing the switch and joining both black and red wires together. its a very cheap switch so in time it could fail in its connections.

The problem is that the Turnigy/Hifei/Hobbywing 7.5 amp ubec switch is the opposite logic to what a switch should be. On the Turnigy when the switch is removed then there must be no continuity between the switch wires or there will be no output. If the wires are joined then there is no output, unlike say the 180 amp ESC switch.
