Somehow I lost the switch piece that goes between the PCB switch and the shell for user to use. Without it, it is hard to turn the unit on or off as the switch itself is rather deep inside through a small hole.
I suspect one of my cat has it, she often steals LEGO pieces and other small plastic parts. The green switch piece would look like toy to her.
eBay is a little dry on spare parts, the cheapest unit is over $200 -_- So anyone got a spare switch for TE or GT? Buying one + shipping in USA.
