Hi Guys, Im totally new here and I'm not even sure if this is the right forum, but I think there are a lot of people here who know all about electronics. Ok so I bought an electric scooter. It has an on/off switch but no kind of security. So if I hook it up to a pole and leave, people can still turn it on. That's why I want a remote on/off switch which would allow me to disable the builtin switch. The top of the steering tube is quite easily removed which expose the on/off switch wiring. this is the switch I was thinking about: remote switch they say the receiver works on 10-14V.(DC) Now the scooter has a huge combination of batteries in it (3.6V ICR18650-M26 2600mAh Max 10A) and the specs say it has a battery charge limit of 42V. Now I don't think all that juice will flow through the builtin switch(will check with a multimeter soon. But what do I need if the voltage is lower or higher than the recommended 10-14V? also the standby current is < 5MA, am I correct this is practically nothing? so question 1: what to do when voltage doesn't match recommended receiver voltage? questions 2: is a RF signal able to go through 1 or 2mm aluminum? question 3: Am I correct that I won't even notice the standby current usage after a few hours? question 4: if nobody tells me I'm crazy or stupid to even try this can someone guide me through which ports on the receiver I need to connect what. (yes I know where + and - goes but I don't really get the NC/COM/NO.
