I have been using a 3.5 mm switching Audio Jack in order to charge/switch-on and off my RC-Glider model. For this I connected the battery of my RC-glider to the one-part of the audio jack and the electronics to the other side. The audio jack I use seems to be a SJ1-3515 (although, I am not sure as this switch was delivered with the model). Here are the schematics:
However I noticed that whenever I plug-in or plug-out a cable, ground is shortly connected to either of the two other pins, which then of course shorts-out my battery! This led to high-current and some very hot wires which desoldered my connections to the switch. Obviously I do not want to short my battery every time I plug-in or plug-out the charger or the on-off insert.
Therefore my question(s):
- Is this a normal behavior for a switching 3.5mm Jack?
- Can someone tell me if non-shorting-out 3.5mm Jack connectors exist, and how to find those? Or am I just plainly using the wrong tool for the job?
Thanks in advance!
Edit: Per demand I included a (badly drawn) schematic. Edit2: Generalized the question such that I ask for the class of non-shorting products instead of a specific product.
