I'm pretty new to practical electronics and am a bit jumpy about soldering, connecting stuff up etc after seeing how a 9V battery can cause an LED to explode without a limiting resistor.
I just soldered this switch to a battery holder and put a 9V battery in and the switch lit up without me connecting it to anything else. does it have internal resistance and is it safe?
