I’m never one to stop at “simple,” but often find myself overthinking things.
MY QUEST: I have placed a simple keyed switch along the ground wire to the transmission shift interlock. I want to be able to leave my car on while I run out for brief moments and not worry about someone seeing opportunity. This simple implementation works, as the transmission will not budge when the switch opens the ground line. However, the key is cumbersome to slide into the mechanism, and so I have ordered an RFID access system that offers a relay that can open a circuit on a timer, momentarily, or “flip flop.”
My ultimate vision is to have a simple momentary button that I can press which will then break the circuit to the shift interlock until the RFID access system senses a fob and allows the circuit to become whole again. It seems much easier to press a button and hop out of the car rather than fumble for the key and twist it and then remove it, etc.
MY QUESTION: How would I go about wiring a circuit up such as this? Assuming I don’t use the RFID access system and instead decide to have one momentary switch when pressed then requires another switch (hidden) to be pressed or toggled to close the circuit?
(In essence, if someone were to see me press one button and then they themselves decide to push the same button, they would achieve nothing unless they find the second switch - which when pressed would then re-activate the shift interlock and the first button.)
