I disconnected this switch and tested with multimeter:
- it has 0.05 Ohm when not pressed
- it has about 2.7 kOhm when pressed, so this switch is OK
This led my suspicious to cable and bingo ! The one was broken near upper hinge mechanism (image below):
I am replacing the same micro switch (Left, shell 2)
I bought a brand new BMW micro switch online, and first tested it for continuity and the multimeter did not beep, pressed or not pressed.
So I thought maybe it was DOA. Then after seeing your post I tested for ohms and ohms changes when I pressed the button. Is there a pull up resistor in the switch? But my main question is the switch I got is good to go replace the one in the car.
I tested for ohms, and I am getting
- it has **0.05
kOhm** when not pressed (in your post you wrote **Ohm**, not **kOhm**)*************
- it has about 2.7 kOhm when pressed (I am getting similar to this)
...Note.. I am able to raise/close the convertible roof by unplugging pin 7 wire and putting a jump wire (pin receptacle contact attached) into that socket position 7 and a needle at the end of that jump wire going behind pin 10 copying the signal from the right microswitch.
