What is this switch and how to remove it
#46
No bridge
The contact strips on the bottom 2 are the same so it's a redundant feature in case one " lifts off " of contact , this increases the reliability
Your focus is pin 6 ( Green / Orange wire ) and 7 ( Red / Orange ) for the stater relay command ground path through the switch
So you have 6 soldier points for 6 pins on the top of the pic
The rotary pivot probably has 2 contact brushes to bring the total to 8 pins
Probably the best you can do with the pivot point brushes is an alcohol wash and not a solvent that may damage or warp the fine plastics in the pivot point , this is probably your fluid intrusion area and not the O - ring seal

Yes , I found by clamping them together over night the better
someone used Tywrasp and I use a battery jumper cable ( overkill )
Must put something over the battery post to not make contact
I was just at a salvage yard so there are fresh pickings on a X300 that just came in like a BPM or a rotary switch

The BPM is looking for all agreements / enables on the left side and then provides a command ground for the 2 relays for the interlock solenoids
Thinking on your last sentence in how this ties into the starter solenoid relay but the agreements / enables are a different set of devices in the starter solenoid circuit
So this raises the question of what goes on inside the box which you may not ihave information about clouding up what information you do have
In the end the BPM must provide a command ground for the starter solenoid relay so a test light bulb that you can see from the cabin by yourself may be helpful , this test bulb at the starter solenoid relay will be confirming your rotary position switch path is good or not as 1 of 2 possibilities , either the BPM is not providing the command ground, or the rotary position switch is not enabling a ground path
Have you swapped this starter solenoid relay as it may be marginaly failed in a manor and not totally ?
I think you changed the starter but someone recently did find a starter assembly connection loose
The question is if the BPM is being powered by the fuse in the trunk ? This involves a connector to learn it,'s precaution about before tinkering with the connector
