wire diagram switch for bms JK-PB2A16S15P

[herrfreak]

Hi all
I am new here, and hope this question is in the right place. And from the netherlands, so englisch is not that good
I am buidling my first LiFePo4 battery pack 8S1P, after playing around with lithium ion.
During the build, the BMS+frame dropped with the switch already in the frame. All four wires broke clean of the switch.

I measured the switch, normal open, on the 2 connectors the widedest from each other
the other 2 seems to be not connected.

I did some searching on this forum and found this

esphome-jk-bms/docs/display-port.md at main · syssi/esphome-jk-bms

ESPHome component to monitor and control a Jikong Battery Management System (JK-BMS) via UART-TTL or BLE - syssi/esphome-jk-bms

github.com

If this is the same connector as on the github page, then i have to use the red(pin1) and black (pin2)
Seems like yellow(pin3) and green(pin6) are power supply (for the display)

I don't want to foobar my BMS
Question is, is there a diagram for this 4 wire switch?
Or are these switches (and displays) the same for these different BMS's , where mine is JK-PB2A16S15P and on github is JK-B2A24S15P?

Thanks for any help

Freek

Hi
I'm dutch my friend and am still puzzling what the connections are, but I make progress. here is a diagram from what I know till so far.
Let me know if you want to investigate this further with me because I can use some consultation (Ruggespraak).
Anyone that can add or correct me on this diagram, let me know,
Groeten
