I am using a 3DR Pixhawk, PX4 on a DJI F450 frame. The status LED on the safety switch is not illuminating, but it seems that the switch is functioning (for example, when running the ESC calibration procedure, the switch enables power to the motors). The switch is brand new. I purchased it from JDrones, the only supplier I could find in the world making this switch. I have contacted JDrones to inquire how to test the switch, and we'll see what that brings. However, by searching this forum, I also found that several others have recently experienced safety switches that have been mis-wired. The wiring diagrams however appear to be related to a different controller, with a J17 connector. My pixhawk has a DF13-3P connector.
Attached is a picture of how the switch that I received is wired. Could someone take a look and tell me whether this wiring is correct or not? Thanks much.
