Here 2 UAV CAN Safety Switch

In case someone else stumbles across this in the future. See this thread. The safety switch on the Here2 is not set up to be used as a UAVCAN safety switch. It’s the closest thing we have to a physical on off switch.

Now to respond to @philip above me.
First…So long as arming procedures are properly followed (prearm checks and rudder/GCS arm) the vehicle will not turn on any moving parts when the safety switch is pressed.

Second…If the safety switch fails in an open state, the vehicle remains in a state of no output. If the switch fails in a closed state, the vehicle is still not armed (assuming proper arming procedures are followed).

Third…Yeah that one is still not a great way of dealing with the issue. Not really a great place to put a switch, but it at least is easier to jump away from pressing a button than it is from plugging in a battery.

Forth… The bitmask parameter BRD_SAFETYOPTION allows for the safety switch to only be used while the vehicle is disarmed. Your following sentence after this point states this as well.

A simple yes or no at the top would have worked too.
