Standby switch for SFR-1

The standby switch is plugged into connector X9 of sound speed controller 

When the standby switch is closed, the BEC voltage of the SFR-1 is switched off and the sound speed controller goes to "standby".
The current consumption of the module then drops to a current of only approx. 1 mA.
This allows the model to stay on standby for several hours without noticeably draining the battery.
However, if the model is not to be used for several days, the battery should be disconnected completely.

The standby switch comes with a soldered cable. The cable length is approx. 25 cm.
