This mechanical switch is used to operate the buttons in the ACT safety switches and battery backers (DPS & PS systems) for the ON/OFF function from the outside if these are installed inaccessibly in the fuselage. This does not switch the operating current. When the external switch is connected, the buttons on the soft or switch board are bridged, these are then no longer in operation.

NOTE: This switch is only suitable for use on the DPS & PS systems. It cannot be used as an ON/OFF receiver switch.
