Claim 10:
11. An intermediate signal transmission unit configured to provide wireless communication between a camera and at least one remote flash device, the unit comprising:
a housing comprising a first housing part and a second housing part which are connected,
a connector configured to connect the housing to a camera, said connector being arranged on the second housing part, and
signal transmission components accommodated in the housing and including a signal transmitter configured to send control signals to the at least one remote flash device,
wherein:

the first housing part is displaceable in relation to the second housing part,
the first housing part comprises at least one actuator configured to control at least one switch, said switch being part of the signal transmission components and located in the second housing part, and

wherein:
the connector of the housing is configured to enable bi-directional exchange of signals between the signal transmission components of the intermediate signal transmission unit and the camera, and
the signal transmission components comprise at least one switch configured to control the communication between the camera and the at least one remote flash device by controlling operation modes of the intermediate signal transmission unit, and which switch is configured to be controlled by the actuator when the first housing part is displaced in relation to the second housing part such that when the actuator is in a first position the switch is in a first state wherein the intermediate signal transmission unit functions in a first operation mode, and when the actuator is in a second position the switch is in a second state wherein the intermediate signal transmission unit functions in a second operation mode.
