Abstract
Abstract A reel which is connected with one end of an electric cable and is provided with an electric switch which can be closed by hand to establish an electric connection between the conductors in the cable. The cable can be convoluted on or paid out by the core of the reel and its free end is provided with a plug which can be inserted into the socket of a camera or projector to complete a circuit in such apparatus in response to closing or opening of the switch. The reel is further formed with a socket which can receive the plug on the cable of a second reel and is connected in parallel with the switch so that an operator can complete an electric circuit which is connected with the plug of the first cable by closing or opening the switch of the second reel.
