5 meter long remote switch , originally made to be used with 35mm Film and Cine cameras , it can , because of it`s generic Jack Plug connection be used with other devices including winders ( providing they accept jack plug remotes of course ) . Not branded but it looks identical to the Kaiser models and is made in Germany so .... It cannot be used with DSLRs . In working order . I have tested it with a Jessops and a Minolta Power Winder and it works . Free UK P&P .
