It depends on how the distributor is set up. If it is set up for an armored cable then you can use one with just the wire protruding from the end in the dash to connect to a standard switch. If the distributor is converted with a modern points & condenser plate in it. A plain wire can be used between the distributor and the dash. They make a switch that appears to be a pop out that can be used in lieu of the original Electrolock. Reproduction pop outs were available for a long time but they weren't as reliable as the original Electrolock units. Rebuilt originals are sometimes available on flea-pay but they will be expensive. I imagine everything is expensive in your location though.
