The adapter's wiring as well as the sockets dimensions establish the useful applications of these adapters. These adapters are made of 3 sub-assemblies. They assemble via connectors making the adapter modular. This way the sub-assemblies can be replaced easily. When disassembling the adapter, take care not to bend the pins. When reassembling the adapter, note the pin 1 indicators to align the parts correctly.
