A neon sign includes a transformer module and a receptacle attached to the neon sign for receiving the transformer module. The transformer module is configured to mate with the receptacle as the transformer module is plugged into the receptacle in order to connect the transformer module to the neon sign. The transformer module includes a high voltage transformer for transforming a primary input voltage into a secondary high voltage output. The transformer module also includes secondary contacts for connecting the secondary high voltage output of the transformer module to the neon sign when the transformer module is plugged into the receptacle. The receptacle also includes secondary contacts configured to mate with the secondary contacts of the transformer module as the transformer module is plugged into the receptacle thereby electrically connecting the secondary high voltage output of the high voltage transformer to the neon sign. The neon sign further includes a deactivating arrangement for deactivating at least the secondary contacts of the transformer module as a result of the transformer module being unplugged from the receptacle.
