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