Bathing unit controller and connector system therefore

A controller (30) suitable for use in controlling components (35) in a bathing unit is provided. The controller includes a plurality of connectors (34) adapted for providing electrical power to respective bathing unit components. Each connector includes a set of contact elements (36) arranged in a common configuration. A first subset of the set of contact elements is adapted for generating a power signal characterized by a first current-voltage combination and a second subset of the set of contact elements is adapted for generating a power signal characterized by second current-voltage combination. In accordance with another aspect, a keying system is providing including a key member (38) for engaging a connector and a complementary key member (39) for engaging a electrical plug. The keying system enables the electrical plug and the connector to establish an electrical connection when the key member and then complementary key member match.
