Capacitive touch sensor assembly for use in a wet environment

摘要: A controller for use in a wet environment, such as pool or spa, includes sensor element that generates an electric field having active region. For the controller, at least one flexible layer is positioned to overlay and surround With this arrangement, pocket established between element. control circuit responsive capacitance provided. When deformed, changes output signal corresponds particular switch state connected device (e.g. pump heater). designed and/or calibrated maintain current response presence of water on near
