A control device for a sanitary device for a toilet assembly which reduces the size of a control case and increases the damp-proof characteristics of an electrically conductive member by restricting the invasion of water, urine, and moisture content. Each bushing assembly has an elastomeric bushing disposed around the stabilizer bar and an outer metal member disposed around the elastomeric bushing. The DC offset cancellation circuit uses a changeover circuit to change a state of a low-pass filter with a hold function in synchronization with an inversion electrical pulse signal, and performs a negative feedback of a filtered signal which is generated by subjecting third differential signals to low-pass filtration or a hold filtered signal which is a filtered signal held during changeover. In various aspects, the accessory token is communicatively coupled to the telecommunications device, which enables the telecommunications device to obtain the identifier.
