Self-contained apparatus/automatic door having a non-contact sensor switch assembly
A non-contact sensor switch assembly includes a switching transistor adapted for switching on/off the supply of a power supply to the control unit of an automatic handwash dispenser, automatic water tap or automatic door, a charge induction plate inducible by an approaching body part of a person, and a capacitive proximity sensor electrically coupled between the charge induction plate and the switching transistor for triggering the switching transistor to switch on the supply of the power supply to the control unit of the automatic handwash dispenser, automatic water tap or automatic door upon approach of a body part of a person.
