Abstract

The invention provides a charge transfer type touch button and a control circuit thereof, which relate to the technical field of elevator buttons. A button plate (2) is arranged on the bottom of the inner side of a button shell (1), an inner die (3) is spliced with the button shell (1), and the upper edge of the inner die (3) is matched with the plane of the top end of the button shell (1). A first PCB (Printed Circuit Board) (4) is arranged in the inner die (3), a second PCB (5) is fixed on the button shell (1) and the inner die (3) through screws (6), and a locking nut (7) is screwed with the button shell (1). The structure is scientific and reasonable and does not have mechanical stroke. Due to the adoption of a capacity sensing technology, operation can be carried out with gloves on the hands. The invention has high sensitivity and high reliability, and error action can be effectively avoided.

Description

Technical field: [0001] The invention relates to the technical field of elevator buttons, in particular to a charge transfer type touch button and a circuit thereof. Background technique: [0002] With the continuous improvement of the level of modern buildings, high-rise and super high-rise buildings will dominate the building complex. In these large-scale buildings, many elevators need to be installed to meet the needs of people's work, and the elevator is a quick and convenient humanized device for transporting people or goods upstairs and downstairs. The elevator control system is a comprehensive and complex system integrating electromechanical, involving engineering fields such as machinery, electricity and automatic control. [0003] At present, the scale of intelligent buildings is constantly expanding. Therefore, it is of great practical significance to improve the operating efficiency of elevators in buildings and the quality of humanized services. The traditional...
