Novel separate empty touch button of taking lamp

Technical Field

The utility model relates to the technical field of keys, in particular to a novel spaced touch type key with a lamp.

Background

An induction capacitor exists between any two conductive objects, one key, namely one bonding pad and a grounding end can form the induction capacitor, and the value of the induction capacitor is a fixed and unchangeable tiny value under the condition that the surrounding environment is unchanged. When a human finger approaches the touch key, an induction capacitor is formed between the human finger and the grounding terminal, and the total induction capacitance value is increased by the induction capacitor formed by the parallel connection bonding pad and the grounding terminal. The capacitive touch key IC outputs a determination signal that a certain key is pressed after detecting that the value of the induction capacitance of the certain key is changed.
