Abstract

Abstract: For common household electrical appliances with spring or thin film touch buttons, because the working voltage of the buttons are not high, they are easy to be ignored in the product structure design and safety test, and fail in the test of electric strength, material, creepage distances and clearances and so on. Through the summarizing of actual cases, analyzing the reasons for fail and suggestions for improvement measures that can be adopted, so as to provide effective reference for product designers and safety test engineers.

Key words: Spring touch button, Thin film touch button, Capacitive induction coil, Live parts
