Touch spring refers to the special spring button specially used for capacitive and single-chip touch screen electrical appliances. Touch springs are also called touch sensing springs, button springs, and contact springs.

A robust capacitive sensing alternative to traditional mechanical switches. With retractable touch keys, the product can be controlled by touch keys without changing the shell mold, and the touch sensitivity is very good.

Metal Spring Inductors - Can be used as an alternative to solid state conductance sensors so that the PCB can be positioned away from the overlay and provide a reliable sensor connection under operating conditions with high vibration or extreme temperature changes. In addition, springs can provide other features such as backlighting, blending mechanical and capacitive buttons, and more.
