Abstract
A keyboard module includes a pressing layer, a switch circuit board, a base plate and plural glue dots. The pressing layer includes plural key parts. The switch circuit board includes plural first wiring patterns, plural second wiring patterns and plural spacing dots. The plural glue dots are disposed on a lower wiring plate of the switch circuit board. The plural glue dots and the plural spacing dots are staggered. Due to the plural glue dot, the non-bonding zones of the lower wiring plate without the glue dots are bendable. When the key part is pressed, the lower wiring plate corresponding to the pressed key part is bent. Consequently, the first wiring pattern is inserted into the region between the corresponding spacing dots and contacted with the corresponding second wiring pattern.

A keyboard module, comprising:
- a pressing layer comprising plural key parts, wherein the plural key parts are exposed to a top surface of the keyboard module;
- a switch circuit board disposed under the pressing layer, wherein when the switch circuit board is triggered by one of the plural key parts, a corresponding key signal is generated, wherein the switch circuit board comprises plural key intersections and plural spacing dots;
- a base plate connected with the switch circuit board, wherein the pressing layer and the switch circuit board are supported on the base plate;
- and
- plural glue dots arranged between the base plate and the switch circuit board, wherein the base plate and the switch circuit board are combined together through the plural glue dots, wherein the plural glue dots and the plural spacing dots are staggered.
