Abstract
A keyswitch device includes a bottom plate, a membrane circuit board, a keyswitch assembly, and at least one spacer structure. The membrane circuit board is located over the bottom plate and has a trigger zone. The membrane circuit board is configured to generate a trigger signal when the trigger zone is pressed. The keyswitch assembly is disposed over the membrane circuit board and configured to press the trigger zone. The spacer structure is disposed between the bottom plate and the membrane circuit board and substantially aligned with the peripheral edge of the trigger zone. The spacer structure is configured to separate the bottom plate and the membrane circuit board by a distance.

A keyswitch device, comprising:
- a bottom plate;
- a membrane circuit board located over the bottom plate and having a trigger zone, wherein the membrane circuit board is configured to generate a trigger signal when the trigger zone is pressed;
- a keyswitch assembly disposed over the membrane circuit board and configured to press the trigger zone;
- and
- at least one spacer structure disposed between the bottom plate and the membrane circuit board and substantially aligned with a peripheral edge of the trigger zone, wherein the spacer structure is configured to separate the bottom plate and the membrane circuit board by a distance.
A keyboard, comprising:
- a bottom plate;
- a membrane circuit board located over the bottom plate and having a plurality of trigger zones, wherein the membrane circuit board is configured to generate a trigger signal when any of the trigger zones is pressed;
- a plurality of keyswitch assemblies disposed over the membrane circuit board, each of the keyswitch assemblies being configured to press a corresponding one of the trigger zones;
- and
- a plurality of spacer structures disposed between the bottom plate and the membrane circuit board, each of the spacer structures being substantially aligned with a peripheral edge of a corresponding one of the trigger zones and configured to separate the bottom plate and the membrane circuit board by a distance.
