Abstract
The present invention provides a multi-stage input device. The multi-stage input device includes a keycap, a multi-stage cushion component, and a circuit board assembly. The multi-stage cushion component is located between the keycap and the circuit board assembly to support the keycap. When the keycap is depressed to a light pressing level position, the keycap triggers a multi-stage switch of the circuit board assembly, so that the multi-stage switch generates a light-pressing signal to perform a first function. When the keycap is depressed to a heavy pressing level position, the keycap triggers the multi-stage switch of the circuit board assembly, so that the multi-stage switch generates a heavy-pressing signal to perform a second function.
