A key switch implements a receiving switch conductor and transmitting switch conductor in the key switch. Depressing the key switch will cause the receiving switch conductor and transmitting switch conductor to approach each other. The approach of a finger and movement of the key switch can be detected using the receiving switch conductor and the transmitting switch conductor.

Pressure sensitive key techniques are described. In one or more implementations, a device includes at least one pressure sensitive key having a flexible contact layer spaced apart from a sensor substrate by a spacer layer, the flexible contact layer configured to flex responsive to pressure to contact the sensor substrate to initiate an input, for a computing device, associated with the pressure sensitive key. At least one of the flexible contact layer or the sensor substrate are configured to at least partially normalize an output resulting from pressure applied at a first location of the flexible contact layer with an output resulting from pressure applied at a second location of the flexible contact layer that has lesser flexibility than the first location.

What is presented is a key module (120) for a keyboard. The key module (120) comprises a guide (230) for guiding a movement of the key module (120) upon actuation, at least one spring element (240) for providing a reset force upon actuation of the key module (120), a support element (250) for supporting the guide (230) and a switch unit. The switch unit comprises a housing (270) and a contact device (280) at least partially arranged in the housing (270) for establishing electric contact upon actuation of the key module (120). The contact device (280) comprises a fixed contact piece with a first contact and a contactor with a first spring clip carrying a second contact and/or a second spring clip for producing an actuation sound and/or at least one actuation portion. The contactor is integrally formed.
