Abstract
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.
Claims20
An keyboard comprising:
- a key switch, wherein the key switch comprises;
- a housing;
- a stem movably located within the housing;
- a projection extending from the stem;
- a receiving switch conductor located within the housing, wherein the receiving switch conductor is operably connected to a receiver and a signal processor;
- a transmitting switch conductor located within the housing, wherein the transmitting switch conductor is operably connected to a signal generator;
- and
- wherein depression of the stem causes the receiving switch conductor and the transmitting switch conductor switch to approach each other as the stem is depressed, wherein the approach of the receiving switch conductor to the transmitting switch conductor is determined based on signals received at the receiving switch conductor form the transmitting switch conductor.
