Abstract
Multi-status data entry key and keyboard capable of a one-to-one correspondence between each key status and a pre-assigned signal or state, with the neutral position or status being one of the states. Each non-neutral key status is associated with a unique pre-determined signal and corresponds uniquely to a specific symbol function or operation. The implementation of this keypad in telephones, computers, cash registers and other devices is shown. Its implementation in telephones is extensively covered.
