发明名称 PROGRAMMING SWITCH ASSEMBLY FOR COMMUNICATING TERMINALS
摘要 <p>PROGRAMMING MEANS FOR COMMUNICATIONS TERMINALS Programming of a communications terminal is carried out by insertable programming members carrying a plurality of actuators. Each actuator has at least one and usually two actuating members which engage with a circuit to modify the electrical characteristics of the circuit. The actuating members themselves may contact conductor paths, connecting them selectively to a ground conductor, or interconnecting two conductor paths. The actuating members may actuate indirectly through an intermediate member. Actuating members can be at predetermined different positions along an actuator. Typically one programming member is associated with a push-button, the programming member, for example having two columns of four actuators. On depressing the push-button, the particular coding is rapidly scanned by the electronic circuitry and the particular service associated with that code is provided.</p>
