How to implement the Tactile switch Logic and the LEDS Both Functionalities

For this circuit, how can I implement the tactile switch functionality using the dual-LED feature? Can any one explain how the circuit should be designed for a 28V input? I am unable Implement this Logic
Like My requirement is 28V I am getting upto 42mA So This switch Should Receive and that will be working like the Tactile and need to Glow the Once pressed one will glow if anoother Press other LED should Glow . How to Implement This Logic
