1971 280SE will not start

My 280SE is driven regularly and has a kill switch on the battery, so the battery should not be dead. This morning I got in to start the car and all the lights go on, the windows roll up and down, and the radio goes on, but the engine will not turn over. Everything seems to die when I try to actually start the car. Is this the battery?

Why the kill switch? Have you had similar problems before? If so, you need to isolate the circuit that is killing the battery and then which item in that circuit. This is not normal and should not happen if all is well. What kind of kill switch are you using, and how is it connected to the battery? If it is not the correct capacity, or not correctly wired, this may be all, or part of your problem.

Can you hear the starter solenoid clicking when you go to the start position? With the headlights on try cranking the engine. Do the lights dim/go out or do they stay the same brightness? Are the battery terminals corroded? I'd clean them anyway as a starting point. If the headlights go dim/out when trying to start, it is probably a battery/cable problem. If there is no change in brightness, it could be a starter problem, or an open circuit.
