Wiring a circuit with 2 microswitches for 2 pedals where circuit is off under only one condition
Table 1. Required logic.

Brake   Accel   Output
up      up      on
up      down    off
down    up      on
down    down    on


This can be simplified to 

Brake   Accel   Output
up      up      on
up      down    off
down    X       on


where 'X' is "don't care".

Figure 1. Circuit to achieve required logic.

Note that there will be a momentary break in continuity when the brake pedal changes state due to both N.O. and N.C. contacts being disconnected for a moment.
