ABSTRACT:
A multiple switch in accordance with the present invention comprises a plurality of pushbuttons that are movable between an extended and a depressed position and are biased toward the extended position. The pushbuttons are paired and each pushbutton pair is associated with an individual lockout, a releasing-latching bar (RL bar) that is common to all of the pairs, and an individual releasing-nonlatching and releasing-latching bar (RNRL bar). Each pushbutton interacts with all three members when it is depressed.
The lockout permits either pushbutton of the associated pair to be depressed individually but prevents both pushbuttons from being depressed simultaneously. As any pushbutton is depressed, the RL bar acts to release all pushbuttons previously depressed and latches the activated pushbutton in its depressed position. Finally, the RNRL bar interacts with a first pushbutton of the associated pair to release the second pushbutton of the pair if it was previously depressed and interacts with the second pushbutton of the associated pair to latch it in its depressed position. Each RNRL bar interacts with the associated pushbutton pair in conjunction with the RL bar but independent of any other RNRL bar.
