Abstract
Seven or some other number of individually operable push buttons are provided to carry out control functions of an automotive heating, ventilating and air conditioning system. The push buttoms are movable between extended and depressed positions and are biased toward their extended positions by individual return springs. A latching mechanism is provided for latching any selected push button in its depressed position while unlatching the other push buttons. An array of slidable lockout blocks prevents simultaneous depression of more than one push button, by providing only enough clearance space in the array to accept one lockout penetrating member on one push button at a time. The array is lightly spring biased to prevent rattling of the lockout blocks. Two biasing springs are compressed between the endmost pairs of lockout blocks at the opposite ends of the array.
