Positions 1, 3 and 4 are isolated from position 2 by the means of a lock over the vertical axis of the switch actuator. The actuator has to be pushed in to unlock (approx. 4.5mm, maximum travel 6mm), only then positions 1, 3 and 4 can be selected. This locking feature is spring loaded – the switch actuator returns to locked position when released by the operator and the current switch position is 2.
Position 1 is spring loaded to return to position 2 when selected and the switch is released. The spring return position can be held in place by a holding solenoid, until the power to the solenoid is cut and the switch returns to position 2.
Those features completely replicate the behaviour of the Boeing 737 engine start switches.
