	The ~~latch behavior~~ can ~~not~~ be ~~used~~ if the control ~~has a local variable~~ on the block diagram.		=== Value differences for latch and switch type controls ===

			The mechanical action not only changes how a control reacts to user input, it also affects how control values can be access from the block diagram if set to any of the '''Latch''' actions. The changes are visible when looking at the <code>Value</code> property of the control. While it is possible to just access the Boolean value for switch actions, the type for latch actions changes from Boolean to [[Variant]]. The reason for this is, that the latching behavior would cause race-conditions if it was read in multiple places on the block diagram. This is, why only the control returns the actual Boolean value, but not the property node.

			In order to access the Boolean value for latch type controls, an [[Event structure\|event structure]] must be used.

	Boolean controls have mechanical actions, which control how activation with the mouse affects the value of the control. A mechanical action allows the control to mimic certain physical actuators (e.g. a light switch or an emergency stop button).
