The Crash switch (also know as Crash sensor) is a sensor which is able to detect if it is pressed or not pressed. The state of the Crash switch can be detected and can be used to trigger events or conditions in scripts. Support for this sensor is found in mDesigner.
Compatible Pins
The following pins on the Hub or mCenter+'s Hub support this module:

Blocks
Digital Read Pin
This block reads the state of the pin. In Arduino, this is known as a digital read (digitalRead). A value of either 0 or 1 will be returned.
- When Crash switch is NOT PRESSED, 1 is returned.
- When Crash switch is PRESSED, 0 is returned.
- Pin Number - the pin number to read from.
Pin Is
This block reads the state of the pin, then compares it to the configured state.
- If the state of the pin DOES MATCH the configured state, then this block returns true
- If the state of the pin DOES NOT MATCH the configured state, then this block returns false
- Pin Number - the pin number to read from.
- State - state to match in order for this block to return true.
- HIGH tests if the Crash switch is NOT PRESSED.
- LOW tests if the Crash switch is PRESSED.
