A switch responsive to a pressure differential, including a pressure response mechanism for providing a pressure response in response to the pressure differential and a device actuator arranged to interact with the pressure response mechanism and to utilize the pressure response of the pressure response mechanism to actuate a device. The device actuator actuates the device to an operative state when the pressure differential is below a lower pressure differential threshold, and may actuate the device to a non-operative state when the pressure differential is above an upper pressure differential threshold.
In an apparatus exposed to a first pressure and a second pressure, a switch responsive to a pressure differential, wherein the pressure differential is equal to the first pressure minus the second pressure, the switch comprising:
A method for actuating a device, comprising:
