Switching occurs when body axis is near horizontal.
Maximum included angle is 9°
Tilt switches "make" when the electrode is tilted below horizontal and "break" when tilted above the horizontal. Total travel from "make" to "break" is the "Maximum included angle". The component to which the switch is attached must have a total tilt angle greater than the "Maximum Included Angle" for proper operation. "G" series switches are mercury-to-mercury.
