- H01H 35/02 Switches operated by change of position, inclination or orientation of the switch itself in relation to gravitational field (tilting mercury container H01H29/20; change of position due to change of liquid level H01H35/18)
- H01H 35/06 Switches operated by change of speed (operated by change of fluid flow H01H35/24)
- H01H 35/14 Switches operated by change of acceleration, e.g. by shock or vibration, inertia switch
- H01H 35/18 Switches operated by change of liquid level or of liquid density, e.g. float switch (by magnet carried on a float H01H36/02)
- H01H 35/24 Switches operated by change of fluid pressure, by fluid pressure waves, or by change of fluid flow (wherein the change of pressure is caused by change of temperature H01H37/36)
- H01H 35/42 Switches operated by change of humidity
