DEFINITION

Classification: 200/61.45

(under subclass 52) Circuit makers and breakers operated by (a) the action of gravity on a part thereof when the relation of the circuit controller as a unit to the horizontal is changed and/or (b) the tendency of a part thereof to remain at rest or to continue moving at a constant rate of speed when the circuit controller as a unit is caused to be accelerated or decelerated.

(1) Note. Those circuit controllers which are actuated in response to (a) a change in direction of motion, (b) linear displacement, or (c) the attainment of a predetermined speed, without regard to the rate at which (a), (b), or (c) is accomplished are not in this subclass or in those indented hereunder, but will be found in other appropriate subclasses in this class.

(2) Note. As applied to vehicles these controllers are generally known as collision or upset switches.

(3) Note. The duration of the period of acceleration (or deceleration) may be imperceptible or minute such as when the circuit controller is jarred or vibrated.
