DEFINITION

Classification: 200/43.01

SWITCH ACTIVATION INHIBITOR (e.g., UNAUTHORIZED INADVERTENT USE PREVENTION):

(under the class definition) Devices having structure to prohibit or restrain the operation of a switch actuator including for example coded elements (e.g., combination codes), locks or other circuit completing means.

(1) Note. The term "switch" is a device for making or breaking an electrical circuit and it normally activated by an "actuator". The actuator may take many forms such as button, handles, keys or some other type of element. A "coded element" may be in the form of a special tool, key, combinations such as permutation codes or combination locks.

SEE OR SEARCH THIS CLASS, SUBCLASS:

5+, and 50.01+, for interlock switches which have the actuator blocked depending upon the condition of the plug, the switch housing or another switch.

304, and 333, for switch shields which limit access to the actuator but which do not block the actuator or prevent access to the actuator.
