UL 1054

1.1 These requirements cover manually operable and mechanical operable special-use switches and replacement switches:

a) That are for use on direct current as well as on alternating current or on alternating current only, and

b) For which the load ratings do not exceed 60 A at 250 V or a lower potential and 30 A or 2 hp at 600 V or a lower potential.

1.2 These requirements cover special-use switches intended for use in devices or appliances which conform with the requirements applicable to such equipment. A special-use switch is intended for factory installation in equipment and is not intended for field installation or field replacement of a similar switch. A vacuum-cleaner-handle switch, a heater switch, a radio or television switch, and a through-cord switch that has more than one on or one off position are examples of special-use switches.

1.3 These requirements cover replacement switches which are intended for field replacement of special-use switches used as part of devices and appliances. Only single or double pole, single or double throw switches are covered. Replacement switches are not for use in safety circuits.

1.4 These requirements do not cover general-use snap switches covered by the Standard for General-Use Snap Switches, UL 20.

1.5 These requirements do not cover through-cord switches with one on and one off position, special-use dimmer switches, or switches constructed so that they can be installed readily in a flush-device box or an outlet-box cover or can otherwise be used in a wiring system that complies with the National Electrical Code, NFPA 70.
