Rocker switches are actuated by a standard or dual rocker or paddle. Electrical specifications for rocker switches include: maximum current rating, maximum AC voltage, maximum DC voltage, maximum power rating, and maximum mechanical life. Length or diameter, width, and panel thickness are common dimensional specifications. There are many different terminal types for rocker switches. Examples include: feed-through style, wire leads, solder terminals, screw terminals, quick connect or blade terminals, surface mount technology (SMT), straight PC pins, right angle PC pins, and side PC pins. With regard to materials of construction, most rocker switch bases and rocker switch actuators are made of plastic, thermoplastic, or metal materials. In terms of features, rocker switches may include a pilot light or illumination, imprinted markings, wiping contacts, locking mechanism, time delay, CE certification, CSA certification, or UL listing. Dustproof, weather resistant, and waterproof rocker switches are also available.
