Slide switches are mechanical switches defined by their method of activation. The switch is a slider that moves (slides) from position to position. Depending on the actuator type, the handle is either flush or raised. Electrical specifications, physical size, terminal type, materials of construction, and features are important parameters to consider. Electrical specifications for slide switches include: maximum current rating, maximum AC voltage, maximum DC voltage, maximum power rating, and maximum mechanical life. Slide switch sizes are usually described as subminiature, miniature, and standard. There are many different terminal types for slide 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 slide switch bases and slide switch actuators are made of plastic, thermoplastic, or metal materials. In terms of features, slide switches may include a pilot light, illuminated switch, imprinted markings, wiping contacts, locking switch, time delay, CE certification, CSA certification, or UL listing. Dustproof, weather resistant, and waterproof slide switches are also available.
