When you have lots of electrical equipment plugged together, the last thing you want is for plugs to slip out of their sockets. However, heavy-duty equipment can often mean heavy-duty cables that are weighty, and that can put strain on connections. For these situations, the Leviton company has invented a system of interlocking plugs. Leviton plugs feature large circular heads that contain three slightly-curved prongs arranged in a circle. One of these prongs has a latch sticking off of it, making it different from the others. When the male plug goes into the female socket, there is only one way that all three prongs will fit in--and once it, a slight twist clockwise locks the two ends of cable together. As a result, you have a very strong connection that is all but immune to accidental unpluggings. That's why Leviton plugs are so popular for theatrical and industrial light and sound equipment. When a thousand lights are hanging 200 feet over a stage, the last thing you want to have to do is double-check that all your plugs are in place. Locking plugs are just one of many electrical products produced by Leviton. In addition to this well-known model, the company makes many other kinds of plugs, sockets, switches, and dimmers--many of which are used for a variety of lighting applications. When you need electrical connections that will never fail you, look no further than Leviton. |
