Leviton Introduces New External Clamp Design on Pilot Light and Lighted Handle Commercial and Industrial Switches

Little Neck, December 19, 2005 - Leviton has enhanced its line of single pole and 3-way commercial and industrial pilot light and lighted handle switches with an ergonomic external backwire clamp design. The external clamp design offers streamlined installation by eliminating internal back wiring holes. The installer simply inserts the wire under the external clamp, which is now serrated for better gripping retention, and tightens the terminal screws to the proper torque value. The external clamp design is already available on several Leviton wiring device lines, including the Industrial line of V-0 MAXTM receptacles and motor starter switches and standard single-pole and 3-way switches. Leviton lighted handle switches illuminate when the load is OFF, serving as a switch locator in darkened areas. Leviton pilot light switches illuminate when the load is ON.

As with previous switch models, the terminal screws on the new devices accommodate 12-14 AWG wire and permit easy feed-through wiring. The new external clamp design also significantly eases side wiring because the terminal screws are installed securely in place and are not "floating." The external clamp makes visual confirmation that the wires are securely in place easier.

Leviton's Industrial switches feature color-coded body covers to denote amperage (blue-15 Amp, red-20 Amp, and green-30 Amp), rugged thermoplastic toggles and housings, and large silver-cadmium oxide contacts that prevent sticking, excessive pitting, and welding. They are UL 20 and UL Fed Spec WS896E listed, and CSA C22.2 No.111 certified.

The external clamp design is currently available for the Leviton 1201 and 1221 Single Pole series; 1203 and 1223 Three-Way series; CSB1 Single Pole and CSB3 Three-Way series; Canadian 18201 and 18221 Single Pole; and Canadian 18203 and 18223 Three-Way series, with additional products to follow.
