Palatine, Ill. —Harmony XB4 range of 22-mm metal pushbuttons, switches, and pilot lights use ergonomic design that simplifies installation, improves appearance, and requires less panel space. The body of the pushbutton unit comprises a metal-mounting collar and one or more electrical blocks. Special protection circuits guard the LEDs from electrostatic discharge, capacitive coupling, and electromagnetic radiation. Three wiring options—screw clamp terminals, molded plug-in connectors, or pins for printed circuit boards—are said to make installation fast and easy. Snap-in color caps and clip-on contact blocks ease modification in the field. www.squared.com
