Ready to assemble out of box, the UB-1 has everything required to provide what the customer wants in one convenient package. This single-gang momentary button has two sets of form “C” contacts to cover almost all electrical combinations required. The faceplate is constructed of cast aluminum and is slightly oversized to cover old plate installation marks. The UL/cUL-listed button offers more than 300 combinations in one package for the price of a standard one configuration button. A universal pneumatic button (UB-1PN), universal touch-free button with NoTouch technology (UB-1TF) and a 2-in. universal button (UB-2) are also available.
