Cleaning Wall Switches
Wall switch cover plates are manufactured from high quality stainless steel and
painted with scuff-resistant coatings. To clean the cover plates, use a damp nonabrasive cloth. Regular cleaning with harsh solvents or abrasive materials may
cause deterioration of the painted engraving.
Mounting Options
In addition to the mounting options on this sheet, Larco wall switches can be
mounted in any of our specially designed wall switch mounting boxes, like the
universal box shown at right. Use the guidelines included with each box for proper
installation.
Observe all manufacturers’ recommendations for safety and operation of their products. ANSI/BHMA
standards that offer specific recommendations for each type and class of automatic door have been
developed. To obtain a copy of the ANSI/BHMA installation standard, visit www.buildershardware.com
