1 Industrial switches Omron designs and manufactures an extensive range of high-quality limit switches that bring easier, more effective switching solutions to machines and systems. More contacts for increased functionality Compact, space-saving design without compromising safety or performance Robust construction for operating in the harshest environments Cost-effective, high-performance switches meeting the highest safety standards UL/CSA, TÜV, BIA, SUVA approvals esigned for global use Models are available with a variety of roller lever heads, as well as various types of plunger heads. Better seals, higher resistance to shock and stronger covers make these switches the perfect solution for any industrial application, even in extreme environmental conditions. These general purpose limit switches are ideal for use in applications across the industry including lifts, garages, production lines, machine tools, automotive, security, domestic goods and vending machines. hich type of switch is needed?
