GO® Switch Leverless limit switches provide reliable, durable position sensing in the most demanding plant conditions. Unlike mechanical limit switches or inductive proximity sensors, GO Switches use a unique hybrid technology that eliminates wear and tear. As a result, GO Switches are more dependable and last longer in the toughest applications.

The GO Switch Difference

Unique hybrid technology. GO Switches have a one-of-a-kind “leverless limit switch” design that combines the advantages of existing limit switch and proximity sensor technologies. As a result, GO Switches deliver better performance in the most demanding applications.

Reliability in a variety of industries. For over fifty years, GO Switches have set the standard for mission-critical position sensing in the automotive, cement, chemical, die casting, food & beverage, hydrocarbon, manufacturing, mining, oil & gas, petrochemical, power generation, pulp and paper, steel & aluminum, tire & rubber, and water & wastewater industries.

Durability when it matters most
. GO Switches last longer in plant conditions that are hot, cold, wet, dirty, abusive, corrosive, and explosive. A wide variety of GO Switches are certified for use in all hazardous areas including Zone 0 (intrinsically safe), Zone 1 (explosion proof), and Zone 2 (non-incendive). With no exposed moving parts and no delicate electronics, GO Switches have been designed to withstand caustics, corrosives, salt water, submersion, physical abuse, vibration, and temperatures ranging from -58°F/-50°C to 400°F/204°C.

Square Series

GO™ Switch Model 11

The GO™ Switch Model 11 features sealed gold flashed contacts, no-touch sensing and snap action response in a square switch design with a 3/8™ sensing range.

GO™ Switch Model 21

Offering the same features as the GO™ Switch Model 11, The Model 21 GO™ Switch provides a smaller design. All GO™ Switch wiring options include A/C, D/C, N/O or N/C, consumes no power to operate and has no current leakage or voltage drop.

GO™ Switch Model 81

The GO™ Switch Model 81 offers end sensing and an optional Double Pole Double Throw (DPDT) contact arrangement With a 1/4™ sensing range, wiring options include; AC, DC, N/O or N/C choices.

Round Series

GO™ Switch Model 71

A lower profile version of model 12, model 22 is also available with ATEX/IECEx Zone 1, Ex ’de’ flameproof and increased safety hazardous area classification in a smaller package.

GO™ Switch Model 77

GO™ Switch Model 77 has the same great features of Models 73 and 74 but with the added benefit of a much greater length.

GO™ Switch Model 7G

The GO™ Switch Model 7G leverless limit switche offers unique options such as hermetic seal and Double Pole Double Throw (DPDT) contact arrangements.

GO™ Switch Model 7LG

The GO™ Switch Model 7LG leverless limit switch offers the same proven internal design as our other 70 Series leverless limit switches, only with the addition of Green BriteLite LEDs.

GO™ Switch Model 7LR

The GO™ Switch Model 7LR leverless limit switch offers the same proven internal design as our other 70 Series leverless limit switches, with the addition of Red BriteLite LEDs.

GO™ Switch Model LPS

The LPS is specifically designed to provide position feedback on linear control and knifegate valves. The LPS uses a hermetically sealed sensor element and is not a GO® Switch leverless limit switch design.
