Go Switch by Topworx

Leverless Limit Switches built to last in the most demanding environments

GoSwitch 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 technology that eliminates wear and tear. As a result, Go Switches are more dependable and last longer in the toughest applications.

We are a factory authorized distributor for Go Switch. All of our products are brand new and covered by the Go Switch guarantee.

Go Switch offers 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-incendiary). 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 extreme temperatures.
