Here you can learn about how limit switchboxes work, their key advantages, technical specifications, and typical industry uses -vand browse our full range of products.

How do limit switch boxes work? 
Limit switchboxes are mounted to valve actuators to provide a visual and/or electrical indication of valve position. They typically house mechanical or proximity switches, terminals, and a position indicator, allowing integration with plant control systems for monitoring, automation, and safety interlocks.
Advantages of limit switch boxes...
• Combined visual and electrical position feedback
• Protects switches in a sealed housing
• Integrates easily with control systems
• Durable and low‑maintenance design
Technical Parameters:
Temperature Range
Typically –20 °C to +80 °C Extended‑temperature models: –40 °C to +120 °C(Dependent on enclosure and seal materials)
Size Range
Actuator interface typically ISO 5211 compliant
Materials
Aluminium, stainless steel, engineered polymers, elastomers (NBR, FKM)
Industry Application:
EFW
Oil & Gas
Power
