Choosing an Electrical Switch

Sanitary Finger-Touch Switches
With just a light touch, these switches turn circuits on and off in sanitary areas—even when you're wearing gloves. They're ideal for environments that require frequent cleaning, such as food and pharmaceutical plants. Their smooth, crevice-free surfaces are easy to clean and prevent bacteria buildup. Rated IP69K, they withstand high-pressure, high-temperature washdowns. They help you comply with European Hygienic Engineering and Design Group (EHEDG) sanitary standards.
These switches use IO Link, so you can change settings, view outputs, and receive error messages from a connected programmable logic controller (PLC) or computer. Commonly used on production lines, they alert your team to equipment issues as soon as they occur.

Sanitary Level Switches
Detect when oil rises on water, foam forms on beer, and tanks empty, triggering pumps and valves in food and sanitary lines. These switches are 3-A and European Hygienic Engineering and Design Group (EHEDG) certified since they’re easy to keep clean. Highly polished, they prevent bacteria from growing. They also stand up to hot spraying water, chemicals, and cleaners common to food plants, thanks to their PEEK probe, stainless steel body, BSPP threads, and IP ratings. Their IP67 rating also means they won’t fail if under water temporarily.
To connect to automated systems and remote displays, these switches work with IO Link and 4-20 mA analog output, making them good for hard-to-reach areas. Program the colors on the LED indicator to tell you what the switch is sensing.
USP Class tested, the plastic in these switches won’t leach chemicals. They’re also C-UL listed and CE marked to meet Canadian and European safety standards.
Use quick-clamp adapters to connect these switches to quick-clamp sanitary tube fittings.
Note: Solids and liquids must have a dielectric constant of at least 1.5 to detect them.
