Switches • Limit Switches

  Mechanical limit switches are contact sensors widely used for detecting the presence or position of objects in industrial environments. These products offer high precision in terms of accuracy and repeatability, as physical contact is made with the target. Limit switches can be modular - with a variety of interchangeable components - or a self-contained, single-piece switch. Limit switches are known for their ruggedness, simple visible operation, ease of installation and reliability of operation. Types of limit switches include: safety, single-plunger, single-home fixing, precision multiple, die cast aluminum, compact, miniature DIN, heavy-duty modular, non plug-in, hazardous location, and special purpose. Each limit switch is available with a variety of plungers, actuator heads, and contacts.
