Position Switches are specifically designed for use in mobile machinery or components, to detect the limit position of any safety oriented devices, and therefore are also called Limit Switches.
The most basic type of switch brings two electrical conductors into contact with each other with some form of actuating mechanism – such as a human finger. More complex switches contain electronic circuits which turn on or off in response to some physical stimulus, or which can sense light or a magnetic field. Limit or Position Switches are specifically intended to function in response to a machine's own motion, and are often used to set the limit to that motion by turning off the actuating power to any component in the mechanism, should it move past some predetermined point.
Position Switches are therefore used to ensure reliable shutdown of machinery and automated systems in the event of any hazard or fault, and can often operate in extreme environmental conditions. Options for Position Switches include either complete units or modular designs for building specialised versions, and the range of different plugs, pulleys and contact elements offers high flexibility and diversity in combination options.
Rowse Automation carries a full stock of Mechanical Position Switches, in standardised designs and functions that simplify storage, wiring and installation. They are an essential component in many mobile machinery applications, such as detecting hazardous movements in machine parts and monitoring protective devices. These can include laterally sliding doors and guards, or devices using rotary joints such as flaps, covers and swing doors.
