Joysticks are electronic devices designed for manual control of electric circuits, by means of a contact system built into them. They play a key role in the management of various types of machinery and equipment. They provide operators with the ability to control the movement and functions of machines in an efficient and safe manner. The control lever provides for easy and quick actuation of the contacts. Depending on the type of joystick, a different number of contacts can be controlled, manually, by positioning it in different directions. Each joystick enables the control of a machine or several machines by moving the lever in two, three or more positions with a contact in each direction. Joysticks, apart from in industry and industrial production as an opportunity to control machines, are also used in everyday life in the home, office or car, such as controlling electric windows and doors, consoles, screens, directing video surveillance cameras and others.
For the correct operation and maximum usefulness of the joysticks, it is good to consider the type of joystick, the material from which they are made, whether the contacts are NO (open) or NC (closed), the maximum load they can manage as well as whether they are custodial and non-custodial.
Holding joysticks are designed to hold the position of the machine or equipment when the operator releases the joystick. This is especially useful when working with machines that require precise positioning or holding of the load. Retaining joysticks prevent unwanted movements and ensure stability and security during operation.
Non-hold joysticks, on the other hand, do not hold the position of the machine or equipment after the joystick is released. They are used to control the movement of the machine, with the operator having to hold the joystick in the desired position. This allows the operator more flexibility and control over the machine, but also requires constant attention and effort on the part of the operator.
Both types of joysticks have their advantages and disadvantages and are used depending on the specific needs and requirements of the machine or facility. Retaining joysticks are better suited for tasks that require stability and position holding, such as handling heavy loads or accurately positioning tools. Non-locking joysticks are better suited for tasks that require flexibility and precision in control, such as maneuvering the machine in tight spaces or performing complex movements.
