Everything you need to know about the function, selection, and application of reversing switches – for maximum efficiency and safety.
What role does a reversing switch play in complex industrial plants?
A reversing switch is crucial for controlling the direction of rotation of electric motors, for example in conveyor systems, machine tools, or packaging lines. It enables precise motion sequences and is thus directly responsible for process safety and productivity. For ATEK customers, this means: optimized cycle times and less scrap.
How do I choose the right reversing switch for my specific application and motor power?
The selection depends on several factors: motor power (kW), nominal voltage (V), nominal current (A), and expected switching frequency. For applications with high loads or frequent switching operations, which are common for ATEK customers, robust switches with appropriate electrical and mechanical lifespans are essential. Also, consider the unerlässlich. Beachten Sie auch den wiring diagram of the reversing switch.
What do IP protection classes mean for reversing switches and when is a high protection class like IP65 necessary?
The IP protection class (e.g., IP65) indicates the degree of protection against the ingress of foreign bodies (dust) and water. A high protection class like IP65 (dust-tight, protection against water jets) is required in harsh industrial environments, as encountered in many industries of our customers (e.g., mining, food industry), to avoid failures and ensure longevity.
What advantages do modern electronic reversing switches offer over traditional mechanical variants?
Electronic reversing switches provide less wear operation, more precise switching operations, and often a longer lifespan. They also enable smoother starts and direction reversals, reducing the mechanical stress on the drive train. For ATEK customers, this means less maintenance and higher system availability, especially in combination with frequency converters.
Can reversing switches contribute to energy savings in drive systems?
Yes, especially electronic reversing switches in conjunction with frequency converters can enable regenerative braking. In this process, the braking energy of the motor is not converted into heat, but fed back into the grid. This can, as mentioned in the article, reduce energy costs by up to 20%, which is a significant advantage for energy-intensive operations in our target group. is. .
What should be considered during the installation and commissioning of reversing switches, especially in 400V systems?
The installation, especially of 400V reversing switches, must only be carried out by qualified electrical professionals while complying with applicable safety regulations (e.g., the five safety rules). A correct connection according to the wiring diagram is crucial, to avoid damage to the motor and switch as well as hazards. ATEK supports this with clearly documented wiring diagrams and technical consulting.
How does the quality of a reversing switch affect the total operating costs (TCO) of a system?
A high-quality reversing switch with high mechanical and electrical lifespan as well as appropriate certification (e.g., TÜV) significantly reduces downtime and maintenance costs . Even if the initial purchase costs may be higher, lower downtimes and longer replacement intervals lead to lower total operating costs – a core aspect of the economic efficiency of our customers’ systems.
Does ATEK Drive Solutions also offer custom reversing switches or support for integration into existing systems?
Yes, ATEK Drive Solutions specializes in custom drive solutions. This includes the selection and adaptation of reversing switches for specific requirements. Our technical consulting supports you in the optimal integration into your existing or new drive systems, to ensure maximum efficiency and reliability, in line with our mission as a system provider.
Die correct selection of a reversing switch is crucial for system efficiency and can significantly reduce downtimes as well as extend the lifespan of motors.

Introduction to reversing switches
This article discusses reversing switches and explains how their selection and application can improve the efficiency and safety of industrial drives. Approaches for optimizing drive systems are presented.
Understand core tasks and significance
A reversing switch controls, as a central component, the direction of rotation of electric motors in industrial processes. In packaging systems, for example, it enables quick direction changes of conveyor belts at hundreds of cycles per hour. The correct function is often crucial for the productivity of entire lines.
More than just reversing directions
As part of the drive system, also for three-phase applications, the selection of the right reversing switch affects the lifespan and reliability of machines. An unsuitable switch, e.g., one rated for 10,000 cycles in high-frequency use, leads to premature wear. Careful selection reduces downtimes and maintenance costs.Functionality and applications of reversing switches
Master the principle of direction reversal
A reversing switch reverses the motor direction by changing the phase sequence or polarity of the power supply, e.g., in a 400V three-phase motor. Pole-changing switches (cross switches) switch specific connections. This technique is fundamental for machines with bidirectional movements. Understanding the function allows for faster fault diagnosis.
- Enables the reversal of the motor’s direction of rotation.
- Works by changing the phase sequence of the power supply.
- Can alternatively change the polarity of the power supply.
- Pole-changing switches (cross switches) switch specific conductor connections.
- This technique is fundamental for machines that perform movements in two directions.
- A deep understanding of the principle accelerates the diagnosis of faults.
Discover diverse applications
Direction switches are used across industries: in machine tools (lathes, mills) for spindle direction control, in lifts, and in motor clockwise-counterclockwise switches for conveyor systems. Blinds drives also utilize this principle. The versatility requires an application-specific selection.Technical aspects and specifications
Pay attention to important performance parameters
Important performance data are voltage (e.g., 230V, 400V), current strength, and IP protection class (e.g., IP65). A reversing switch for a 5.5 kW three-phase motor has different specifications than one for small controls. The precise adaptation of these parameters ensures reliable system operation.
Check lifespan and certifications
Lifespan is specified in switching cycles (e.g., 300,000 mechanical cycles). Certifications (TÜV, CE) confirm compliance with standards (e.g., EN 60947), important when interacting with components like star-delta switches. Quality and tested safety are advantageous in the long term.Selection criteria and installation
Make the right selection for your application
The selection of the appropriate reversing switch is based on motor power (e.g., 7.5 kW electric motor) and environmental conditions (e.g., higher IP protection class in case of dust). Mounting dimensions and accessories should also be considered. A careful selection avoids misinvestments and optimizes performance.
- Motor power of the drive electric motor (e.g., 7.5 kW).
- Environmental conditions at the place of use (e.g., dust load, humidity, temperature).
- Required IP protection class according to environmental conditions.
- Available mounting dimensions and installation space.
- Necessary accessories such as housings or actuating elements.
- Avoidance of misinvestments through precise needs analysis.
- Ensuring optimal performance and reliability of the drive system.
Ensure safe commissioning and installation
Installation, especially of 400V variants, must be carried out by qualified electrical professionals while observing the five safety rules. A correct wiring plan is necessary to avoid damage and hazards. Safety is of utmost importance in electrical installations.Current trends and innovations
Utilize the advance of electronic solutions
Modern reversing switches increasingly use electronic instead of mechanical contacts, reducing wear and enabling more precise, smoother switching. They are easier to integrate into digital controls. This development can improve the lifespan and flexibility of three-phase systems .
