Switches to suit every requirement
Our switches can be designed for harsh environments where temperatures fluctuate significantly, extreme heights and depths, or in applications that require high levels of protection. Whatever the challenge, we will work with you to find the ideal solution. Our modular switch system is highly efficient and can be tailored to meet almost any requirement.
Everything that makes your switches unique
Adjust the switch program
The switch program can be adjusted freely in terms of function, positions and connections. This allows users to combine an infinite number of possibilities and implement a wide range of control technology solutions.
Adapt the housing
We can adapt any housing that can be represented in CAD for you, including stainless steel or cast-iron options, to provide optimal protection against environmental influences. Our products are fully EMC compliant and can be equipped with a range of handles and accessories to suit your specific needs.
Additional equipment
A total of 131 different accessories in 19 sizes offer an almost infinite number of switch configurations. From key actuators and door couplings to auxiliary contact blocks, our additional equipment is the perfect complement for all Sontheimer switches of one size. For optical or mechanical reasons, they can also be the right choice in the next-higher size.
Personalised branding
Our range of marking lasers allows us to insert your logo in the desired position in our switches.
Adaptation options for every customer interface
Thanks to our modular system, you can easily adapt our switches to suit your needs. We can create the interface and integrate it into your overall system, providing a seamless solution.
Packing and assembly services
Our portfolio includes everything from stand-alone switches to fully wired and assembled modules.
Development services for special areas of application
We provide a comprehensive service package. In addition to providing switch solutions, we also develop, produce and install complete solutions that extend beyond the switch.

Infrastructure
With regard to high-voltage switchgear, the switching speeds and switching cycles are of an extremely high level. We have developed the right switch to meet these requirements.

Renewable energies
Wind turbines are operated in hot and cold conditions. The properties of our custom-made switch ensure that it can withstand both extremes.

Communication
Radio masts in high mountainous regions are particularly susceptible to extreme weather conditions. To meet this challenge, we have designed our switch to be highly resilient.

Construction
The concrete manufacturing process generates significant amounts of dust and debris. To withstand these conditions, our switch features a steel ball handle and a steel housing with a high protection class.

Nautical applications
At extreme depths, there are vibrations and special pressure and temperature conditions. Our solution is a gold-plated contact system and a continuous switching test at -30°C.

Emergency power supply
In the event of an emergency, it is essential to ensure safe, uninterrupted shifting. To achieve this, the shifting program must be designed to accommodate a single shifting angle. Our solution addresses this challenge effectively.
