Switching devices from ASA-Schalttechnik – we make industry happen
We have been developing, producing and distributing high-quality switching devices for mechanical and plant engineering since 1974. We produce tried-and-true, affordable products. Our mechanical, magnetic and electronic switching devices are available directly ex works. On request, we produce individual special solutions in small quantities for our customers.
Tried-and-tested switch technology “Made in Germany”
ASA-Schalttechnik stands for switch technology “Made in Germany” with head, heart and hand. From our headquarters in Porta Westfalica, our products are distributed from our family business to the whole world. The products have been tried and tested across multiple industries and ensure seamless processes.
Quality – a continuous process
For us, quality is a never-ending process. We test, analyse, understand, learn from, optimise and document our switching devices on a continuous basis. Our suppliers support us in doing so. The ASA team manages quality according to the zero-defect principle, resulting in durable switching devices of the highest quality. ASA-Schalttechnik’s quality management approach is certified by ZDH-ZERT GmbH and conforms to DIN EN ISO 9001:2015.
We care about the environment and sustainability
Environment and sustainability are a point of honour and a matter close to our hearts. For us, they are more than just a trend, but a daily lived reality. After all, they are good for nature and for us all. Our basic principles include waste prevention, the responsible use of raw materials in production, material recycling, and conservation of electricity, water and heating energy. Environmental protection at ASA-Schalttechnik also means that we follow guidelines and regulations such as RoHS and REACH.
ASA-Schalttechnik as a complete service provider
ASA-Schalttechnik not only develops and produces switching devices, but shows up for its customers as a complete service provider. We even go one step further. We assemble products and complete assemblies, or adapt them to customer requirements. We can realise bores, execute products in different colours and prints, or assemble connectors and cables using our very own cable machine.

We offer a substantial range of switching devices and switch technology, available ex works, for use in many different industries and applications. Our product range includes mechanical, magnetic and electronic switching devices for mechanical and plant engineering, control and automation technology, medical technology, fire protection technology, and much more. Our product portfolio includes:
- Limit switches and position switches for the control, querying and monitoring of machine processes
- Magnet switches for control and counting functions
- Level switches for the querying, monitoring and control of level or fill level statuses
- Foot switches for the activation of switching processes wherever hands-free operation is required
- Medical switching devices for use in laboratories, veterinary medicine or operating theatres

We are aware that development in the industry is rapidly progressing. That’s why our switching devices for professional applications must keep up with the pace of innovation. We are constantly further developing our products and regularly introduce new products to expand our range of switching devices and solutions.
