  • Suitable for small and large current and voltage ranges
  • Wide product range of connectors as well as fuse and relay holders in press-fit technology

The central electrics are devices used for power distribution. We offer users a wide product range of purely passive central electrics in low-voltage range. They can for example be used as cabin control units in both small and large machines.

We have a wide range of flexible press-fit components for customer-specific developments:

  • Color and form-coded plug-in connectors with different pole numbers
  • Relay sockets in T or Maxi form
  • Fuse holders in the construction forms Mini, ATO and Maxi

Power bolts produced in solid press-fit technology are used for current consumption.


We are proud of our products and solutions, but they really reveal their true colors when used by our customers. Whether digitalized, automated or electrified – mobile machines repeatedly delight with new innovations, in particular in terms of their user-friendliness, reliability and ability to integrate into work processes. Thanks to our customers, we are delighted to present a small selection here.


Our objective is to support our customers in all aspects concerning the digitalization, automation and electrification of their mobile machines. We consider the entire machine lifecycle and develop our STW product and service portfolio in alignment with this lifecycle. The ECO system, an open and holistic approach, facilitates the cross-topic integration of STW solutions. Furthermore, our product approach facilitates functional expansion through partner offers and hybrid, integrated products based on our system module.


The STW "ECO System" is characterized through the integration of systems and products which transcend the borders between solution areas. Our partners also supplement the STW product and services portfolio for the benefit of our customers. The open nature of the product portfolio permits easy integration of the products into third-party systems or the supplementation of our system through further products by third party providers.
