Reliable switch testing for the highest quality requirements
Switches play a central role in electrical devices and systems. However, even the smallest errors in their operation can have far-reaching consequences - from malfunctions during operation to safety-critical failures. Inadequate switching performance often goes unnoticed without targeted switch testing and poses a high risk to systems, processes and people. Only through precise, regular monitoring of electrical parameters such as switching points, bounce behavior or opening and closing times can malfunctions be detected at an early stage and prevented in a targeted manner. We use state-of-the-art hardware and software technology to support you in ensuring the long-term functionality and safety of your switches.

Efficient test solution for bi-metal temperature controllers
A customized, 12-channel test system was developed for a manufacturer of bi-metal temperature controllers that are installed in everyday appliances such as coffee machines and other household applications. The aim was to create a practical, automated solution that not only delivers the highest measurement accuracy, but also maximizes ease of use. The hardware was designed as a compact tabletop device - with robust screw connection technology that enables the test specimens to be changed quickly and connected securely. The testers are operated under realistic conditions, which ensures a particularly meaningful evaluation of the components. A central component of the solution is the precise recording of the contact cold resistance via an integrated resistance measuring device. This reliably detects even the smallest deviations. The entire testing process is controlled by an application that works with ProfiSignal was implemented. This guides the operator safely through every step via an intuitive user interface - from preparation to automated evaluation. The results are automatically recorded, evaluated and documented in accordance with standards - for complete traceability and reliable quality testing. The clear, visual display in the software not only makes analysis easier, but also minimizes the risk of operating errors. Another major advantage: the system has a modular structure. New inspection requirements could be integrated in a short time and with minimal effort - without lengthy conversions or expensive additional hardware. This not only saves time and money, but also makes the testing environment future-proof in the long term.
