Relay
Impulse switch for safe disconnection

None of our devices have been produced in such large quantities and with such great success as our impulse switch. Hundreds of thousands of them have been sold all over the world. It is available in various versions and further developments. It was developed out of necessity because the progressive replacement of relay technology by integrated circuits had not yet provoked a reaction from the installation industry. The highly integrated call systems with energy-saving technology had to control power-hungry contactors to switch the bed and ceiling lighting in patient rooms, often with fatal consequences.

Together with increasing safety requirements, the protection of the patient against 230V was also far from sufficient to prevent body currents. Our impulse switch, which was actually only intended as a supplement to our own systems, was immediately absorbed by the market; the competition and almost all manufacturers of medical technology systems and light rails worldwide now rely on our product. Now that the nurse call standard DIN VDE 0834 has come into force, there is no way around our small device.
