Snap-action switching element Control Switch Switching system

Contact cleaning path 2 x 0.6 mm

02

Is equipped with double-break jump contacts. Owing to the large cleaning path, outstanding self-cleaning is possible. The multilayer Mechanical lifetime contacts are designed for universal use. They are gilded with a 2 million cycles of operation 2 μm gold coating. Each snap-action switching element comprises a NC (normally closed contact) and a NO (normally open contact).

Slow-make switching element

The double-break switching system can be supplied for the following switching functions: 1 normally closed, 1 normally open or 1 changeover contact with or without overlap. The normally closed contacts have forced opening according to DIN 0660, IEC 60947-5-1 and DIN VDE 0113. The switching element exhibits high reliability due to its H-contact system with relative friction. The normally open and normally closed contacts can be used electrically separated. The standard version is ideal for high breaking capacities. For lower capacities a special version can be supplied.

Application guidelines

44 01

Suppressor circuits When switching inductive loads such as relays, DC motors, and DC solenoids, it is always important to absorb surges (e. g. with a diode) to protect the contacts. When these inductive loads are switched off, a counter emf can severely damage switch contacts and greatly shorten lifetime. Fig. 1 shows an inductive load with a free-wheeling diode connected in parallel. This free-wheeling diode provides a path for the inductor current to flow when the current is interrupted by the switch. Without this free-wheeling diode, the voltage across the coil will be limited only by dielectric breakdown voltages of the circuit or parasitic elements of the coil. This voltage can be kilovolts in amplitude even when nominal circuit voltages are low (e. g. 12 VDC) see Fig. 2.

The free-wheeling diode should be chosen so that the reverse breakdown voltage is greater than the voltage driving the inductive load. The DC blocking voltage (VR) of the free-wheeling diode can be found in the datasheet of a diode. The forward current should be equal or greater than the maximum current flowing through the load. To get an efficient protection, the free-wheeling diode must be connected as close as possible to the inductive load!
