Switches and locking systems play a key role in high technology products. They are easy to operate and therefore ensure secure handling of complex products.
For this reason, the quality of switches must not be left to chance. 100% function checks at the end of production, where the force/displacement or torque/angle of rotation curves are recorded when the switch is toggled, ensure the highest possible security.
Certain special features must be noted, especially when checking rotary switches. Two types of information are pooled simultaneously during the process and quality monitoring of this switch type.
- The toggling of the switch itself ("switch event")
- The typical switching curve (torque/angle of rotation switch characteristic curve) which is recorded highly dynamically using a contactless operating torque transducer with an integrated angle of rotation measuring system
HBM offers all necessary components in the measurement chain from one source for the secure testing of rotary switches. These include the torque transducer T20WN, which is particularly suitable for the industrial environment thanks to its technical characteristics, and the MP85A EASYswitch, the industrial process controller designed specially for reliable switch checking.
