Snap action switch S870 - For demanding tasks
One feature of snap action elements is the switching speed independent of the actuation speed. This indirect switching operation is achieved by a snap action mechanism allowing a defined switching action. In such a way the S870 is excellently suited for low actuation speeds, e.g. in motors or spindle limit switches. The S870 is provided with a positive opening mechanism. Even after a short circuit the welded contact piece opens, for this reason the snap action switch is built in safety circuits... (read more)
