Technical Remarks
■ Switching function increasing pressure: contact switches from 1-2 to 1-3.Switching function decreasing pressure: contact switches from 1-3 to 1-2.
■ Notice: Too-high currents can damage contacts. Inductive or capacitive loads must be equipped with appropriate spark-quenching!
■ The microswitch has silver-plated contacts.
