Pressure Switches nyaropa®- HYDROSTAR

The Pressure Switch for Safety Switching • Reduction of faults, caused by Micro-Switches, to a minimum. Statistically up to 106 switching cycles without faulty switching. • Fully interchangeable to DS-307/302. - Same dimensions. • Electrical lifetime considerably increased. a) different contact design b) different contact material. Preferred application: air craft plants, lifting platforms Electrical Connection Switching symbols without pressure Function pressure increase Function pressure increase Function pressure decrease Function pressure decrease
