Robust surface-mounted switch made of durable and weather-resistant, fibreglass-reinforced thermoplastic. The switch is IP54 splash-proof and also provides additional protection against dust. Furthermore, it is resistant to chemicals and elevated temperatures and at the same time has a high impact strength (IK05). Inside the switch there is already a connected quick connection terminal for the earthing connection, which allows an even easier connection. Up to three cables can be routed through the sealing diaphragm both above and below the switch.
