Robust surface-mounted switch socket outlets Combination of durable and weather-resistant, fibreglass-reinforced thermoplastic material. Switch and socket are IP54 splash-proof and provide additional protection against dust. Furthermore, they are resistant to chemicals and elevated temperatures and at the same time have 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.
