ZS 80 3O/1S WVD - Emergency Cable Pull Switch with 3NC / 1NO contacts, water tight collar

The ZS 80 3O/1S WVD is a robust pull wire switch designed for long conveyor and machinery applications where a continuous pull wire control function is required. The enclosure is made of aluminum die cast with a durable cover, providing a solid mechanical construction for industrial environments. The unit typically supports long wire runs (for example up to around 100 m / 328 ft, depending on installation and wire routing) and includes both wire pull and wire slack/break detection via its internal switching mechanism. It features a position indicator and integrated emergency-stop push button on the housing. The switch uses slow action contacts with three normally closed and one normally open contact (3 NC / 1 NO), allowing multiple control signals from a single device. Cable entry options and terminal connections are designed for straightforward wiring in conveyor and process equipment control systems.
