Henry Williams offers two types of electro-mechanical treadle switches which provide a safe operational environment throughout the rail infrastructure and are designed to detect train movements and provide signalling control.
The treadle or electromechanical switch provides detection at a given point on he passage of a train or single vehicle travelling at speeds of up to 260 km/hour with either uni- or bi-directional control.
Henry Williams after-sales service care is available to extend the life and maintain the high reliability of the treadle switch by refurbishing existing units and replacing all wearing components at a fraction of the new unit cost.
