To better satisfy the needs of American customers, SecuControl has developed a new Safety Test Switch ST Switch which both features characteristics of SecuControl's FTL and of the commonly used FT Switch.
As for the FTL, the ST Switch likewise works with individual disconnect pins which can be inserted into the test position to separate the circuits from the system side to the device side. In contrast to the FTL, the ST Switch adopts the cabling connection in the back from the FT Switch.
The front side of the ST Switch is completely fingersafe which completely precludes that the operator accidentally touches any of the live circuits. In contrast to the FTL, the ST Switch has integrated status windows which indicate whether the internal contacts are open or closed. Hence, it is totally obvious to the operator when to start testing, even if he is not yet familiar with the operating principle of the ST Switch. The cabling connections at the back are copied from the FT Switch and hence offer maximum convenience to most technicians and engineers. The ST Switch features integrated banana jacks which connect to all commonly available banana plugs in order to directly inject simulated values on the test switch.
