Safety Technology International SS2003 Key To Active Switch

The Safety Technology International SS2003 Stopper Station is a red, key-to-activate push button that prevents unauthorized or accidental activation of connected safety equipment by requiring a key to operate. It sits in STI’s Stopper Station family and is offered in variants such as SS2003NT-EN (Stopper Station Push Button, No Cover, No Text Label, Red) and SS2003EM-EN (S/Station – Red, Key-To-Activate Emergency), reflecting different mounting or labeling configurations. Common applications include guarding emergency activation points or safety interlocks in facilities where tampering or inadvertent activations must be avoided. The Stopper Station concept adds a keyed activation mechanism to deter misuse while still delivering a clearly visible push-button interface when access is granted. For installation and wiring details, STI provides data sheets and installation instructions for the SS2xxx Stopper Station line, and distributors list SS2000-series as the core family of keyed activation safeguards.
