RS PRO Auxiliary Contact - 1NO/1NC, 2 Contact, DIN Rail Mounting

Need a way of easily controlling your primary switching equipment between the on and off positions? The auxiliary contact from RS PRO is designed to act as a secondary switching device, so you can move data from your circuit to a logic controller or standalone hardware control unit.


  • Contact voltage rating of 240 V AC
  • Suitable for mounting onto a German Institute of Standardisation (DIN) rail
  • Normal state configuration of 1 Normally Open (NO)/1 Normally Closed (NC)
  • Two contacts
  • Double pole (DP) and throw configuration

This electro-mechanical product is often used with components such as contactors, circuit breakers and switches. For quick and easy installation, it can be mounted onto a DIN rail that’s approved by the German Institute of Standardisation. When you need to create a more complex switching system, you can also install it by fitting one block on either side of your switching device.
Like all of the RS PRO range, this auxiliary contact has been tested for durability and consistency. It’s typically found being used in commercial environments, including offices, industrial plants and engineering facilities.
