Application

Suitable for indoor areas.

Description

A range of low/high voltage indoor push buttons.


Available in three models:

  • StopperLatch – Key-to-Reset - for applications where repeat activation must be controlled. Once the switch has been manually activated, it can only be reset by inserting a special key.
  • StopperPush – Momentary - for applications where momentary push and release activation is desired.
  • StopperLatch – Pneumatic - for applications where momentary push and release is required, with a holding signal timer. Pneumatic adjustable timer opens or closes a circuit and has a timed delay before reset. No electricity to operate.

All models are available in a variety of colours with space for function marking and operating instructions. It is advisable to protect StopperSwitches with an STI Euro Stopper®.


Features and benefits:

  • One year guarantee on electromechanical and electronic components.
  • Inset design on the push button helps prevent accidental activation.
  • Space available for function marking and operating instructions.
  • Designed to fit either flush or surface installations (35 mm black surface back box and flush mounting plate included).
  • Fit any standard UK-type switch socket box.
