Slide switches, THT, vertical

SR254

  • Miniature slide switches with 3 pin connection
  • Can be used as ON/OFF-switches or CHANGE-OVER-switches
  • End-stackable in 2.54 mm pitch
  • Solder and flux sealed base
  • Gold plated roller contacts ensure safe switching even at low currents
  • Robust and reliable switches despite of miniature size
  • Switching position A visible on the top
  • High-end alternative to jumpers
  • Can also be used as address switch for applications requiring a limited quantity of addresses

Despite their miniature size these switches are robust and reliable. There are multiple applications in industry as well as in consumer electronics. The switches are a High-End alternative to jumpers and also work as address switches for applications requiring a limited quantity of addresses.
