Momentary Plunger Switch

Delta Systems’ Momentary Plunger Switches have great tactile feedback with snap action domes. Buttons are up/down or right/left, depending on switch orientation. All exiting wires are encapsulated, protecting them from the elements. The switch bodies are available in nut mount or snap-in versions, and both have an easy, one-step connector for quick hook-up to the wiring harness. Snap-in models have a bezel that can include molded or printed graphics and can be customized to match your panel. Snap-in models require no mounting hardware - the wing flaps snap directly into the dash panel.

Fully sealed design and excellent switches suitable for the harsh environments of marine applications.

Features & Benefits

  • Fully sealed IP67 design
  • Tactile feedback
  • Easy to install and connect
  • Off/Momentary/On or On/Momentary/Off type applications
