Plunger Switches
Delta Systems' Plunger Switches sense the position of mechanical linkages and controls and can be incorporated into your application by using one of our mounting configurations. The patented wiping action switch contact prevents carbon buildup, keeping contact resistance low and extending switch life in rugged environments.
Feature & Benefits
- Easy to design into your application
- One or two independent electrical circuits
- Wiping action internal contacts are self-cleaning to prevent carbon build up and increase life
- Versatile mounting styles for multiple panel thicknesses and mounting locations
- Years of proven reliability in a wide variety of applications

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
