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

Configurations
Sealed Plunger Switch
We've upgraded our popular plunger switch product line, introducing a new sealed interior design that keeps out dirt, water, oil and other contaminants that cut part-life short. These sealed switches--that follow the same form, fit and function as the original plunger line--are crafted to perform even under the exposure to harsh environments over long period of time.
This technology is part of Delta's overall move toward developing IP67-rated sealed solutions for OEMs in markets such as Outdoor Power Equipment, utility vehicles, agriculture, light industrial, marine and more. For our customer partners, an investment in sealed components provides maximum protection for equipment operators, particularly in safety applications where there's no room to compromise on reliability. It also lowers warranty issues and returns to OEMs and dealers, freeing dealers from excessive time spent diagnosing problems, making repairs and unnecessarily replacing functioning parts with new parts (swapnostics.)
Features & Benefits
- Fully sealed IP67 design
- Easy to install and connect

MINI Plunger Switch
Delta Systems' Mini Plunger Switches are sealed, miniature switches with proven reliability in wet, caustic environments. Completely encapsulated at the wire lead exits, Delta’s Mini Plunger Switches withstand water submersion to depths of 10 feet making them perfect switches for outboard motors, marine equipment and boats, off road vehicles, etc. Available in various mounting configurations, wire length to fit your application. They can also be used as a sensor switch for proximity.
Features & Benefits
- Proven reliability in wet environments
- Fully sealed to IP67
- Double O-ring design at plunger and backed sealed with encapsulant
- Nut and screw mount configurations available

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
