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

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
