Plunger Switches
Delta Systems' Plunger Switches are used to sense the position of mechanical linkages and control levers. Wiping action helps to clean the contacts during use, keeping contact resistance lower and extending switch life in rugged environments. One to three independent electrical circuits are available. Our switches are easy to design into your application with versatile mounting styles for multiple panel thicknesses and mounting locations.
Typical Applications Include:
- Outdoor Power Equipment
- Utility Vehicles
- Power Sports
- Construction
- Farm & Agricultural
- Asphalt Pavers/Concrete Mixes
- Light Industrial
- Material Handling
- Off-Highway Vehicles
- Mining

Sealed Plunger Switches
We designed our sealed plunger switches for applications where the switching current is low (<100 mA, requiring clean contacts for reliable switching) and/or exposure to moisture and contaminants is high. They are ideally suited for electric-powered mowers and off-highway vehicles, as well as products with >2000-hour expected life, like commercial outdoor power, agricultural, construction, and light industrial equipment.
