Ball Switches – J4 SeriesCPI’s line of sealed roller ball switches are made of 100% stainless steel and boast a patented sealing mechanism that makes them 100% waterproof over millions of cycles. Variations including custom mounting for PCB’s or extended temperature range operation with our J4 B series models. All our ball switches come with pre-integrated and sealed leads in specifiable lengths, and can be ordered in normally open/closed configurations. Extended temperature switch versions are rated to operate from -40F to 302F.
Ball Switch Construction and Customization
CPI’s ball switches utilize a patented “exclusion seal” which protects the operation of the switch under highly adverse conditions. The J4’s patented ball carrier design actually prevents contaminates such as mud, dirt, ice, hardened sand, dust, etc. from jamming the ball even when it is depressed.
These switches are also ideal for heavy industrial equipment applications that are subject to the same conditions. The switches are completely submersible and are unaffected by water, salt spray, humidity, dirt, dust, sand, icing, oil, shock and vibration, or power washing operations.
CPI’s J4 Ball Switch Applications
The robust nature of this switch design have made it go-to product for many industrial and military systems.
- Watertight hatch door closed
- Hydraulic valve position detection
- Neutral Safety detection in Military Vehicles
- Cab Down detection for trucks and transports
- Agricultural and farming equipment where it survives when exposed to corrosive chemicals.
- Door alarm detection
- Parking Brake Detection
- Misc Safety alarm applications
