WA170 Mechanical Float Switch

The WA170 Mechanical Float Switch offers a reliable low current control for AC and DC applications in potable water, wastewater, and sewage.

• Overview

  FEATURES

  • Mechanically activated, snap action contacts
  • High impact, corrosion resistant polypropylene float housing
  • Low current, non-arcing applications
  • UL Listed for use in non-potable water and sewage
  • CSA Certified

  The internal switching mechanism has sealed gold cross-point contacts for reliable low current operation. Common applications include: alarm dialers, pump controllers, SCADA systems, intrinsically safe barriers, solar applications, and other low current control and alarm applications.

  Models to Meet Your Needs
  We offer a Normally Open (NO) model for high level applications. This model's control switch turns on (closes) when the float tips 45 degrees above horizontal signaling a high level, and turns off (opens) when the float drops 45 degrees below horizontal. We also offer a Normally Closed (NC) Model for low level applications. This model's control switch turns on (closes) when the float drops 45 degrees below horizontal signaling a low level, and turns off (opens) when the float tips 45 degrees above horizontal.
