WA170 MECHANICAL FLOAT SWITCH
Low voltage mechanically-activated float switch for low current panels and alarms

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, and passed NSF Standard 61 protocol

Mechanical Float Switch Product Description

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