Description
The York S1-2985-3181 Auto Limit Switch 160°F-190°F is an essential safety part for HVAC systems. It is meant to trip off equipment like chillers, boilers and refrigeration systems when the system temperature rises to a certain level. This minimizes instances of overheating which can lead to a lot of problems like equipment failure, fire breakouts, and not forgetting the user inside the building. The switch works on a basic concept. It has a changeable component, usually a bimetallic strip or a wax pellet that changes its condition in response to temperature. When the system temperature rises to the upper limit of 190°F in this case, the element either expands or melts and makes the switch open.
