Trane SWT2326 SPST N/C Low Level Float Switch

The Trane SWT2326 SPST N/C Low-Level Float Switch is a small but essential part of the Trane condensate pans or drain lines. As a liquid level indicator, the switch is ‘normally closed’, that is, it makes an electrical circuit when in its dry state. In the pan or drain line, when the liquid level goes up and crosses a particularly low level, the float within the switch causes a mechanism that opens the circuit. This usual break in the electrical flow may communicate instructions to the HVAC system to turn off, to prevent future overflows and water damage. This Float Switch is an essential component of an HVAC system that helps protect it from water damage and helps it run safely.
