A normally open float switch is typically wired to control which component?

A normally open float switch is primarily used to control a condensate pump due to its operational characteristics and intended function. When the water level in a condensate pan rises to a predetermined height, the float switch activates, closing the circuit and signaling the condensate pump to start working. This helps to remove excess water from areas where it could cause damage or malfunction, making it essential for systems that produce condensate, such as HVAC units or boilers.

In contrast, a gas valve is typically controlled by safety mechanisms and other sensors, a vent fan is managed by different types of switches or thermostats that respond to temperature changes, and the combustion chamber does not directly use a switch like this for operational control. Thus, the use of a normally open float switch aligns perfectly with the requirements of managing a condensate pump effectively.
