Description
The Bard HVAC 8402-128BX Limit Switch is a control component used to measure temperature in the HVAC systems. Its main operation is an electric circuit when the inside temperature is L220° F to avoid overheating. It is a 1-shot actuation mechanism, which is activated by a temperature-sensitive element at the preset threshold. Installation is fixing the switch in a place where it is exposed to the temperature and attaching it to the control circuit of the system. It provides precise over-temperature control, therefore, offering secure operation, component protection and performance in forced-air heating, cooling and air handling systems.
