Thermostatic Switches

Thermostatic switches are devices used to control temperature by automatically turning on or off a heating or cooling system based on the set temperature range. They work by measuring the environment's temperature and comparing it to the set temperature range. If the temperature exceeds the range, the switch will either turn the heating or cooling system on or off to maintain the desired temperature.

Types of Thermostatic Switches:

There are two main types of thermostatic switches: electromechanical and electronic.

Electromechanical thermostatic switches use a bimetallic strip to sense temperature changes. When the temperature changes, the strip bends, which triggers the switch to turn on or off. These switches are reliable and durable but can have a limited temperature range.

Electronic thermostatic switches use a sensor to detect temperature changes and a microprocessor to control the switch. These switches can have a more comprehensive temperature range and are more precise than electromechanical switches.

Applications of Thermostatic Switches:

Thermostatic switches have a wide range of applications, including:

  • HVAC systems: Thermostatic switches are commonly utilized in ventilation, heating, and air conditioning (HVAC) systems to maintain a comfortable temperature in a building.
  • Automotive industry: Thermostatic switches are used in vehicles to control the engine's temperature and prevent overheating.
  • Refrigeration systems: Thermostatic switches are used in refrigeration systems to maintain a constant temperature and prevent spoilage of food or other perishable items.
  • Industrial equipment: Thermostatic switches are used in industrial equipment to control the temperature of machinery and prevent overheating or freezing.

Advantages of Thermostatic Switches:

Thermostatic switches offer several advantages, including:

  • Energy efficiency: Thermostatic switches help to save energy by only turning on heating or cooling systems when necessary.
  • Cost-effective: Thermostatic switches are relatively inexpensive and can help to reduce energy bills over time.
  • Improved comfort: Thermostatic switches can help to maintain a comfortable temperature in a building or vehicle.
  • Increased safety: Thermostatic switches can help to prevent overheating or freezing, which can be dangerous in specific applications.

Thermostatic switches are essential to many heating, cooling, and temperature control systems. With their precision, energy efficiency, and ease of use, these switches are essential for maintaining a comfortable and safe environment.

Selco OM Series Bi-Metallic Thermostats Professional range of OM series thermostats from Selco. The OM range switches utilise a snap-action bimetal disc, electrically and thermally isolated from the switch. The thermostats contacts are normally closed and open on rise when surface or ambient temperature set point is reached. The circuit remains open until the manual reset button is depressed at approximately 30% below operating temperature. All models are highly reliable and excellent quality. Thermal Switches
