ESE-11SV1 Snap Action, Limit Switches Application Field and Working Principle

The ESE-11SV1 snap action, limit switch is designed to trip and break a circuit when the switch actuator reaches a certain point in its travel, before reverting to its original position. The manual or automatic resetting of the switch’s actuator is provided by a mechanical spring and is therefore dependent upon the tension of the spring and the accuracy of the reset position of the actuator.

Normally found in industrial and commercial applications, snap action switches are suitable for a wide variety of uses including the detection of limit positions, indicating the presence or absence of an object, immersion in liquid, the presence of failure conditions, etc. and for the switching of starters, circuits, lights, motors, bells and other electrical equipment.

Applications

The ESE-11SV1 snap action switch can be used in a wide range of application fields such as:

• Industrial automation
• Process control
• Food and beverage
• Robotics
• Building automation
• Medical equipment
• Aviation and aerospace

In industrial automation, it can switch starter circuits, control valves, HVAC equipment, security systems and other electromechanical apparatus. It can also be used as part of a process control workflow such as the detection of solids, liquids, or gases in pressure or temperature control systems.

Principle of Working

The ESE-11SV1 snap action switch is designed to provide an ON/OFF operation with a mechanical spring. The mechanism works as follows: when a pressure or force is applied to the actuator, it cause the movable contact to travel down until the switch trips and breaks the circuit. Once the pressure is removed, the switch returns to its original position and the circuit is closed again. Depending on the design of the switch, this can be done manually (i.e. by hand) or automatically.

Electrical rating depends on the model of switch, with models capable of carrying currents ranging from 2 Amps to 10 Amps (AC and DC). The resetting force needed to trip the switch can also be adjusted depending on the model, with some models providing a choice of either 12 or 15 Newton resetting force.

Conclusion

The ESE-11SV1 snap action switch is an efficient and reliable limit switch for a wide range of industrial and commercial applications. Its simple mechanical spring mechanism provides an ON/OFF operation with adjustable resetting force, making it a versatile choice for many applications. Additionally, the switch’s electrical rating is suitable for current ratings from 2 Amps to 10 Amps (AC and DC).
