Snap Action, Limit Switches

Snap action, limit switches are commonly used in many applications because of their reliability and durability. These switches have been around for quite some time now and are used for a variety of tasks including sensing movement, controlling the on and off state of systems and environments, controlling the timing of events, and more. As the name implies, a limit switch is used to physically activate or deactivate a certain action when it is reached. The action could be to toggle the state of a connected device, enable a circuit, or open/close a mechanical contact.Snap action limit switches are electromechanical switches with a plunger or armature that actuates its switch contact when it is either pushed or pulled beyond a certain point. This point is known as the “over-travel” and is a measure of the amount of physical movement needed to activate the switch. The over-travel is the distance or angle that the armature of the switch needs to travel for the switch contacts to be opened or closed, depending on their initial state.The working principle of a snap action limit switch is based on the actuation of a bi-metal strip, which bends when it is heated and returns to its normal position when cooled. This heat is typically generated by an electrical current running through the switch which causes the bi-metal strip to bend and actuate the switch contacts. This snap action causes the contacts to move quickly, thus allowing for a reliable “snap-action”.The main applications for snap action limit switches include motor control, machine control, and motion sensing. Some examples include controlling machines such as conveyor belts and automated production lines, as well as controlling the timing and speed of motors. They are also used to sense the movement of systems, such as the position of an elevator or the acceleration of a vehicle.Many electronic products today use limit switches as part of their safety and security features. For example, if something is blocking the movement of a machine, the limit switch can be used to detect this and shut down the operation if necessary. Limit switches can also be used in security systems to detect intrusion or tampering.In industrial settings, limit switches are commonly used as a safety measure to protect against system overloads or malfunctioning equipment. For instance, they can be used to detect high temperatures in pipelines and to shut off the flow of fuel or other hazardous materials.Limit switches can also be used in household appliances, such as refrigerators and ovens, to detect and protect against over-heating, burning, or other faulty operations.The most common type of limit switch is the “roller plunger” type, which uses a rotating cam and contact points to actuate the switch contacts. Roller plunger limit switches have become the standard for most applications since they are reliable, durable, and require little maintenance or manipulation.Overall, snap action limit switches are a versatile and reliable type of switch that has become a key component in many applications. Their precise and reliable activation points make them ideal for use in a variety of applications, from motor control to motion sensing. As technology continues to advance, limit switches will remain an integral part of many products, devices, and systems.
