Snap Action, Limit Switches 1478609-4 Application Field and Working Principle

Snap action switches, also known as limit switches, are electro-mechanical devices used in controlling the on/off of a power supply. They are most commonly used in industrial control systems to detect the position of moving parts of machines, actuators, or other mechanical devices. They are also very suitable for environments where water, dust or other corrosive elements are present, or where precision measurements or data recording is required. The 1478609-4 limit switch is specifically designed for these types of applications.This switch is manufactured by the Honeywell company and is a double-pole, double-throw model. A double-pole switch is composed of two separate sets of electrical contacts, which are connected in parallel and fold into a single unit when triggered. When this happens, the contacts hold the current flowing in the circuit steady, making it easier to control the amount of power that is supplied. The double-throw (DPDT) switch can also be configured as a momentary switch and with either a normally open or normally closed contact setting. In the normally open configuration, the contacts are open until actuated and when released, will return to the open position. Alternatively, in the normally closed configuration, the contacts are closed until actuated and when released, will remain closed until manually opened.The 1478609-4 limit switch has a 2 inch actuation force and a maximum voltage rating of 277 volts AC. This makes it suitable for a wide range of industrial applications. It also features an all-metal construction, including an enclosed metal housing encapsulated with a rubber seal to protect it from dirt and corrosion.In addition to its mechanical features, the 1478609-4 also features an internal circuitry design that is extremely reliable and capable of providing a high degree of accuracy. The internal design includes a snap-action contact spring and three separate LED indicators that indicate the status of the switch. The first LED will light up when the switch is actuated, the second will blink when the switch is released, and the third will flash when an over-current is detected. This is useful for monitoring the functionality of the switch and can also be used to detect any type of failure while the switch is in operation.The 1478609-4 switch is a great choice for industrial control applications as it is highly reliable and cost-effective. It is also built to be extremely durable and is rated for up to one million actuations. Whether you need to detect the position of a moving part or perform precision data recording, this switch should meet all your needs.
