Snap Action, Limit Switches

Snap action, limit switches, like the 1478600-4, are contact devices designed primarily to make and break electrical circuits at precise points. They perform the same function as knobs, keys or cam-operated switches, but are much smoother and more reliable, require no mechanical effort, and are free from electro-mechanical wear and tear.Snap action switches comprise an enclosure with two contacts, one of which is fixed in the body, and the other is sprung, so that it moves relative to the body on contact with the fixed contact. The two contacts are protected from the external environment and are brought together when a certain limit of movement is attained.The 1478600-4 is a snap action switch. It has a double-pole construction and is suitable for use with low voltage systems. It is resistant to dust, water, solvents and shock, making it ideal for use in harsh environments. In addition, it is relatively low-cost and can be used in industrial and commercial applications.The working principle of snap action switches is based on the use of a snap dome mechanism. This mechanism consists of a dome shaped element which is connected by a spring to the movable contact. When limit is reached, the spring overcomes the frictional force between the movable contact and the fixed contact, causing the dome to collaps and thus allowing the contacts to touch each other. In some switches, an additional mechanical device, such as a link arm or cam, is used to control the movement of the movable contact.The 1478600-4 has a number of application fields. These include use as a safety switch on circuit breakers and control panels, as a limit switch to protect machinery from damage, as a signal switch to indicate door opening/closing, and in robotic and industrial automation applications.The 1478600-4 is also a durable, reliable switch. It has a long life expectancy of up to two million operations and is rated for an array of temperature and humidity conditions. This makes it suitable for use in a wide range of applications.The 1478600-4 has a number of advantages over other snap action switches. It has a low-height design, so it can be installed in tight spaces, and its dual-pole construction offers increased safety and reliability. In addition, it is cost-effective and offers a long life expectancy.The 1478600-4 is a versatile and reliable switch which is suitable for a variety of industrial and commercial applications. It is able to withstand harsh environments and provides precise, measured control over the circuits it is connected to. As such, it is a cost-effective and reliable solution for a wide range of applications.
