Snap Action, Limit Switches

Snap action limit switches is a robust electromechanical device principally used, and designed, to control the motions of labelled machinery. This type of mechanical switch operates by quickly snapping from one position to another with a definite force and against the resistance of an operating spring, which is fixed against the outside of the switch.

The ESE-58L61A snap-action switch, one of the many types of limit switch created by the American manufacturer Eaton, is geared predominately towards applications within the automation and process control industries such as PLCs and industrial equipment. It utilizes an latching armature and snap-action actuator which effectively control the movement of the switch. When activated, this device can close or open an electrical circuit. It is a reliable and accurate switch, due to its reliable construction and design.

One of these features is the material used to engineer the switch; the housing itself is molded from extremely durable yet lightweight materials, such as glass-filled thermoplastics, brass, zinc, and nickel-plated steel. As for the various components inside the device, the materials range from plated steel and zinc to brass, stainless steel, and plastic. Furthermore, the assortment of terminal screws that come alongside the switch are made from nickel-plated steel.

ESE-58L61A is available in two switch designs, spring-loaded and momentary. The spring-loaded switch contains numerous contact points and is used for duties including marking the positions of machines and their components. The momentary switch is composed of one pair of contact points and used primarily for monitoring the running cycle of machines and keeping track of their positions. In effect, it acts as an on/off switch that constantly monitors the progress of a machine.

In addition to its strong construction and reliable design, the ESE-58L61A benefits from a variety of features that enable it to maximize reliability, accuracy, and in particular, total life. For example, the switch contains small contact springs at each of its contact points which increase electrical contact capacity. The contacts themselves are composed of gold-plated elements which guard against oxidation and facilitate better contact between parts. In addition to this, the switch is outfitted with a dust-proof cap and a rubber boot to prevent the entry of water and dust into the switch system. In doing so, these additional features ensure that the switch is well-protected from the environment, and remains in its original form for much longer.

Apart from being used within the industrial sector, the ESE-58L61A snap-action limit switch is also suitable for various other applications such as motion controllers, robots, smoke detectors and temperature monitors. In total, the switch provides a reliable and ample solution to many automation and process control operations, making it an ideal choice for a vast array of industrial and commercial operations.
