Snap Action, Limit Switches

Snap action, limit switches are sturdy and reliable electro-mechanical switches which are widely used in many industrial applications. They are primarily used as safety devices and to control the flow of electricity in equipment and machinery.

83278063 Application Field and Working Principle

Snap action, limit switches are primarily used in industrial and commercial applications for the purpose of safety and controlling electricity flow in electrical machinery. They are designed to detect the presence of an object or a process at a specified level and then actuate a switch or a device to control the flow of electricity accordingly.

The basic working principle is simple and has been in use since the early days of electrical engineering. Basically, a limit switch consists of a body with a movable contact that is spring-loaded or tensioned. The body holds the contact in its current position, and when an object is detected, the contact moves and activates a closing circuit. This closes the switch and allows electric current to flow.

One of the major advantages of using snap action, limit switches is that they are highly reliable, economical and easy to operate. Also, they are very durable as they can work for years with minimal maintenance. These switches are commonly used in hazardous environments, since they are designed to be highly resistant to dust, moisture, dust, vibration, and heat.

Snap action, limit switches are used in a variety of applications including industrial automation, process control, and safety monitoring. In industrial automation, they are used to start and stop machines, alert operators of objects in unauthorized areas, control process and prevent unsafe conditions. In process control, they are used to sense and control the temperature in machines, detect the absence or presence of liquids, and trigger alarms when certain conditions are met.

In safety monitoring, they are often used to detect the presence of objects in personal spaces, as well as, position and velocity of machines. They can also be used in conjunction with motion detection systems to provide safety by limiting the speed of moving objects. Additionally, they are often used to detect the presence of hazardous gases, levels of insulation, and over-temperature of motors.

Snap action, limit switches come in a variety of types and styles, including momentary, rotary, and two-position switches. Momentary switches are designed to open or close for a very short period of time when actuated. Rotary switches usually consist of a knob which will rotate to open or close the switch when actuated. Two position switches are designed to close or open at two predetermined positions of rotation or translation.

Snap action, limit switches are an essential part of any control system and provide high levels of reliability and control. They offer high levels of reliability, durability, and accuracy and are easy to install and maintain.
