Snap action and limit switches are two types of switches used in a wide range of applications. Snap action switches, also known as snap acting or snap action switches, are momentary contact switches that can act quickly and make or break electrical connections in a fraction of a second. Limit switches are commonly used as limit switches to shut off machines that reach a certain point or temperature.

Snap Action Switches

Snap action switches feature a helical spring that contains a flat, pitted contact point. When the switch is activated, the contact point snaps from one end of the helical spring to the other. This snap action allows the switch to make and break contact in a much shorter time than typical toggle switches. These switches can be used to control both AC and DC currents, with current ratings typically ranging from 0.3 amps to 15 amps in most applications. In addition, these switches can be designed to withstand surges of up to 350 amps.

These switches are often used in applications in which a high-speed response is required, such as in computing, imaging, and printing devices. They can also be used as motor starters, limit switches, air conditioning systems, and a variety of consumer appliances. With their fast response time and their durability, they are an ideal choice for many applications.

Limit Switches

Limit switches are commonly used as limit switches, which are used to shut off a machine if it reaches a certain point or temperature. These switches are designed to shut off power and stop the machine from running when it reaches a certain point. Limit switches are typically used in a variety of industrial applications, such as manufacturing, packaging, and chemical processing. Unlike snap action switches, these switches are designed to be robust and operate at a lower speed.

Limit switches come in various styles, such as toggle, plunger, deadman, and foot-operated. These switches are usually designed to handle higher current ratings and also feature a wide range of switching cycles, making them ideal for applications in which extended periods of operation are required. Limit switches can be used to control motor starters, valves, and other machinery in a wide range of industries.

83264033 Application Field and Working Principle

Snap action and limit switches both have a wide range of application fields. In general, snap action switches are suitable for applications where fast response time and durability are required, such as in computing and consumer appliances. Limit switches are mostly employed in industrial applications, such as in chemical processing, manufacturing and packaging.

The working principles of these two types of switches are relatively simple. Snap action switches feature a flat, pitted contact point that is released when the switch is activated. When the contact point is released, it creates a sudden open or close action, which allows the switch to control the current or voltage in a fraction of a second. Limit switches, meanwhile, employ a toggle, plunger, deadman, or foot-operated mechanism to shut off power and stop the machine from running.
