Snap Action, Limit Switches

Snap action, limit switches are fundamental electromechanical devices found all throughout the industrial, medical, and commercial sectors. They are an electronic switch that senses when something has moved or shifted and powers or interrupts the flow of an electric current or medium as a result. The AM1704K is an example of such a switch and its application fields and working principle will be discussed in detail below.

AM1704K Application Field

The AM1704K is a snap action, limit switch that is widely used in many industrial fields, such as robotics, machine tooling, motion detection, product inspection and automation. It is also widely applied in medical and commercial applications such as video and audio production, food processing, retail automation and metering.

The AM1704K is specifically a rotary limit switch. It is designed so that when a rotary motion is produced, an electrical impulse is sent and an electrical circuit is completed or broken depending upon the respective design of the switch. This mechanism allows the user to establish a preset limit on a machine or system.

AM1704K Working Principle

The AM1704K switch consists of three primary components: a rotary shaft, a pair of stationary contacts, and a spring-loaded ‘snap action’ mechanism that looks like a miniature lever. The rotary shaft determines the direction of rotation and the lever is used to change the switch’s setting. When the shaft is rotated, its teeth interact with the teeth on the ‘snap action’ lever and cause it to move. This motion causes one of the stationary contacts to touch the other contact and create a circuit, thus completing the electrical circuit.

The ‘snap action’ lever also acts as a safety feature. It is designed so that when the rotary shaft reaches its preset limit, the lever will snap back and open the circuit, preventing further rotation of the shaft and protecting the machine or system from damage. This design also allows the switch to be used in a momentary or latching mode depending upon the user’s needs.

The AM1704K is also highly durable and reliable. It is constructed with a die cast housing and features a stainless steel spring-loaded rotor that ensures smooth and reliable operation. The switch is rated for up to 10,000 cycles, ensuring a long-lasting and dependable product that can be used in a variety of applications.

Conclusion

The AM1704K snap action, limit switch is an efficient and reliable device that can be applied in many industries, medical and commercial applications. Its rotary shaft, ‘snap action’ lever, and stationary contact design allows it to be used in momentary or latching modes and its durable construction ensures a long-lasting and dependable product. It is a versatile and invaluable component to have in many industrial and commercial projects.
