Snap action, limit switches are electro mechanical devices used for controlling and/or determining the state of a system, machine, or process. The 7AS12 is a special type of snap action limit switch that can be used in a variety of applications.

The 7AS12 is a compact yet robust switch that uses a simple, reliable design to offer reliable and precise switching action. The mechanical design is similar to a standard limit switch, but with a much higher switching speed. The 7AS12 features an internal spring assembly that provides an instantaneous switching action when the contact points are activated. This fast switching speed makes the 7AS12 ideal for applications that require precise actuation and response times.

The 7AS12 is also available with a range of optional accessories, including tamper proof housing and external mounting brackets, making it ideal for a variety of applications including safety and security devices, remote controls, robotics, car starters, and industrial automation.

The 7AS12 snap action, limit switch is a reliable and cost-effective device for a range of applications. Its robust design ensures reliable switch operation and a long operational life. Additionally, its fast switching action and wide range of accessories make it suitable for a range of special applications including high-speed and precision response times.

The 7AS12 has an actuation force of 10 Newton, with an operational life of 1 million cycles, and a maximum voltage rating of 250V. It is available with a number of contact ratings, including 3A @ 250V ac, 5A @ 30V dc, and 5A @ 125V ac. The housing of the 7AS12 is UL Approved to UL 508-C standard, while the contact blocks are compliant with UL 1059-C standard.

The 7AS12 works on the simple principle of a short travel switch that triggers a contact-opening or contact-closing event. The travel range of the switch is determined by the internal spring assembly, and the response depends on the balance of the force applied on the plunger and the spring pressure on the plunger housing.

When an external force-causing movement is applied to the plunger, the plunger travels a pre-determined distance, determined by the adjustment of the internal spring assembly, and the contacts open or close. The external force can come from a button, lever, or other actuator, and can be generated by mechanical or electrical means.

When the plunger is released and the external force is removed, the spring assembly returns the plunger to its original position. This action either reverses the contact state or maintains the same contact state, depending on the design of the switch.

The advantages of the 7AS12 switch are numerous. It is a low-cost, reliable, and field-proven device that is suitable for many different applications and systems. Additionally, the 7AS12 is UL approved and has a wide range of contact and voltage ratings available.

In conclusion, the 7AS12 snap action, limit switch is a reliable device suitable for a multitude of applications requiring precision operation or high-speed response times. Its robust design and reliable switching action make it an ideal choice for a range of applications.
