5HM1

Snap action, limit switches are electromechanical switches that open or close a circuit when a certain mode or level is reached. They are typically used to detect the location of a movable contact, to set a limit on the travel of a contactor, or to control the speed or direction of movement. 5HM1 is an important switch model within this type of switch. This article will explain the application field and working principle of 5HM1 switch.5HM1 switch is specially designed for low voltage AC or DC circuits. It can work normally in the environment of −25℃-45℃. The on-state resistance is at most 25mΩ and its electrical durability is over 500000 cycles. It also has two different working states: NO/NC which means normal open/normal close. Therefore, it can be widely used in many different industrial fields such as home appliances, electronic equipment, power tools, air conditioning and commercial control. As for its working principle, 5HM1 switch is composed by permanent magnet, lever, spring and contact points. The 5HM1 switch is mounted in a lever operating in a cylindrical opening. The lever is magnetized so that it is attracted toward the permanent magnet. When the lever is not subject to external force, it is held in the “OFF” position by the magnet. When external force is applied to the lever, the lever is displaced from the operating cylinder and the spring closes the contact points. The magnetic force is too small to pull the lever back to the operating cylinder, thus the 5HM1 switch is maintained in the “ON” position. When the external force is removed, the lever is pulled back by the magnet to its original position and the contact points are open.In conclusion, 5HM1 is a great snap action, limit switches with broad applications. Its simple mechanism allows a large variety of forms and switching forces to be made. It has proven to be the most recommendable snap action, limit switch product in the market due to its optimal stability, cost and performance.
