Snap action, limit switches are widely used in industry and in automation and control systems. They serve to open and close electrical circuits, both on a direct current (DC) and alternating current (AC) basis. One such switch which is popular for its precision, value for money and extended service life is the V15H22-CZ300-K (hereafter referred to as the V15 switch).

The V15 switch is a limit switch, meaning it has an actuating element which will only move an electrical circuit in one particular direction. This is done by means of a plunger – when the plunger is pushed in, the electrical contact is closed, at least until the plunger is released. When the plunger is released, the contact opens again. The plunger also acts in conjunction with a set of micro-cast lever arms which provide for more precise contact closure.

The V15 switch is constructed of best quality alloy materials and has a long life expectancy. When it is set up correctly, using the correct control voltage or current, it will offer a reliable performance. It is capable of withstanding high shocks, tremors and vibration due to its solid construction and the fact that it is mechanically linked to the plunger.

Due to its excellent properties and features, the V15 switch finds numerous applications, some of which are in petroleum plants, industrial machinery and electronic production lines. It can be used to cut off current supply in an emergency, open and close relays, indicate machine process completion and detect the presence of a machine component. In combination with a timer it can be used for furnace control, fire detection and water valve operation. The V15 switch is also commonly used in production control systems, to detect overloading and machine shutdown, where safety is of paramount importance.

The working principle of the switch is quite simple and can be understood more clearly by referring to a diagram. The plunger is pushed in and out by an external force, such as a vibration, movement or action from a machine component, and describes an arcuate path, while the lever arms remain at a fixed position. As the plunger moves in and out, the lever arms move along the side of the plunger and open and close the electrical contact, accordingly. This mechanism ensures that the contact is opened and closed at the correct time and by the correct amount.

The V15 switch is reliable and relatively inexpensive. Its long life expectancy and wide range of applicable uses makes it ideal for any industrial application. As it is easy to install, replace and maintain even by personnel with minimal knowledge of electrical engineering, it has become a popular choice for many.
