A 1VA20 snap action, limit switch is an electrical switch device used to detect the presence or absence of an object, or move of the object. It can be used in a wide range of applications from low-level currents such as those used in home electronics to high-powered applications such as industrial and automotive control systems. This type of switch is widely used for applications such as control and automation, power monitoring, error prevention, as well as in security and safety equipment. The following is an overview of the 1VA20 snap action, limit switch and its working principle.

The 1VA20 snap action switch is a two-piece on/off switch, which consists of a housing and a contact. The housing typically contains an actuator, a mechanical spring, a plunger and a bias plate. The actuator is the input, and a force on the actuator causes the plunger to compress against the bias plate, thus activating the contacts. The spring inside the housing then returns the plunger and bias plate to the original position.

One of the main advantages of the 1VA20 snap action switch is its high durability and reliability. The materials used are usually resistant to extreme temperature, humidity and shock, making the switch reliable in many different environments and applications. Furthermore, the switch is self-cleaning, meaning that it will automatically clean the contacts when it is actuated. This ensures that the switch will remain reliable over time.

In terms of operation, the 1VA20 snap action switch is activated by a physical contact. This contact can be either manual or automatic, depending on the application. For example, manual activation would involve you physically pushing a button which activates the switch. Whereas an automatic activation could involve a machine moving a slider which activates the switch. Both these scenarios rely on the physical actuation of the 1VA20 switch to trigger the required action.

In terms of working principle, the 1VA20 snap action switch works based on the basic principles of limit switch technology. A limit switch is a type of control device which uses an electrical circuit to detect the motion or position of a device. When the switch is actuated, the current flow will be altered in the circuit, thus enabling the device to detect either the presence or absence of an object or the move of the object.

Apart from its high reliability, the 1VA20 snap action, limit switch also has a long lifetime and is designed to be low-maintenance. It does not require lubrication and does not produce any sparks when actuated. Furthermore, the switch is designed to reject false triggers, and can be used in high-power applications. As such, the switch is suitable for a variety of uses, from home electronics to industrial and automotive control systems.

In conclusion, the 1VA20 snap action, limit switch is a highly reliable and durable electrical switching device that is suitable for many different applications. It consists of two pieces, a housing and contact, which are activated by physical contact, and uses basic limit switch technology to detect objects or their movement. Furthermore, the switch is designed to reject false triggers, is low-maintenance, and has a long warranty. As such, it is an ideal choice for many applications, such as control and automation, power monitoring, error prevention, as well as in security and safety equipment.
