D2HW-A201H is an example of Snap Action, Limit Switches. This type of limit switch is typically seen in controlling operations, whether electrical or mechanical, such as door locks, parking ticket machines, and so on.
The D2HW-A201H features a protective cover with strain relief, a roller plunger actuator, and a double-throw contact system. It is designed to provide an accurate and reliable switching action and be resistant to shock, vibration and wear.
The D2HW-A201H is most commonly used for controlling circuit and mechanical applications, such as door locks, vending machines, etc.
The working of the D2HW-A201H can be divided into two parts: the snap action and the limit switch.
Snap Action
The snap action of the switch is made possible by the roller-plunger actuator. This plunger is contained in a small cylinder and can be pushed in or pulled out. When the plunger is pushed in, the roller at the end makes contact with a tiny spring, which causes the switch to close.
When the plunger is pulled out, the rollers lose contact with the spring, and so the switch opens. This is the basic principle behind the snap action of the switch.
Limit Switch
A limit switch is used to limit the range of motion of the actuator. In the D2HW-A201H, there is a double-throw contact system which includes two sets of contacts. The first set of contacts is normally open, while the second set is normally closed.
When the plunger is pushed in, the first set of contacts closes and the second set opens, thus limiting the range of motion of the plunger. In this way, the switch can be used to ensure that the limit of movement of the actuator is not exceeded.
The D2HW-A201H is a reliable and accurate limit switch with a snap action. It is used in many applications, including door locks, vending machines, and other controlling operations. It is designed to be resistant to shock, vibration, and wear, thus ensuring it lasts a long time and is reliable.
