Snap Action, Limit Switches: GLDC01K8B application field and working principle

A typical snap-action switch is the GLDC01K8B, which may be found in electrical and electronic equipment from all around the world. This important element in machinery has multiple functions and application fields, all of which can be better understood, knowing its working principle.

The GLDC01K8B is the product model of the Panasonic company. It stands for a snap-action switch which belongs to the zone of contacts normally open (NO). The abbreviation stands for “standard heavy-duty, double layer, break-before-make”. It is based on a structure of precession-wound bobbin which contains a momentary stationary contact, while the other contact is mounted on a plunger. The place where these contacts meet is the so-called breakover point, where a short circuit can be created. By turning the knob, the stationary contact is caused to make limited movement, thus allowing for a perfect connection.

The snap-action switch uses a straightforward operating principle, which is mainly due to the design of the parts mentioned above. The knob is connected to the bobbin via a shaft and the plunger. As the knob is turned, it pushes the bobbin, which in turn moves the plunger. This motion causes the plunger to make a direct contact with the stationary contact, thus creating a perfect connection. By pressing the knob at the breakover point, the switch has to make a break before it can make a connexion again at the breakpoint. This is the single most important advantage of the GLDC01K8B, as it ensures the durability and reliability of the machine.

The GLDC01K8B has a wide array of applications, mainly due to its user-friendly design and its ability to be used in large groups. It is often used in automation applications, such as in circuit boards or when controlling motors. It can also be found in larger machines, such as vehicles and large-scale industrial equipment. Thanks to its relatively low cost and its easy-to-understand working principle, it is a preferred choice for many engineers.

In conclusion, the GLDC01K8B is a reliable snapshot switch with a user-friendly design and great functionality. Its mechanical functions are based on the design of a bobbin, plunger and stationary contact, while the applications range from automotive to industrial and from electrical to circuit board-related. It is an affordable and efficient solution for any engineer.
