This creation is about a metal button switch structure, especially a button switch made of contacts and pins with a large area, which can be used to control the on or off current when the overall volume of the button switch is unchanged. Larger equipment is required. Therefore, this creation can be used in a toll machine on a ship, a factory, or a general parking lot, with a wide range of applications.

According to the press, electronic equipment has become a necessity in modern people's lives, from the most commonly used household appliances in life, to the production equipment of factories, various vehicles such as cars, ships or airplanes, or roadside seen Nowadays, these items are not only driven by mechanical structure, but many electronic components have been added to provide richer functions, such as automatic production, automatic driving and other functions. The development of electronic equipment is quite diverse. No matter what, there is a great opportunity to connect with electronic equipment.

The use of electronic equipment represents the need for power consumption, so in order to reduce the power consumption when the electronic equipment is not in use, a switch is usually installed in the electronic equipment to provide users with the ability to turn the power on or off by themselves; There are many types of operation methods, such as rocker switches, rocker switches, or push button switches. Although the operation methods are different, they are functionally used to control the switches of the device. In terms of a button switch, there is usually only one button. The user presses the button to switch the current state of the device. The originally opened state will be turned off, and the originally closed state will be turned on.
