There are many poles to choose for the use of the switch. Different gears are selected according to different usage conditions. The details are below.
The switching switch is generally composed of three parts: metal shell, reed plastic support and switch blade. The insulating base of the switch sheet is generally glass silk plate, and there are two rows of cut-in fixed contacts pressed on it. There are small grooves on the plastic support with corresponding fixed occlusive sliding reeds in the groove. The metal shell fixes the reed plastic support with the switch blade. When switching the switch, the plastic bracket drives the spring to slide on the fixed contacts on the switching plate. The positioning beads and springs make the switching action positioning accurate, and can ensure that the switch does not dislocate under certain vibration conditions.
A toggle switch is a component that controls the switch's opening or disconnection by toggling a plastic handle to change the contact point.
The common gears of the switch are: 1 pole 2 bit, 1 pole 3 bit, 2 pole 2 bit, 2 pole 3 bit, 4 pole 3 bit, 4 pole 4 bit, 10 pole 3 bit, 4 Pole 10 bit, etc. Among them, multi-pole multi-bit switches larger than 3 poles are mainly used for band conversion. Some band switches can have as many as a dozen bits and can change more than a dozen switch gears.
Digging switches are widely used in this field due to their small size and light weight, such as:
Rotary screen of digital photo frame, gravity induction of mobile phone, anti-theft equipment, intelligent system. But the switch has its shortcomings, there are angle limitations, there must be a certain angle in order to make the switch trigger. Therefore, there are still some mercury switches, the demand for the switch has been on the rise, and the market prospects are promising.
