First of all, the switch with a toggle on the side of their own, from left to right in order for the toggle switch for the first, second and third pins, the center pin must be connected to the pin. The method of connection can be the first pin on the left and the center pin connection, or the third pin on the right and the center pin connected to use.
Expanded information:
Toggle switches are widely used in electrical appliances and other equipment, and are used to connect and disconnect circuits by toggling the actuator (toggle key or switch handle). Reliable and other characteristics, widely used in electrical appliances, machinery, communications, digital audio and video, building automation, electronic products.
The two-stage three-legged toggle switch is a commonly used one, its three legs, the center is the public **** end, toggle to the left, connected to the left two pins, toggle to the right, connected to the right two pins.
Toggle switch pins and the connection of the outside world line, most of the tin soldering technology, but often cause false soldering and other quality accidents, large factories are generally used in mechanized, automated operations rather than direct operation of the workers, the problem of false soldering also still exists, so cited riveting technology to connect instead of the original solder connection.
But when this has a new pin structure of the fluctuation switch into the circuit, in order to achieve mechanized, automated operation of the precise control, in order to improve the higher standard of the circuit connection requirements, the need to accurately identify the three pins of the two-position three-legged toggle switch.
