What is the specification of toggle switch?

The toggle switch is to switch the circuit by pressing the switch handle to open or disconnect the circuit. Dial switches are generally single-pole 2-bit, single-pole 3-bit, two-pole 2-bit, two-pole 3-bit, etc. Toggle switches are generally used in low-voltage circuits and have the characteristics of flexible slider action and stable and reliable performance. Dial switches mainly include: various instruments/meter equipment, various electric toys, fax machines, audio equipment, medical equipment, beauty equipment, and other electronic products. Table 9-10 lists the main characteristic parameters and shape structure of some toggle switches.
