Toggle switch refers to a component that controls the on or off of the switch by toggling the plastic handle to change the contact point. It turns on or off the circuit by pulling the switch handle, so as to achieve the purpose of switching the circuit. The commonly used types of toggle switches are unipolar double position, unipolar three position, bipolar double position and bipolar three position. It is generally used in low-voltage circuits and has the characteristics of flexible sliding block action and stable and reliable performance. Toggle switches are widely used in: various instruments / instrument equipment, various electric toys, fax machines, audio equipment, medical equipment, beauty equipment and other electronic products. Below, pinzan electronics introduces the performance and specifications of the pull switch.
