Common Metal Push Button Switch types and application fields (2)
Today we continue to talk about Common Metal Push Button Switch types and application fields.
3. Knob gear switch, which is to control the circuit by rotating the knob, generally has two and three gears; when the knob is in the initial position, the circuit is powered off and the switch indicator light goes out; after the knob is rotated to the first gear, the first gear is The corresponding circuit is energized and the switch indicator light is on; after the knob is rotated to the second gear, the circuit corresponding to the second gear is energized and the switch indicator light is on; the knob gear switch is often used to adjust the speed, brightness, temperature, etc. scenarios, such as fan speed, washing machine speed, air conditioner temperature, etc.
4. The lever gear switch is to control the circuit by turning the lever. There are generally two and three gears. The lever is in the initial position. At this time, the circuit is powered off and the switch indicator light goes out. Move the lever to the first gear. After that, the circuit corresponding to the first gear is energized and the switch indicator light is on; after the lever is moved to the second gear, the circuit corresponding to the second gear is energized and the switch indicator light is on; the lever gear switch is often used when it is necessary to switch Scenarios of opening, closing, and changing states, such as turning on a microphone, electric guitar tone switch, ship and airplane instrument panel, etc.;
5. A locked switch means that the switch is equipped with a lock cylinder inside. You need to insert the matching key and rotate it to unlock it for circuit control. When initially locked, the circuit is powered off and the switch indicator light goes out; insert the matching key and rotate to unlock, and the circuit is energized at this time. , the switch indicator light lights up; locking switches are generally used in scenarios with high authority levels and high safety that require power on and off, such as water gates, electric gates, and switches for dangerous operating facilities, etc.
