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.
In modern industrial automation, industrial push button switches are widely used in various equipment and systems as an important control element. They not only provide a simple and effective way of operation, but also play an important role in safety and reliability. This article will explore the definition, types and applications of industrial push button switches in […]
Factors of choosing normally closed contacts for emergency stop buttonsThe emergency stop button contacts on electrical equipment are either normally open contacts or normally closed contacts. Therefore, people often ask whether the emergency stop button uses a normally closed contact or whether it uses a normally open contact. The factors are as follows:1. From the moment […]
Waterproof system of metal push button switchWhen it comes to waterproof push button switches, the most important thing is quality, because waterproof push button switches are switches that can be operated even with wet hands.The safe waterproof system of the waterproof button switch:1. It is used to isolate the power supply and disconnect the high-voltage maintenance […]
