Miniature Micro Switch In Elevator
How Do Elevators Work
Elevators or a lift is the vertical transport vehicle that efficiently moves people or goods between the flows of a building. Electric motors power the elevators that either drive traction.
Cables and counterweight systems pump hydraulic fluid to raise a cylindrical piston. Elisha Otis, a mechanic in a mattress factory in Yonkers, New York, pioneered the technology of elevator safety and paved the way for the modern passenger elevator.
G6 Miniature Micro Switch In Elevator Door Safety Touch Panel Protection Device
There are movable safety touch panels on the edge of the elevator car door. When people close the door, if the safety touch panel is in contact with passengers or obstacles, the link-rod will connect the safety touch panel device by the miniature micro switch. And the micro switch is installed on the car door. At last, reopen the door to avoid elevator accidents.
Here Are Two G6 Series Miniature Micro Switches
The G6 series micro switch is small in size and has a device with high reliability and service life. The load capacity of the segment is as high as 10 (2) A 1/4HP.
The G6 series micro switch parameters are as shown in the following table:

People prefer to apply G6 miniature microswitches in automotive control, home-appliance control, etc.
There are two significant elevator designs in everyday use today.
- Hydraulic elevators
- Dropped elevators
This Section Will See How Roped Elevators Work As The Most Popular Elevates.
The elevator car is raised and lowered by traction steel ropes in dropped elevators rather than pushed from below. The strings are attached to the elevator car and looped around achieve. Achieve is just a pull-up with a groove around the circumference. The sheave grips the hoist ropes, so when you rotate the sheave, the strings move to the sheave, which is connected to an electric motor. When the motor turns one way, the sheave raises the elevator. When they turn another way, the sheep lower the elevator gearless.
In elevators, the motor rotates sheaves directly in geared elevators. The motor turns a gear train that circles the sheep. Typically the engine and the control system are housed in a machine room above the elevator shaft. The ropes lift the car. They are also connected to a counterweight that hangs on the sheep’s other.
Elevator Balance Principle
The counterweight weighs about the same as the car filled to 40% capacity. in other words, when the vehicle is 40% full, the compensation and car have perfectly balanced. The purpose of this balance is to conserve energy with equal loads on each side of the sheep. It only takes a little force to tip the balance one way or the other. The motor only has to overcome friction. The weight on the other side does most of the work; to put it another way, the balance maintains near-constant energy in the system. Using up the potential energy in the elevator car builds up the potential energy in the weight. The same thing happens in Reverse when the elevator goes up.
The system is just like a seesaw with an equally heavy kid on each, and the elevator car and the counterweight ride on guide rail along the sides of the elevator shaft. The rails keep the car and counterweight from swaying back and forth. They also work with a safety system to stop the vehicle in an emergency; roped elevators are more versatile than hydraulic elevators.
The Suggestions For Elevator Primary Micro Switch
To start with, we need to understand the circuit layout and the ranking requirement for the micro switch. For instance, in many European nations, the voltage is 220VAC, so we need to use a switch that can get to 220V at a minimum. To see if they are appropriate, we use a 250VAC switch usually. The electric current coincides with things.
Secondly, what circuit code do you need? Are they usually Closed or generally open up? Which relies on your engineer’s style.
Third, which operate you need? You may need to consider whether they are waterproof or non-waterproof, as I know many of them are non-waterproof.
Ultimately, the accreditation. Suppose a manufacturing facility may require the certificates for the micro switch. For example, Europe requires ENEC, America and Oceania need UL, Asia needs CQC, and so forth.
