UnionwellRecommended Unionwell SPDT roller lever micro switch

SPDT roller lever micro switch is also called snap action switch. The configuration circuit is single pole double throw. The top lever is a hinge lever with a roller at the end. The roller switch can realize sliding mode switch. The stroke increases with the distance away from the fulcrum, while the load decreases. It is suitable for operating environments with small operating force or large stroke.

Unionwell SPDT roller lever Micro Switches Application Case

AGV handling robot

The anti-collision stop device at the front/rear end of the AGV handling robot is generally equipped with two of our G9 series SPDT roller micro switches. When the AGV encounters an obstacle or a person during driving, the external force passes through a series of transmission mechanisms in the anti-collision device and finally triggers the micro switch to generate a signal, transmitting the information of the obstacle or person encountered to the control system. The control system issues a stop command to stop the AGV.

Application of multifunctional travel limiter for tower crane

The multifunctional travel limiter of the tower crane is composed of a speed gear, a memory cam and the corresponding G5 series roller micro switch of our company. The displacement signal that can be synchronized with the controlled mechanism is connected to the input shaft of the limiter after the speed change of the external hanging wheel, and is converted into the angular displacement signal of the output shaft through the speed change of the reducer to realize the three-coordinate control and limit protection function.

FAQ

What is the main function of a SPDT micro switch?

SPDT micro switches are used to switch between two circuits. They have one input and two outputs and are often used in applications where you need to select between two states or paths.

What is the difference between SPDT micro switches and other types of switches?

Compared with SPST (single pole single throw) switches, SPDT switches offer more connection options and can switch between two outputs, but DPDT limit micro switches are recommended for applications with more complex circuits. For details, see the article 《What Is The Difference Between SPDT And DPDT Switch?》

What are the common applications of SPDT micro switches?

SPDT micro switches are widely used in home appliances, LED light control, audio equipment input selection and other fields to achieve function switching or mode selection.

What factors should be considered when selecting an SPDT micro switch?

When selecting, factors such as the switch's rated current and voltage, mechanical life, operating force, mounting method, and compatibility with the application circuit should be considered.

What other types of micro switches are there ?

There are four types of circuit micro switches, with the following characteristics:

SPST (single pole single throw): one input, one output, for simple on/off control.

SPDT (single pole double throw): one input, two outputs, can switch between two circuit paths.

DPST (double pole single throw): two independent inputs, each with a corresponding output, can control two independent circuits at the same time.

DPDT (double pole double throw): two independent inputs, each with two outputs, can switch between two sets of circuit paths.
