Toggle switches, also known as toggle switches and lever switches, are the most commonly used manual switches
and are widely used in electronic instruments, meters and electrical equipment. Toggle switch is a manual control
switch, which is mainly used for on-off control of AC and DC power circuits, and can also be used in circuits of several kilohertz or up to 1 MHz.

1. Types
There are two types of operation positions: two-position and three-position. The three-position switch can also have a position that is not positioned on one side.
At the same time, there are many types of connection circuits. There are many types of toggle switch handles, such as metal cone handle, plastic cone handle,
fluorescent button handle, plastic sleeve button handle, spherical button handle, flat lever handle, locking lever handle, wave button handle, paddle button handle etc.
Lock lever handle is suitable for hazardous operation. There is also a “lift-to-unlock” button handle with a spring and a milled groove at the end of the solenoid.
The operator must first lift the button handle, and then push it to another position to ensure safe work.
2. Action principle
When the toggle switch is manually operated, the switch action principle can be divided into two stages.
1. The first stage of the action principle of the toggle switch
Move the trigger to the center with your hand until the trigger is in the vertical position. At this time, the pointed top of the single-pole slider also gradually moves
toward the middle until it reaches the middle position, and the compression spring is further compressed.
2. The second stage of the action principle of the toggle switch
After the trigger passes the vertical position, the single-pole slider moves rapidly in the other direction under the pressure of the compression spring, and drives the trigger to
turn rapidly. The contact pins are connected quickly. At this time, the separation speed of the contacts is related to factors such as the pressure of the compression spring and the friction
between the moving parts, and the speed is very high. According to the test, the time from the disengagement of the contact to the reconnection is only about milliseconds, and the average
speed reaches the old millimeter-second. This speed is many times faster than manual pull speeds or motorized test pull speeds.
Through the introduction of the above content, everyone has a clearer understanding of the knowledge of the toggle switch.
The toggle switch is very necessary in life, and it is also used in some households, so you can correctly understand its working principle and understand It is very important to look at its type.
