Toggle switch is a manual control switch, mainly used for AC/DC power circuit on/off control, generally can also be used in several kilohertz or up to 1 MHZ circuit. It has the characteristics of small size and easy operation. It is a commonly used switch in electronic equipment.
In manual operation, the switch action can be divided into two stages. The first stage is to pull the handle towards the center by hand until it is in a vertical position. At this time, the tip of the single-blade slider is gradually closer to the middle, until the middle position, and further compression. After the lever passes the vertical position, the single blade slider moves quickly to the other direction under the pressure of the spring, and drives the lever to turn quickly. At this time, the moving contact plate is rapidly separated from the fixed contact foot on one side and connected with the fixed contact foot on the other side. This is the second stage. At this time, the separation speed of contact and pressure dang pressure size and friction between moving parts and other factors, the speed is very high.
According to the test, the time from contact disengagement to re-connection is only about milliseconds, with an average speed of old millimeters seconds. This speed is faster than manual pull speed or maneuvering test
It's many times faster.
The operation position of the toggle switch has two or three positions, there can also be one or two position, pull the knob handle to leave the position, release the hand instantly rebound.
At the same time, there are many connection circuit types, so as button handles of toggle switch, like lock rod type knob handle, metal conical knob handle, plastic conical knob handle, fluorescent knob handle, plastic sleeve knob handle, spherical knob handle, flat knob handle, lock rod knob handle, wave knob handle, paddle knob handle, etc.
Lock rod type knob handle is suitable for dangerous operation occasions, and "promote unlock" type knob handle, which has a spring, screw mouth end milling groove, the operator must first lift the knob handle, and then push to another position, in order to ensure safe work.
Notes on the use of toggle switch
1, First of all, according to the use conditions and functions to choose the right type of switch and connector.
2. The rated voltage and current of the switch connector should have a certain allowance.
3. In order to contact reliable, switch contact and connector line number to have a certain amount of allowance, in order to parallel use or spare.
4. As far as possible to choose with positioning plug-in, so as not to insert wrong and cause failure.
5. Contact wiring and welding is reliable, in order to prevent broken lines and short road, welding should be protected by casing.
