Types and features of toggle switches

　toggle switchIt is a manual control switch, mainly used for on-off control of AC and DC power supply circuits. It has the characteristics of small size and convenient operation, and is often used in electronic equipment.

In manual operation, the toggle switch can be divided into two levels. First, pull the trigger to the middle with your hand until the trigger is vertical. At this time, the apex of the single-pole slider gradually approaches the middle until the middle position, and further compresses the compression spring. After the trigger passes through the vertical position, the unipolar slider moves quickly in the other direction under the pressure of the compression spring, and drives the trigger to rotate quickly. At this time, the moving contact is rapidly separated from the fixed contact pin on one side and rapidly connected to the fixed contact pin on the other side. This is the second stage. At this time, the separation speed of the contacts is related to the pressure of the compression spring and the friction force between the moving parts, and the speed is very high. According to the test, the time from contact disconnection to reconnection is only about milliseconds, and the average speed reaches the old millimeter second. This speed is many times faster than the manual pull speed or the motorized test pull speed.

　　classification of toggle switch:

1. Bipolar single toggle switch. The switch turns on and off the phase line and the N line at the same time to control a branch, so it is a bipolar single-link toggle switch. The contact is in the form of 3PDT, which is mostly used for multimedia speakers and audio.

2. Vertical installation right angle toggle switch. The vertical installation of the terminal is at right angles to the terminal pin, so the right angle toggle switch is installed vertically. Its contacts are made of gold-plated material for high reliability. For anti-theft devices and alarm systems.

3. Splash-proof knob toggle switch. The panel is equipped with "O" type sealing ring, and the knob handle is spherical, so it is a splash-proof knob handle knob switch. The terminals are in-line, and the bottom of the terminals is sealed with epoxy resin. Strong corrosion resistance, suitable for auto parts.

4. Install the right angle toggle switch horizontally. Compared with the vertical switch, it just changes the direction to horizontal, so it is a horizontal right-angle toggle switch. The contact is double-pole double-throw, and the bottom of the terminal is sealed with epoxy resin. More for computer peripheral equipment.

5. Standard surface mount unthreaded toggle switch. The terminal adopts the standard installation form, and its sleeve is not threaded, which is called the standard surface sticker without threaded toggle switch. The contact is single-pole double-throw, and the electrical life is up to 55000 times. More for medical equipment.

toggle switchIt's an electrical switch. Open or close the circuit by moving the lever back and forth. There are two kinds of toggle switches on the market: self-locking and reset. The self-locking toggle switch will change the position of the shift lever when activated and will remain in this position until activated again. The reset toggle switch is activated only when someone operates the switch. The toggle switch is simple to operate and can be used in commercial and household appliances, usually as a light-controlled switch. Some toggle switches also have flip covers to prevent false switches.
