What is Toggle switch:
Toggle switch is a manual control switch, which is mainly used for on-off control of AC and DC power supply circuits, but it can also be used in circuits of thousands of Hz or up to 1 MHz. It has the characteristics of small volume and convenient operation. It is a common switch in electronic equipment.
Types of electromechanical switch of FBelec
There are two and three operation positions. The three position switch can have the position of one side not positioned, etc. At the same time, there are many kinds of connecting circuits. There are many kinds of button handles for button switches, such as metal conical button handle, plastic conical button handle, fluorescent button handle, plastic sleeve button handle, spherical button handle, flat rod button handle, lock rod button handle, waveform button handle, paddle button handle, etc. The lock rod type button handle is suitable for dangerous operation occasions. There is also a "lifting and unlocking" button handle, which is added with a spring, and the end of the screw pipe mouth is provided with a milling groove. The operator must first lift the button handle and then push it to another position to ensure safe work.
Action principle of Heavy Duty Rocker Toggle
During manual operation, the switch action can be divided into two stages. The first stage is to pull the handle towards the middle by hand until the vertical position of the handle. At this time, the tip of the single knife slider also gradually moves closer to the middle until the middle position, and the compression spring is further compressed. After the handle passes the vertical position, the single knife slider moves rapidly in the other direction under the pressure of the compression spring and drives the handle to turn quickly. At this time, the moving contact piece is quickly separated from the fixed contact foot on one side and quickly connected with the fixed contact foot on the other side. This is the second stage. At this time, the separation speed of the contact is related to 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 contact disengagement to reconnection is only about milliseconds, and the average speed is several millimeters and seconds. This speed is many times faster than manual trigger speed or mobile test trigger speed.
Precautions for electrical switch
(1). First, select the appropriate type of switch and connector according to the service conditions and functions
(2). A certain margin shall be reserved for the rated voltage and current of DPST Marine Toggle switch and connectors
(3). In order to ensure reliable contact, a certain margin shall be reserved for the number of wires of switch contacts and connectors for parallel use or standby
(4). Try to select connectors with positioning to avoid faults caused by wrong insertion
(5). The wiring and welding of the contact shall be reliable. In order to prevent wire breakage and short circuit, the welding place shall be protected by a sleeve
Life test of mechanical devices toggle switch
Since the test life of the switch is obviously related to the plate moving speed during the test, in order to measure a correct service life, there should be a correct test pulling speed. Since the test life shall reflect the service life during manual operation, the pulling speed of this mobile test shall be consistent with that of manual operation. That is, the value of manual pulling speed shall be tested.
Using the millisecond meter to test the on-off time, the pulling time of the button switch handle from one limit position to another can be measured. The pulling speed can be calculated from the pulling time and distance. This speed is the average speed over the entire pulling distance. According to the actual test, the manual pulling speed is different when the operator is not in charge, and the same operator is also different at noon every time, with an average of about. Between a millimeter and a second.
Although there is no domestic standard for SPST Toggle Switch test pulling speed, there are still foreign standards for reference. In the general specification for sealed Sub-miniature toggle switches of the U.S. military specification formulated on August, it is stipulated that the button switch shall be driven by a motorized driving part at the speed of one minute, one British and state second. In the test conditions of the above hunger sub switch standard, while specifying the test times per minute, the test pulling speed is specified, and its value is one inch second, i.e. millimeter second. On the one hand, it shows that it is necessary to specify a test speed, and the test speed value specified in this standard is relatively close to the manual pulling speed obtained from our test, and the difference may be caused by the difference of each prisoner's manual operation speed. It is reasonable that this manual operation pulling speed is the driving speed of mobile test. For the sake of unity, the range can also be reduced to one millimeter second.
