Difference between Lock and Momentary switches? Push Button Switch, Slide Switch
2021 / 05 / 18
Lock switches and momentary switches operate in different ways and therefore suit different applications. What is the difference between Lock and Waterproof Push Button Momentary Switch? Lock Switches Latching switches are switched on by the user and then remain on until switched off again. They do not require continuous compression from the user. Latching switches can be found in the home and are used for things like light switches, central heating switches or on stereos. Momentary switches Momentary switches require continuous compression. They will switch on when the user compresses the switch and will remain on only for as long as there is pressure on the switch. Once the pressure is removed they will switch off. For example; a door buzzer or an electric drill. The momentary switches are used within the medical industry on the hand or foot control for hospital beds. The patient can move the bed to the desired position but they must keep their finger on the button for the bed to move. We also provide momentary switches for [press to talk" applications. Operators of telephones use the switch to answer the phone and the line will remain open as long as the switch is pressed down.

Rotary switches are switches operated by rotationes. These are often chosen when more than 2 positions are needed, such as a three-speed fan or a radio with multiple frequencies of reception or "channels". Automotive Rotary Switches consist of a spindle or rotor that has a contact arm or "spoke" which projects from its surface like a cam. It has an array of terminals, arranged in a circle around the rotor, each of which serves as a contact for the "spoke" through which any one of a number of different electrical circuits can be connected to the rotor. Rotary Switch Types are layered to allow the use of multiple poles; each layer is equivalent to one pole. Usually such a switch has a detent mechanism so it "clicks" from one active position to another rather than stalls in an intermediate position. Thus Automotive Rotary Switches

What does SPST, SPDT, DPST, and DPDT mean? SP and DP mean to single pole and double poles, ST and DT refer to single throw and double throws. Pole means to the number of circuits controlled by the switch: SP switches control only one electrical circuit. DP switches control two independent circuits (and act like two identical switches that are mechanically linked). Do not confuse `pole` with `terminal`. The DPST switch, for example, has four terminals, but it is a DP, not a 4P switch. Throw refers to the extreme position of the actuator: ST switches close a circuit at only one position. The other position of the handle is Off. DT switches close a circuit in the Up position, as well as the Down position (On-On). DT switch can also have a center position (frequently On-Off-On). Single pole/throw and double pole/throw switches are by far the most common switches, but triple and quadruple configurations are also available. They are commonly denoted 3PST, 3PDT, 4PDT, etc.

Introduction and operating principle of Micro Switches
2020 / 01 / 07
Introduction and operating principle of Micro Switches A Micro Limit Switch is a contact mechanism with a small contact interval and a fast-acting mechanism. It uses a specified stroke and a predetermined force to perform the switching operation. It is covered with a housing. There is a switch with a driving rod on the outside because the contact distance It is relatively small, so it is called a micro switch, also called a sensitive switch. The electrical text symbol is: SM. working principle External mechanical force acts on the action through transmission elements (pins, buttons, levers, rollers, etc.) Waterproof Micro Switches On the reed, an instantaneous action occurs when the action reed is displaced to a critical point, so that the movable contact and the fixed contact at the end of the action reed are quickly turned on or off. When the acting force on the transmission element is removed, the action reed generates a reverse action force. When the reverse travel of the transmission element reaches the action critical point of the reed, the reverse action is instantaneously completed. The micro switch has a small contact distance, a short action stroke, a small pressing force, and a fast on-off. The speed of the moving contact has nothing to do with the speed of the transmission element. 2 types edit Micro Switches Types, with hundreds or thousands of internal structures. There are ordinary type, small size, and ultra-small size according to volume. According to protection performance, there are waterproof, dustproof, and explosion-proof types. Single type, double type, multi-connection type. There is also a strong disconnect micro switch (when the switch's reed does not work, external force can also open the switch); according to the breaking capacity, there are ordinary type, DC type, micro current type, high current type. According to the use environment, there are ordinary type, high temperature type (250 ℃), ultra high temperature cer

Classification and Detailed Introduction of Tact Switches
2019 / 12 / 25
Classification and Detailed Introduction of Tact Switches The switches are mainly divided into the following types, Tact Switches, Toggle Switches, Key Switches, direct key switches, power switches, Rocker Switches, etc., Each type is described in detail below. What is a tact switch? Tact switch It is an electronic switch, which can be turned on by lightly pressing the switch button when in use. When the hand is released, the switch is turned off. The internal structure of the switch is turned on and off by the force of a metal spring. The tact switch is composed of: insert, base, shrapnel, button, and cover. The waterproof tact switch adds a layer of polyimide film on the shrapnel. Tactile switches are widely used in home appliances due to their low contact resistance, crisp touch feel, complete height specifications, etc., such as: audio and video products, digital products, remote controls, communications products, household appliances, Security products, toys, computer products, fitness equipment, medical equipment, banknote detectors, laser pen buttons, etc. But the touch switch also has its shortcomings. Frequent pressing will make the metal shrapnel fatigue and lose elasticity and fail. Therefore, most of the buttons of electrical appliances are now directly replaced by conductive rubber or pot switch hardware springs, such as computer keyboards, TV remote controls, etc. Regarding the pin connection of the five-pin tact switch: two pins are in a group, the four corners are for more stable
The characteristics of Rotary Switches
2019 / 12 / 20
The characteristics of Rotary Switches Rotary Potentiometer Switch can be used to replace the traditional rotary pulse generators of the analog resistance potentiometer. These rotary switches are usually used in the human-machine interface of the front panel of the instrument and the audio-visual control board. The rotary switches use orthogonal optical encoders instead of analog potentiometers These purely digital devices, these rotary switches are similar in appearance to traditional or resistive potentiometers, but the internal structure of these rotary switches is completely digital and uses optical technology. Similar to traditional incremental encoder products, there are two orthogonal output signals (channel A and channel B), which can be directly connected to the encoder processing chip. Rotary switch Rotary Switch Types is a switch that controls the main contact to open and close by rotating the handle. There are also two structural forms of rotary switches, which are a unipolar unit structure and a multi-pole multi-position structure. Single-pole unit rotary switches are often used together with rotary potentiometers in applications, while multi-pole and multi-position rotary switches are mostly used for switching the working state circuit.
