A level switch senses liquid levels in tanks using a plastic tube filled with air. They come in various sizes and designs, from simple to complex, and can be adjustable or two-stage. They can also detect wet/dry conditions and liquid-liquid interfaces. A level switch, also commonly referred to as a float switch, is a device […]
A solenoid switch uses a small amount of energy to create a magnetic field that connects to a larger power source. It has a metal coil, rod, and connectors, and is commonly found in automobiles. When energized, the magnetic field pushes the rod to create a loop and allow power flow. Solenoid switches are reliable […]
A thermostatic switch is a control that operates by measuring the temperature emitted by the device it controls, automatically switching it off when the desired temperature is reached. It is commonly used in electric ovens, home thermostats, and to protect electrical devices. The switch must be programmed with two separate temperatures to function properly. A […]
A centrifugal switch uses centrifugal force to open or close electrical contacts when a machine reaches a set rotational speed. It consists of spring-loaded weights and switch plates, and is commonly used in starter circuit breakers and split-phase electric motors. A centrifugal switch is a device designed to open or close a series of electrical […]
A mercury switch is a glass tube containing liquid mercury and two electrodes that connect when tilted past a certain angle, allowing electricity to flow. However, mercury is dangerous, so many manufacturers are replacing them. They are used in thermostats, car lights, and even motion-activated bombs. Broken switches are toxic waste and should only be […]
A deadman switch is a safety feature that shuts down a machine if the operator experiences a problem or becomes incapacitated. It requires operator input and can be found on a variety of machines. It can also make machinery difficult to steal. The deadman switch is a safety feature built into many machines that works […]
A disconnector is a switch that cuts off power to electrical circuits for safety during maintenance or emergencies. It is used in power distribution, commercial activities, and homes. Lockout systems are recommended, and switches must be rated for their application. A disconnector is a switch that has the ability to cut off power to an […]
Railway switches allow trains to change tracks. They are activated by hand or electronically and most positions are blocked. A reflective marker indicates the direction of the switch and engineers are taught to verify it. Speed limits are reduced in switch areas and damaged switches are repaired or replaced. A railway switch is a device […]
Rocker switches are one-piece switches commonly used as light switches and in other applications. They are easy to use and can be wired in a multi-way switch system. When repairing or replacing, cut off power to the circuit. A rocker switch is a one-piece switch that swings back and forth in response to pressure to […]
Switching devices are mechanical, electrical, pneumatic or hydraulic devices that open or close an electrical circuit. They can be as simple as a bedside lamp switch or as complex as heavy-duty industrial starters. They are also used in data switching and found in common appliances. A switching device is any mechanical, electrical, pneumatic or hydraulic […]
Winter tires are necessary for drivers in regions with harsh winters, as all-season tires do not provide enough traction on snow and ice. Snow tires are designed for cold weather and perform better in extreme conditions. Upgrading to a complete set of winter tires is recommended for safety on the road. Drivers who live in […]
An air compressor switch, also known as a pressure switch, turns off the compressor when the tank pressure reaches a certain point. It is rated in PSI and prevents dangerous explosions. The switch is similar to those used for regulating water pumps. An air compressor switch is also known as a pressure switch and is […]
A compressor pressure switch regulates air compressor operation by starting it when pressure drops below a set point and stopping it when it reaches a maximum value. It is essential for industries heavily reliant on compressed air and can be mounted on the compressor or in an accessible location. The switch consists of a pressure […]
The reed switch was invented in 1936 by WB Elwood at Bell Telephone Laboratories. It is a magnetically operated switch used in burglar alarms, electrical circuit controls, and the communications industry. It consists of ferrous metal contacts or springy metal reeds inside a sealed glass tube. The switch is activated by a magnet or magnetic […]
Duodenal switch surgeons specialize in a weight loss surgery that combines stomach size reduction with intestinal redirection to reduce food intake and absorption. The procedure carries a high risk of nutritional deficiencies, but is less likely to cause dumping syndrome and stomach ulcers. Prospective patients should seek experienced surgeons and investigate whether the surgery is […]
A transfer switch changes the power source of a load, with automatic switches having logic controls. A power backup system requires a transfer switch, which can be open or closed transition. Soft loading prevents overloading, and a generator transfer switch switches between generator and commercial power. A transfer switch, which can be an automatic or […]
Choosing the right car seat for your child is crucial for safety and legal compliance. Different types of car seats are available, including rear-facing, forward-facing, and booster seats. It is important to follow age, weight, and height restrictions and check local laws before traveling. Improper use can result in fines and criminal charges. Seat belts […]
A pull switch is a convenient and safe way to turn electrical power on or off for lights and appliances, especially in damp areas. It can be a string or pull chain switch, and can be used in public safety situations. Three-way switches allow the same light to be turned on/off at both ends of […]
A rotary switch is a switch that is operated by twisting. It consists of a rotor and one or more decks, allowing for a wide range of settings. Analog switches were common until the mid-1970s, with push buttons, toggle switches, and dials being the three basic styles. Rotary switches were commonly found on telephones and […]
Switch clusters come in various designs such as push/pull, momentary, or toggle versions. They break or bridge an electrical circuit and can be connected to positive electrical current or the ground side. Components include contacts, terminals, and a switching mechanism. Switches range from simple on/off types to rheostat-type switches with a wide range of settings. […]
