Types of Magnetic Switches

MagneLink is proud to offer multiple types of magnetic switches that work in a range of industries and applications. Each type of magnetic switch features unique components that allow them to accommodate certain currents and voltage levels for different uses and functions. MagneLink’s magnetic switch selection includes Reed switches, Hall switches, Triac, Transistor, and Coded switches. Each unique design makes the switches suitable for specific types of applications.

Reed switches

Reed switches use a simple magnetic reed contact to open or close an electrical circuit. These are often referred to as ‘dry contact’ switches. They can operate on either alternating current (AC) or direct current (DC) voltage circuits.

Reed switches are widely used due to their ability to switch both AC and DC loads. Reed switches are often used to detect whether doors are open or closed. Because they can switch either AC or DC loads, repair technicians often prefer them to stock on repair trucks so they can minimize their inventory while having switches readily available for on-site repair work in a variety of electrical circuits.

MagneLink’s Reed switches can be found in places like: CNC equipment, power transmission, recycling equipment, actuators that may be used in automated equipment in factories, car washes, and material handling. Some other applications may include: automotive safety, such as seatbelt buckles and in sensors used to detect collisions, or in security systems. Reed switches are also common in home appliances, such as refrigerators, which rely on sensors to detect when the door is closed or open to turn off/on the light, or in top-loading washing machines, which stop the washing cycle upon the door opening. Reed switches are also commonly found in Internet of Things devices, electronics, communications equipment, and automation controls.

Hall effect switches

Hall switches use solid state devices that can better withstand mechanical shock when compared to magnetic reed switches. Hall Effect switches operate on DC voltage circuits, and require power to the sensor in order to operate properly. Their ideal application is for small electrical loads, but MagneLink can incorporate additional circuitry to accommodate larger loads as needed.

MagneLink’s Hall switches are used in applications such as: elevators, and actuators used on a variety of larger machines for automation controls in industrial settings or CNC equipment.  Hall switches, operate on low DC voltages and currents, making them ideal for use in household white goods – such as washing machines and dryers – that have high-speed sensors. They also can be used in DC transformers, and in automotive settings to control fuel gauges.

Triac switches

Triac switches are designed for use in AC voltage circuits with heavy inductive loads (i.e. Relays, Starter coils, etc.). Their ability to switch high voltages and large currents make them ideal for use in a wide range of environments.

Triac switches are commonly used in devices for general AC flow control, especially circuits switching heavier inductive loads where current spikes can occur.  MagneLink Triac switches are used in: compactor and baler equipment, as sensors in water parks, brewing equipment, material handling in industries like plastics manufacturing, and hydraulic equipment. Some other applications may include household applications. They can be used in devices for controlling lights––such as light switches and dimmers––as well as in fans and small motors.

Transistor switches

Transistor switches are designed for use in DC voltage circuits with heavy inductive loads (i.e. Relays, Starter coils, etc.). Their ability to switch high voltages and large currents make them ideal for use in a wide range of environments.

MagneLink’s Transistor switches can be found in: waste recycling and disposal equipment, power distribution and transmission systems, manufacturing equipment used for food processing, textiles, paper industries, etc.  Our transistor switches operate in DC voltage circuits and are prime candidates when switching heavy duty inductive loads that may have current spikes occur.

Coded switches

Coded switches are designed for applications requiring an additional level of security making the switch even less defeatable.  A special coded magnet is used to activate these switches.  Coded switches are available that operate in either AC voltage circuits or DC voltage circuits with heavy inductive loads.  They do require additional DC power to operate properly.

Coded switches are most beneficial to circuits requiring an added layer of security.  They are useful in applications where it is desirable to make a switch even less defeatable than a standard magnetic switch.  These are typically found in more critical safety switch applications.  MagneLink’s coded switches are available in designs operating in AC voltage switching or DC voltage switching, depending on what is required.
