8th January 2025
By Team Elcom

Using a high-quality electrical switch in your machinery is for the best as it ensures the safety and efficiency of the equipment concerned. These switches control the flow of electricity by completing or breaking an electric circuit.    However, when the same switch that is so crucial goes out of commission, the problem can be more […]

Types of Electromechanical Switches

Rotary
Switches
Rotary switches offer multiple positions arranged in a circular path. These switches incorporate a mechanism that controls the flow by rotating through a series of predefined positions. Initiated by a start or stop command, the rotational movement of the switch adjusts the operational intensity and speed, thereby promotes controlled functionality. They are actuated by turning a knob or shaft. The number of positions can vary widely, depending on the application. Standard actuators include push-on knobs, finger wheels, and keylocks. Renowned for their reliability and durability, rotary switches are frequently used in fan regulators, coolers, and other equipment requiring multiple settings.
Rocker
Switches
Rocker switches, characterized by their distinctive rocking motion, are often used for direct power on/off control. Available in illuminated and non-illuminated versions, they come in various sizes and actuator styles to suit diverse design aesthetics. Rocker switches find applications in various devices, from consumer electronics to industrial equipment.
Keylock
Switches
Keylock switches require a specific key to operate. They are rotary switches with an added security layer. This feature makes them ideal for equipment where unauthorized access is a concern, such as industrial machinery, elevators, and security systems.
Push
Button
Switches
These switches are activated by pressing a button. They can be momentary (returns to original position when released) or latching (remains depressed until manually reset). Push buttons come in various sizes, colours, and actuation forces to accommodate user preferences and operating environments. They are commonly used in control panels, appliances, and electronic devices.
Micro
Switches
Also known as snap-action switches, micro switches are compact devices that provide rapid contact transfer. Various mechanisms, including levers, push buttons, and rollers actuate them. Microswitches are prized for their precision and responsiveness, establishing them as a perfect fit for applications requiring accurate and fast switching, such as automotive systems and industrial automation.
Thumbwheel
Switches
Thumbwheel switches feature a series of wheels with numerical or alphabetical characters. Users can input data or select options by rotating the wheels. They are commonly found in test equipment, data entry devices, and industrial control systems.

Applications of Electromechanical Switches

Railway
Switches control signaling, lighting, and power systems in trains and railway infrastructure.
Telecom
They are used in telephone exchanges, network equipment, and communication devices.
Consumer
Electronics
From power switches on televisions to volume controls on audio systems, electromechanical switches are ubiquitous in consumer products.
Medical
Electronics
These switches find applications in medical equipment, such as patient beds, infusion pumps, and diagnostic devices.
Industrial
Electronics
Electromechanical switches are essential components in industrial control systems, automation equipment, and machinery.
