Switch

Types of Switches

There are numerous types of switch 1 devices. A selection of the most common ones is as follows:

• Toggle switch

  A toggle switch is a mechanical device with a lever that, when moved, opens or closes a circuit. The most common type is the SPST (Single Pole Single Throw) toggle switch, which has two positions: ON and OFF. SPDT (Single Pole Double Throw) toggle switches with three terminals that allow connection to one of two circuits simultaneously are also available.

• Push button switch

  A push button switch is a momentary or maintained contact device. Momentary contact switches (NO) are off until pressed, whereas maintained contact switches (NC) have an open or closed circuit until pressed. They are widely used in various applications, from simple user interfaces to complex industrial control systems.

• Rotary switch

  A rotary switch is a circular dial with multiple positions for selecting different functions or settings. It can be a single-pole (SP) or multi-pole (MP) switch. The most commonly used rotary switch is the 12-position one, which connects to 12 different circuits, making it ideal for applications requiring multiple settings or modes.

• Slide switch

  A slide switch is a mechanical component with a sliding actuator that opens or closes a circuit. The most common type is the SPDT (Single Pole Double Throw) slide switch, which has three terminals that connect to one of two circuits. Slide switches are often used in portable devices, such as battery-powered products, to control power and conserve energy.

• Rockerswitch

  A rocker switch is a two-position switch with an actuator that rocks or tilts to open or close a circuit. The most commonly used rocker switch is the SPST (Single Pole Single Throw) type, which has ON and OFF positions. SPDT (Single Pole Double Throw) rocker switches with three terminals are also available and are used in various applications, from household electrical devices to automotive lighting systems.

Specification and Maintenance of Switch

The specification of any switch is determined by its use in different applications. Here are the general specifications that are considered when selecting a switch for an application.

• Current Rating

  The switches have a current rating that is the maximum current that can flow through the switch without causing any damage to the switch. If the current flowing through the switch exceeds the current rating of the switch, it will cause overheating and damage to the switch.

• Voltage Rating

  The voltage rating of a switch is the maximum circuit voltage that the switch can handle. Just like the current rating, the voltage across the switch should not exceed the voltage rating of the switch.

• Switching Capacity

  The switching capacity is the current and voltage the switch can handle during an operation. The switching capacity is important during the design of a circuit because it determines the component that can be used within a circuit.

• Contact Configuration

  The contact configuration of a switch is the arrangement of the switch's contacts. This includes the number of contacts and the type of operation, such as normally open or normally closed. Different applications require different contact configurations.

• Mechanical Life

  This is the number of operations a switch can perform before it starts to wear out. Switches with higher mechanical life are more suitable for applications with frequent switching operations.

• Electrical Life

  Electrical life is the number of operations a switch can perform under its electrical rating. The electrical life of a switch is always less than the mechanical life due to factors such as arc and contact wear.

• Operating Force

  The operating force is the amount of force required to operate the switch. The operating force of a switch should be compatible with its application. For instance, a switch used in a handheld device should have a lower operating force than a switch used in a power tool.

• Insulation Resistance

  Insulation resistance is the measure of the resistance offered by the switch against the flow of current through its body. A good switch should have a high insulation resistance to prevent short circuit and damage to the switch.

• Dielectric Strength

  Dielectric strength is the maximum voltage that can be applied to the switch without causing breakdown of its insulating material. The dielectric strength of a switch is important for applications involving high voltage.

• Environmental Considerations

  Environmental consideration is a specification that determines the switch's ability to withstand harsh environmental conditions. These harsh conditions include temperature, humidity, dust, and moisture. A good switch should be able to withstand these environmental conditions without affecting its performance.

Below are some tips for maintaining switches to ensure their reliable performance.

• Switches should be inspected periodically to detect any sign of damage, wear, or contamination. The inspection should be done when the switch is in an OFF position.
• Switches should be cleaned regularly to remove dust, moisture, and contaminants. The cleaning should only be done using a soft cloth or brush.
• Switches should not be operated with excessive force. This can cause physical damage to the switch.
• Switches should not be used in applications beyond their electrical and mechanical specifications.
• Worn-out switches should be replaced immediately to prevent failure in the circuit.
