Toggle switches are activated by a handle angled in one of two or more positions and forth to open or close an electrical circuit. The usual light button used in household wiring is an example of a toggle switch. Toggle switches can be found in different dimensions or sizes, from miniature PCB mount up to power rated panel placed switches.

  • The toggle switch is a kind of electrical switch that is recognized by the presence of a handle or lever that makes it possible to control the flow of electric current/signal from a power supply to a tool or within a device. It is a hinged switch that can undertake either of two placements i.e., ON or OFF. It is utilized to change to switch between two conditions in a circuit.
  • A toggle switch is physically triggered (or pushed up or down) by a mechanical knob, lever, or shaking mechanism. These are typically used as light control switches.
  • Most of these switches come with two or more knob positions which are in the varieties of SPDT, SPST, DPST, and DPDT switch. These are used for controlling high currents (nearly 10 A) and also can be used for switching small currents.
  • These are offered in different ratings, sizes, and styles and are used for different types of applications. The ON condition can be any of their level positions, however, by convention, the downward is the closed or ON position.

Being very easy in operation, the toggle switch can be applied in a number of different applications, both for industrial and also in household purposes.

Types of Toggle Switch

There are two basic categories: maintained contact and momentary contact. Maintained-contact toggle switches and momentary-contact toggle switches differ in terms of switch configuration.

Maintained-contact toggle switches are listed below.

  1. ON and OFF functions which works like light switches.
  2. Toggle switches having a three-position, halfway point that may or may not perform an OFF function.

Momentary-contact toggle switches include the following.

  1. Momentary ON/OFF describes contacts that interrupt the circuit when the toggle switch is in the normal, open (NO) and Closed (YES) positions respectfully.
  2. To describes alternate ON/OFF, where the first actuation transforms the toggle switch ON and the second actuation transforms the toggle switch OFF.
  3. Three-position momentary center-NEUTRAL toggle switches have a center position that can perform an OFF or NEUTRAL function.

There are numerous formations for pole and throw toggle switches.

  • Single pole single throw (SPST) toggle switches open or closes the connection of a single conductor in a single branch circuit. This switch type naturally has two terminals and is referred to as a single-pole switch.
  • Single pole double throw (SPDT) toggle switches close or opens the connection of a single conductor with either of two other single conductors. These switches usually have three terminals and are generally used in pairs.
  • Double pole single throw (DPST) toggle switches close or opens the connection of two circuit conductors in a single branch circuit. They usually have four terminals.
  • Double pole double throw (DPDT) toggle switches close or opens the connection of two conductors to two isolated circuits. They usually have six terminals are available in both momentary and maintained contact versions.

Wire connecting of the Toggle Switches to Your Devices

The action in this area is meant to be taken as a basic guideline for a straightforward on-off (single pole, single throw or SPST) toggle switch.

  1. Review the instructions supplied with Switch: To set up a toggle switch is simple. First, read the installation handbook and determine electrical arrangements, where you want to connect the switch.
  2. Disconnect the live wire in your device: To operate the switch as an on-off state, you’ll need to wire your toggle switch to the device’s power supply. Cut the device’s power supply cable in a place that best permits routing either or both ends of the wire to the switch.
  3. Include a pigtail if required:  A pigtail is a short sized braided cable connecting a fixed part to a moving part in an electrical device. It can be attached to a cord that isn’t moderately long enough to reach your toggle switch as a sort of “extender.”
  4. Reconnect the live wire to the toggle switch: At this stage, you’ve made a break in the device’s supply cord, you’ll need to add your toggle switch in the middle of the break to ensure that it can regulate the flow of electricity through the path.
  5. Test your switch: When your toggle switch is wired properly, reconnect the power supply, and test the function of the toggle switch. If it works as planned.

Congratulations! You’ve successfully installed a toggle switch.

How to Install Toggle Switches in your car

A toggle switch is so named because it is a switch with a long handle, or toggle, to control it. A very functional device, toggle switches are found in everything from simple circuits to heavy equipment. Generally, you can install toggle switches in automobiles or other motorized vehicles by flowing some tips.

Tip 1: Drill a hole in the location where you wish to place the switch. Verify the area before you start to confirm that you won’t drill into any wiring.

Tip 2: Press the switch wire into the hole and join it to the power supply wire of the vehicle using a terminal connector.

Tip 3: Attach the switch to the hole using the nut that came with the switch. A loose switch can cause wiring problems.

Tip 4: Connect the power cord of the switch to the accessory you plan to toggle, such as the headlamp. Find the wire of the device and linked the two wires using a two-cable port. Finally, connect the ground wire of the switch to the negative side of the battery of your vehicle.
