Forward Reverse Switch

A forward-reverse switch is a device commonly used in electric motors and machinery to control the direction of rotation. It allows the user to easily switch between forward and reverse motion. Here’s a breakdown of its key features and components:

1. Switch Lever or Button: The central control mechanism, which can be toggled to either the "Forward" or "Reverse" position. Some switches may have a neutral or off position.

2. Wiring: The internal wiring of the switch changes the polarity of the motor or alters the connection to the power source, reversing the direction of current flow.

3. Contact Points: These are the conductive elements that establish connections when the switch is toggled. The contacts for forward and reverse positions are separated to ensure the correct flow of current.

4. Mechanical Interlock: Many forward-reverse switches have an interlock mechanism to prevent the switch from being accidentally moved to both directions simultaneously, which could cause damage to the motor.

5. Enclosure: Typically, the switch is housed in a protective case to prevent damage and ensure safety from electrical hazards.

Application: Forward-reverse switches are used in various devices such as electric drills, conveyor systems, hoists, and in industrial equipment where changing motor direction is required.
