Toggle Switches

Toggle switches are the most commonly found types of switches and are used in a wide variety of applications ranging from the simple on/off switching of domestic light fittings to much more complicated industrial control systems. One example of a toggle switch is the 7215P3YAV2QE, which is a double-pole, double-throw, non-captive toggle switch with a positive detent action.

Application Field

The 7215P3YAV2QE is commonly used for applications such as:

• Lighting control
• Signal selection
• Power supply connections
• Control circuits
• Sub-circuits

In added to being used as an on/off switch, this toggle switch is also often used as a selector switch, allowing the user to select between two or more different electrical connections.

Working Principle

The 7215P3YAV2QE is a center-off, double-pole, double-throw (DPDT) toggle switch, with a positive detent action, meaning that it will stay in each position until it is forcibly moved to the other position. The two poles of the toggle switch are wired in such a way that when the switch is in the center position, both poles are disconnected from their respective connection terminals. When the toggle switch is moved to either the up or down position, both poles of the switch will be connected to their respective connection terminals.

The 7215P3YAV2QE is a non-captive toggle switch, meaning that it can be freely moved between the two positions without the need to hold it in place. It utilizes a positive detent action to ensure that the switch stays firmly in place when it is moved to either the up or down position. This detent action is facilitated by a spring inside the toggle switch that provides resistance when the switch is moved, ensuring that it stays in place.

Conclusion

In conclusion, the 7215P3YAV2QE is a double-pole, double-throw, non-captive toggle switch with a positive detent action. It is commonly used for applications such as lighting control, signal selection, power supply connections, control circuits and sub-circuits. It utilizes a center-off, double-pole, double-throw operation, with a positive detent action that prevents the switch from moving out of position.
