Introduction

The 7211MDW3QE is a double-pole, double-throw (“DPDT”) type of toggle switch, a component with two sets of contacts for making and breaking two separate circuits by a manual pulling of the lever (or by depressing a button). It is sometimes referred to as an “on-off” switch with six terminals, allowing it to be connected in two separate circuits at once.

Application Field

The 7211MDW3QE is primarily used as an alternative to traditional switches and relays in applications requiring high-switching frequencies, such as automotive,industrial, and medical equipment where robust, reliable activation/deactivation is required. It is suitable for a wide range of applications ranging from low-voltage DC batteries to high-voltage AC. Toggle switches may be used for a variety of purposes, including light switches, power switches, appliance switches, and automotive switches.

Working Principle

The 7211MDW3QE is a mechanical electromechanical switch. When the lever is manually lifted (or a button is depressed), the contacts inside the switch open and close at different times to make/ break the circuit. Since the contacts are physically opened and closed by electromechanical means, there is no surge or breaker to protect the circuit from over-voltage conditions. In other words, if too much voltage is present in the circuit, then the contacts in the switch may become permanently damaged.

The switch is designed to work without fail, so that it may be used repeatedly without any issues. When used correctly, with proper voltage sensitivity, the 7211MDW3QE Toggle Switch should provide reliable and trouble-free performance.

Conclusion

The 7211MDW3QE Toggle Switch is a reliable, robust and cost-effective switch used in various applications. With its two contact sets, it can be used to make and break two circuits at the same time. Its mechanical electromechanical design ensures reliable performance, even when used at high voltage levels. It is suitable for a wide range of applications, including automotive, industrial, and medical products.
