Toggle Switches are a fundamental part of most common electronic systems, and the 7201MDW3QE model is a great example. It is a single pole double throw switch, featuring an etched black plastic base, heavy duty screw terminals and a gold plated switch contact. This makes it ideal for use in a range of applications and industries, from consumer electronics to industrial automation.

Application Field

The 7201MDW3QE Toggle Switch is particularly well-suited for use in automotive, aerospace and other hazardous environments. The switch features a plastic base, which provides excellent corrosion-resistance in harsh conditions. The switch contact is also gold-plated, providing increased corrosion resistance, making it a great choice for exposed applications. In addition, the switch is designed to handle up to 1amp at 120VAC, making it suitable for a wide range of automotive and industrial applications, such as power switches, circuit cut-offs and actuators.

The 7201MDW3QE also has uses outside of the automotive and industrial field. It is well-suited to consumer electronics applications, such as audio amplifier switches, or even providing on/off operations in simple circuits. Due to its ease of use and reliable performance, it is a popular switch for hobbyists and DIYers alike.

Working Principle

The 7201MDW3QE Toggle Switch is a single-pole double-throw switch, meaning it has a single input and two outputs. When the switch is engaged, the input is connected to one of the two outputs. When the switch is flipped, the input is connected to the other output, thus “throwing” the switch. This type of switch is typically found in applications where a device needs to be switched on and off with a single circuit.

The 7201MDW3QE features a screw terminal connection, which is used to easily connect and disconnect the switch from a circuit. The switch terminals are connected to two pairs of contact blades, which are gold-plated for added corrosion protection. The blades are connected to two separate outputs, which are then connected to either a normally open (NO) or normally closed (NC) output. When the switch is flipped, the blades make contact with the corresponding blades, thus completing the circuit and “throwing” the switch.

The 7201MDW3QE is a reliable and durable switch, making it a great choice for a wide range of applications. Its plastic base and gold-plated contacts provide it with excellent corrosion protection, while its screw terminal connection provides an easy way to connect and disconnect the switch from a circuit. These features, along with its wide range of uses, make it a great choice for anyone looking for a reliable toggle switch.
