What is 7201L40HZQE?

7201L40HZQE is a SPST toggle switch, with a zinc plated housing and a UL94V-2 switch cover. It has an operating voltage that varies between 125V and 250V, an operating current between 16 A and 120 A, a contact resistance of 19 mΩ max, and an insulation resistance between 100 MΩ and 500 MΩ. The rated load for this switch is 40 A at 40 Hz and the dielectric strength is between 600 VAC and 1000 VAC.

Application Field

7201L40HZQE toggle switch is suitable for use in general purpose applications such as automotive, appliances and consumer electronics. Due to its low cost, high durability and versatility, it is frequently used as a replacement for SPDT or DPDT switches in various circuits. Some common applications that use this switch are motors and pumps, HVAC systems, power distribution and related systems.

Working Principle

7201L40HZQE works like a common toggle switch. It can switch between two states, in the Off position, it closes the circuit and in the On position, it opens the circuit. The switch is operated by turning the rocker lever up or down to activate the switch, which then either connects or disconnects the electrical connection. The switch contacts are made of brass and are covered with a zinc-plated metal cover to prevent electrical arcing and protect the user from accidental electric shocks.

The toggle switch is sealed from outside elements, dirt and dust that could corrode or otherwise damage the contacts, making the switch reliable and durable for many years of use. Also, the switch comes with an adjustable torque setting that helps to ensure smooth and reliable operation when used in a variety of applications.

Conclusion

7201L40HZQE toggle switch is a commonly used model that is suitable for a variety of general-purpose applications. It is cost-effective, reliable and durable. Its working principle is fairly simple and straightforward; it opens and closes an electrical circuit when the rocker lever is turned up or down. It is also sealed from outside elements, making it an ideal switch for use in automotive, home appliances and other general-purpose applications.
