Toggle switches are electrical switches that are dismantled into more than one physical positions and connection positions. They are generally used to isolate transmission in power systems and industrial control systems. And the655H series two-position toggle switches are one kind of conventional toggle switches.

Introduction of 655H toggle switches

The 655H two-position toggle switches are mainly composed of molded dust-proof body, knob, terminals, seal components and conductor parts. The dust-proof body can effectively protect the inside parts and material from dust, damage, and make sure it is easy to install, interconnect, and adjust. This series toggle switches are formed by a plastic body and silver plating copper terminals. It can be applied to various kinds of physical environment, such a s extreme temperatures, humidity, dust, and corrosive atmosphere, meeting the needs of different applications. Besides, every raw materials, production process and testing items meet the standard of UL and CUL.

655H application field and working principle

The 655H two-position toggle switches have a broad selection of operating power rating from 1A to 12A (120V AC), 1.3A to 15A (240V AC), 0.4A to 4A (125 V DC), 0.4A to 5A (250V DC), and is suitable for automobile, ships, aviation and electrical installations. Besides, it also has a compact structure with a circular actuator and a wide variety of knob designs and colors for selection. With the characteristics of light force and sensitive action, it is convenient for operators to use. The most important part of655H series two-position toggle switches is the contact mechanism. It has two or three movable contacts and a return spring. Due to the action of the return spring, the movable contact can always reset to one fixed contact. When the switch is turned on, the movable contact z and z′ will close to each other, thus the current flows and the circuit is turned on. When the switch is turned off, the movable contacts z and z′ separate from each other to stop the current or break the circuit.

Conclusion

The 655H series two-position toggle switches are reliable, safe, and environmental friendly. In order to ensure its quality and performance, each toggle switch must pass through rigorous tests and these tests are conducted strictly according to the testing process. With its broad selection, light force and sensitive action, the 655H toggle switches can fit the most applications. And the UL and CUL certification is an evidence of its excellent quality. With the 655H toggle switches, you can expect superior performance and satisfaction of your needs.
