S7B/U Application Field and Working Principle
Toggle switches are a form of electrical devices that allow the user to manually turn electrical power on and off. These switches are commonly referred to as toggle switches due to their push-button form factor and two-position capabilities. In essence, toggle switches are devices that enable power in the area where it’s used. Toggle switches are implemented in many different industries and applications, from home lighting and entertainment systems to industrial automation controllers.
S7B/U Toggle Switches
S7B/U switches are specific types of toggle switches that are designed to provide reliable performances in many hazardous and hostile working environments. These switches are used for safety applications and are certified to UL and CSA standards. These toggle switches feature an IP65 rating and are dust-tight and waterproof, providing robustness and reliable performance. They also have a high electrical strength and short-circuit strength to ensure that they remain operational even when subjected to high overloads.
The S7B/U toggle switches features a height of 24.6 millimeters, width of 16.2 millimeters, offering ease of installation and use. They feature a single pole, double throw, 3-position configuration, with one momentary (On/Off) position and one latching (On/Off) position, as well as a neutral position. These switches also have a operating temperature range of -30 to +85 degree Celsius, making it suitable for various applications in different settings.
Working Principle
The S7B/U toggle switches operate by a toggle lever contacts. The user will pull the lever down to its ‘On’ position to turn the power on. When the lever is released, its return spring will pull it back to the ‘Off’ position, thus turning the power off. The toggle lever contacts enable the switch to operate in both momentary and latching positions, depending on the requirements of the application.
This toggle switch also features a stainless steel base and a housing that is made from polycarbonate and reinforced with fibreglass. The enclosure is also flame resistant, making it suitable for use in hazardous environments. The lever is made from mild steel and has a rating of IP65. These elements ensure that the switch can withstand the hostile environment it is meant to operate in, thus providing reliable performance.
The S7B/U toggle switches have a wide variety of applications, from lighting and HVAC systems to industrial controllers, energy metering and hand-held instruments. The switch offers reliable performance, long-term reliability and ease of installation and use.
