The 175578-1 application field and working principle fall into the category of Terminals - Housings, Boots. This particular product is a dead-front tubular switch which is designed for use in high-voltage commercial and industrial applications that require reliable electrical operation and safety. The switch is constructed with a pressure actuated contact and a steel case with a plastic interior lining, making it highly durable and resistant to corrosion and wear and tear.

Such a switch is typically available in three size configurations, each with a rated voltage of 9,000V and a current rating of up to 200 Amps. It\'s excellent electrical and mechanical characteristics make it suitable for use in a variety of applications including immersion well pumps, single phase construction and industrial motor control, tank level control, appliance control, indoor and outdoor lighting, line/load disconnects, and a multitude of other specialty applications.

To operate the switch, a user must first move the handle into the “off” position, which moves the plunger into the open position. When the plunger is in the open position, the contacts require no force to maintain, and do not close until engaged by a plunger. At this point, the plunger must be pushed in to “close” the contacts, allowing the current to flow and the motor to start. Once the motor is running, the plunger must be moved to the “on” position in order to maintain the circuit.

When the motor has completed its cycle, the plunger must be returned to its initial open position. This establishes an open circuit and prevents the current from flowing through the switch. The plunger should never be left in the “on” position during equipment shutdown or the switch will become locked in the closed-contact position, thus preventing any further operation. All of this is accomplished using a simple lever-activated plunger mechanism, protected against the elements by the steel case and plastic interior.

In addition to its mechanical characteristics, the 175578-1 is also designed with convenient electrical connections, allowing for installation and removal with minimal effort. The pressure actuated contacts are insulated to prevent arcing and keep the electrical system secure. The switch also offers optional accessories including an indicator light and a manual reset option for use in hazardous areas, as well as a locking device for use in harsh environments.

The 175578-1 belongs to the category of Terminals - Housings, Boots and provides users with a reliable and durable electrical switch for a variety of applications. With its pressure actuated contact, steel case with plastic interior lining, and convenient electrical connections, the switch makes it easy to install, safe to use, and ensures reliable operation in a variety of environments.
