Siemens 3SU1150-7BE88-1QA0 Coordinate Switch, 22mm Metal Shiny Black, 4-Position Latching Control Switch Original Brand New

Overview

The Siemens 3SU1150-7BE88-1QA0 Coordinate Switch is a premium-quality industrial control component designed to deliver precise and reliable switching operations in demanding environments. Manufactured by Siemens, a global leader in automation and electrical engineering, this switch is part of the trusted 3SU1 series, known for durability, performance, and modern industrial design.

This coordinate switch features a 22 mm mounting diameter, making it compatible with standard control panels and operator consoles. Its round, shiny black metal finish not only enhances aesthetics but also provides excellent resistance to wear, corrosion, and mechanical stress. With four latching switch positions, the device allows stable and secure selection without the need for continuous operator pressure.

Equipped with mechanical interlocking and a defined O (neutral) position, the Siemens 3SU1150-7BE88-1QA0 ensures safe and controlled operation. The switch includes a holder and four Normally Open (NO) contacts, all connected via reliable screw terminals, ensuring easy installation and secure electrical connections.

Benefit

• Enhanced Durability: The metal shiny construction provides superior resistance to mechanical wear and environmental stressors, ensuring a long service life.

• Precision Control: With four distinct switching positions, operators can manage complex movements with a single interface point.

• Maximum Safety: The integrated mechanical interlocking in the zero (O) position ensures that the switch cannot be engaged without intentional operator action.

• Ease of Installation: Supplied as a complete unit with a holder and four contact blocks (1 NO per position), utilizing standard screw terminals for secure wiring.

• Global Compliance: Siemens SIRIUS ACT components meet international standards (IEC, UL, CSA), making them suitable for global export and operation.

Function

The primary function of the 3SU1150-7BE88-1QA0 is to act as a directional master switch.

1. Latching Operation: Unlike momentary switches that spring back, this latching model holds its position in any of the four directions (Up, Down, Left, Right).

2. Directional Logic: Each of the four positions corresponds to one of the four included 1 NO contact blocks, allowing for independent signaling for different machine functions.

3. Mechanical Locking: The “Interlocking in O” feature requires the operator to perform a specific mechanical release action before moving the lever, preventing unintended machine startups.
