S-TEC Module Intermediate Switch

• Introducing the S-TEC International range of switches and sockets, meticulously engineered to be "The Safe Option!" for all residential and commercial electrical installations.
• This comprehensive collection combines modern aesthetics with robust, high-quality construction to deliver unparalleled safety, reliability, and convenience.
• Every product in the S-TEC range is crafted from durable, high-quality materials and is backed by a 2-year warranty, ensuring peace of mind. 
• This specific product, the S-TEC Module Intermediate Switch (STI-1160M), is the specialist component for advanced lighting control within the S-TEC modular system.
• It is a high-quality, 16 Amp intermediate switch mechanism designed specifically to allow control of a single lighting circuit from three or more different locations.
• When used between two 2-way switches, it provides the ultimate convenience for large rooms, long hallways, and multi-level staircases.

Features

• Modular Design: Functions as a core component of the S-TEC modular grid system, allowing for flexible and customized switch plate configurations.
• Intermediate Switching Action: A specialized 4-terminal switch that, when placed between two 2-way switches, reverses the polarity of the travellers, allowing for control from a third (or fourth, fifth, etc.) location.
• Heavy-Duty 16 Amp Rating: A robust electrical rating that comfortably handles standard lighting loads, ensuring reliability and a high safety margin.
• Durable Polycarbonate Construction: Manufactured from high-quality materials for enhanced safety and long-lasting mechanical durability.
• Simple Clip-In Installation: Designed to clip quickly and securely into any S-TEC Grid Plate (e.g., STI-1030, STI-1035), speeding up the installation process for electricians.
• Clean, Unmarked Lever: Features a simple, clean white switch lever without a luminous strip for a minimalist aesthetic.
• 2-Year Warranty: Backed by the S-TEC 2-year warranty, guaranteeing quality and reliable performance.

Benefits

• Enables Control from Unlimited Locations: The primary benefit of an intermediate switch. It allows you to add as many middle-of-circuit control points as you need, providing unparalleled convenience in large or complex spaces.
• Solves Complex Lighting Challenges: Provides the essential electrical mechanism for sophisticated lighting designs in open-plan homes, long corridors, and multi-story buildings.
• Enhanced Safety and Convenience: Eliminates the need to walk through dark spaces. You can turn on the lights upon entering a large room from any door and turn them off as you exit through another.
• Ultimate Installation Flexibility: As part of the modular system, it can be combined with other switch types on a single grid plate, perfectly tailoring the control solution to the room's specific needs.
• Handles Demanding Loads Safely: The 16 Amp rating provides a high safety margin for controlling multiple light fittings on a single, complex circuit.
• Professional and Efficient Installation: The secure clip-in mechanism simplifies the assembly of custom switch plates, saving time and labour on site.

In-Depth Technical Specifications

This section provides the detailed technical data for the S-TEC Module Intermediate Switch.

Ideal Use

The S-TEC Module Intermediate Switch is a specialized component used to add a third or subsequent switching position to a lighting circuit. It is always used in conjunction with two 2-way switches.

• Long Hallways and Corridors: Perfect for a hallway with doors at both ends and a door to a bedroom in the middle, allowing control from all three points.
• Multi-Level Staircases: Used for landings between floors, enabling control from the bottom, the landing, and the top of the stairs.
• Large, Open-Plan Rooms: Ideal for rooms with multiple entrances, such as an open-plan kitchen/dining/living area, where you want to control the main lights from any entry/exit point.
• Master Bedrooms: Allows for control of the main light from the doorway, as well as from switches on either side of the bed (requires one intermediate and two 2-way switches).

Tips

To ensure a safe and correct installation of your S-TEC Module Intermediate Switch, please consider the following critical expert recommendations.

• CRITICAL: MUST BE INSTALLED BY A QUALIFIED ELECTRICIAN: The wiring for an intermediate switching circuit is significantly more complex than standard 1-way or 2-way circuits. It MUST be carried out by a certified electrician to ensure safety, correct functionality, and compliance with all electrical regulations.
• CRITICAL: MUST BE USED WITH TWO 2-WAY SWITCHES: An intermediate switch CANNOT function on its own. It is designed to be installed on the "strapper" or "traveller" wires between two 2-way switches (like S-TEC module STI-1150M). A typical 3-point control circuit is wired as: [2-Way Switch] --- [Intermediate Switch] --- [2-Way Switch].
• Multiple Intermediate Switches: To create control from four, five, or more locations, you simply add more intermediate switches in the middle of the circuit. For example, 4-point control would be wired as: [2-Way] --- [Intermediate] --- [Intermediate] --- [2-Way].
• MODULE ONLY - GRID PLATE REQUIRED: This product is the switch mechanism module only. To complete the installation, you must purchase a compatible S-TEC Grid Plate separately (e.g., STI-1030 for a 1-lever plate).
• 4-Terminal Connection: Unlike 1-way (2 terminals) or 2-way (3 terminals) switches, an intermediate switch has four terminals. Your electrician will know how to correctly connect the two incoming and two outgoing traveller wires.
