Onesto Bell Press Module

• A high-quality momentary switch mechanism designed to integrate doorbell, gate, or other momentary controls seamlessly into the Onesto Oracle modular system.
• This is a module only; it is the functional internal push-button and not a complete, standalone switch.
• Engineered to provide a momentary action, meaning it completes an electrical circuit only for as long as the button is physically pressed.
• Allows electricians and designers to create custom control panels with a consistent, high-end aesthetic that matches the entire Oracle range.
• Features a robust 16A-rated mechanism, ensuring reliable performance for a wide range of signalling applications.
• Requires a compatible Onesto Oracle Grid Plate for housing and an Onesto Oracle Surround for a finished appearance (both sold separately).
• Available in both White and Black Graphite to perfectly match the corresponding Oracle grid plates and accessories.

Features

• Switch Functionality: Provides a momentary (non-latching) push-button action, ideal for signalling applications.
• Modular Design: A core "S-size" component of the Oracle system, designed to clip securely into any compatible Oracle grid plate.
• Robust Rating: Features a durable 16A, 250V AC mechanism, ensuring longevity and reliable contact-making.
• Premium Construction: Built with a high-quality, self-extinguishing polycarbonate body for safety and a long mechanical life.
• Core Colour Options: Available in White or Black Graphite to maintain colour consistency with the chosen grid plate.
• Standardized Form Factor: Designed as a standard "S-size" module for a perfect, secure fit within all compatible Oracle yokes.
• Certified and Compliant: Manufactured to meet the stringent safety and performance requirements of SANS 60669-1.
• Assured Reliability: Backed by a comprehensive 5-year manufacturer warranty.

Benefits

• Flawless Design Cohesion: The primary benefit is the ability to have your doorbell or gate control button perfectly match the sophisticated design of your light switches and sockets.
• Eliminates Unsightly Buttons: Replaces generic, mismatched plastic bell press buttons with a premium, integrated solution.
• Ultimate Customisation: Allows for the creation of unique control plates, such as combining a bell press with a light switch in a single 4x2 grid for a front door entrance.
• Professional Performance: Engineered for reliability, the module delivers a crisp, tactile, and dependable momentary action every time.
• Cost-Effective Maintenance: In the unlikely event of a mechanical failure, only this inexpensive module needs to be replaced, not the entire switch plate and surround.
• Simplified Inventory for Electricians: Contractors can stock this single module to service or create any bell press configuration within the Oracle range.

In-Depth Technical Specifications

The Onesto Bell Press Module is the functional component for momentary switching in the Oracle system. The following table details its complete technical specifications.

Ideal Use

This module is exclusively intended for professionals creating custom switch assemblies for momentary applications.

• Doorbell / Chime Systems: The most common application, used as the main push-button at an entrance to activate a doorbell.
• Gate and Garage Door Motors: Ideal for wiring an indoor, wall-mounted "open/close" button for motorised gates and garage doors.
• Access Control Systems: Frequently used as a "request-to-exit" (REX) button on the secure side of a door controlled by an electronic lock.
• Industrial Control Panels: Can be used for low-voltage control circuits requiring a "jog" or "inch" function for machinery.

Tips

To ensure correct purchasing and safe installation, it is critical to understand the specific function of this module.

• CRITICAL - THIS IS NOT A LIGHT SWITCH: This is a momentary switch. It only stays ON while you are pressing it. If you use this for a light, the light will turn off the moment you take your finger off the button. For standard lighting, you need a latching switch module (ONM001 or ONM002).
• CRITICAL - COMPONENT PART ONLY: You are purchasing only the internal push-button mechanism. To create a complete, functional unit, you MUST also purchase an Onesto Oracle Grid Plate and an Onesto Oracle Surround separately.
• Example Assembly (To build one complete bell press): You will need three separate items:
  1. This Module (ONMBEL or ONMBELBK)
  2. An Onesto 1 Lever Grid Plate (ON2011Y or ON2011YBK)
  3. An Onesto 4x2 Decorative Surround (e.g., ON2000S-P)
• Professional Installation is Mandatory: Wiring this module to a transformer, chime, or motor control board must be performed by a qualified electrician to ensure safety and prevent damage to the connected equipment.
• Exclusive Compatibility: This module is designed to fit ONLY in Onesto Oracle grid plates. It is not compatible with other Onesto ranges or any other brand.
