ELKO EP MSB3 Series Metal Switch Buttons
Product Overview
The MSB3 series metal switch buttons from ELKO EP are advanced control units designed for modern smart home and building automation projects. These buttons feature premium metal plates available in antique copper, satin brass, brushed silver, and graphite black finishes, offering a sophisticated aesthetic.
The series includes three models: MSB3-40 with four touch buttons, MSB3-60 with six touch buttons, and MSB3-90 with nine touch buttons. All buttons can be easily configured via software to control various functions or macros, allowing for versatile operation, such as controlling multiple appliances simultaneously with a single button press.
Each metal switch button is equipped with an integrated temperature sensor for ambient temperature monitoring. Additionally, they feature an analog-to-digital input (AIN/DIN) that supports connecting potential-free contacts or external temperature sensors (like TC/TZ, suitable for floor temperature measurement).
Key advantages over conventional switches include space-saving design, the ability to signal the status of system outputs, integrated temperature measurement capabilities, and the flexibility to connect external buttons or detectors. Individual buttons can be illuminated in white for visual feedback.
The MSB3 series buttons are designed for mounting into standard installation boxes, with all versions fitting the standard module size of 94x94 mm.
Model Variations and Finishes
The MSB3 series offers a range of finishes for both the decorative plate and the control buttons, allowing for customization to match interior design.
Available Finishes:
- G: Satin Brass
- B: Graphite Black
- S: Brushed Silver
- C: Antique Copper
The model naming convention indicates the finish combination, for example:
- MSB3-XX/BB = Graphite black plate + Graphite black button
- MSB3-XX/GG = Satin brass plate + Satin Brass button
- MSB3-XX/SS = Brushed silver plate + Brushed silver button
- MSB3-XX/CC = Antique copper plate + Antique copper button

Connection Diagrams
The MSB3 series supports various connection configurations for smart home integration.
Connection Diagram 1: Single Input
This diagram illustrates the connection of a single input for free potential contacts, such as a standard button or a motion sensor, to the iNELS BUS system. It shows the necessary terminals for power (+BUS, -BUS) and the input connection for the button or sensor.
Connection Diagram 2: External Temperature Sensor
This diagram details the connection of an external temperature sensor (TC/TZ type) to the iNELS BUS system. It shows the power terminals (+BUS, -BUS) and the input terminals (AIN1/DIN1 and AIN2/DIN2) where the external sensor is connected for temperature measurement.
