27.26.8.230.4000 Finder Step relay Clamp terminal

Why Choose the Finder 27.26.8.230.4000 Step Relay?

The Finder 27.26.8.230.4000 is an electromechanical step relay (impulse relay) from the Finder Series 27, designed for controlling lighting and other suitable electrical circuits using momentary push-button commands. Its impulse-operated switching mechanism makes it particularly useful for installations where the same lighting circuit needs to be controlled from several locations.

Unlike conventional contactors that require a continuously energised coil to maintain their switching position, the Finder Series 27 step relay uses a mechanically maintained switching mechanism. Each control impulse advances the relay's contact position, allowing the load to remain switched without continuous coil energisation.

The 27.26.8.230.4000 is designed for a 230 V AC control supply and provides a practical solution for lighting control in residential, commercial and building services installations. Its electromechanical design supports convenient switching through compatible momentary push-buttons.

Key Advantages

• Electromechanical step relay designed for impulse-operated electrical switching.
• 230 V AC control coil for compatible mains-voltage control circuits.
• Mechanically maintained contact positions eliminate the need for continuous coil energisation.
• Enables lighting control from multiple push-button locations.
• Suitable for residential and commercial electrical installations.
• Simple integration with momentary push-button switching circuits.
• Finder Series 27 construction for dependable lighting control applications.

Key Features

• Finder Series 27 electromechanical step relay.
• Impulse-operated switching mechanism.
• 230 V AC nominal coil voltage.
• Mechanically maintained switching positions.
• Momentary electrical pulse operation.
• Suitable for multi-point lighting control.
• No continuous coil supply required to maintain the selected switching state.
• Designed for integration into compatible building electrical installations.

Reliable Impulse Switching for Lighting Systems

Step relays such as the Finder 27.26.8.230.4000 allow a connected electrical load to be controlled using short electrical impulses rather than a continuously applied control signal. The relay's mechanical switching mechanism maintains the selected contact position between impulses, helping reduce continuous control-circuit power consumption.

This method is particularly useful in stairways, corridors and buildings with multiple switching points. Several momentary push-buttons can be connected into a suitable control arrangement, allowing users to operate the same lighting circuit from different locations without complex conventional multi-way switching arrangements.

Typical Applications

• Residential lighting control circuits.
• Stairway and corridor lighting installations.
• Multi-point push-button lighting control.
• Commercial building lighting systems.
• Building refurbishment and electrical installation projects.
• Impulse-operated electrical switching circuits.
• Building services and lighting automation installations.
