Impulse Relay FF BIS-402 230V 16A for Flush Mounting in Junction Box

Impulse relay FF BIS-402 230V 16A for flush mounting in junction box is a single-channel, 230 V switching device engineered for concealed installation. The module provides momentary (impulse) switching of lighting or low-voltage circuits from one or multiple push-button inputs, enabling centralized control without visible wall-mounted relays. Its compact format fits standard junction boxes and is intended for both residential and commercial electrical installations where space-saving and hidden control are required.

Advantages

The impulse relay offers reliable single-pole switching with a nominal current rating of 16 A at 230 V, suitable for most lighting loads and small actuators. Designed for flush mounting, it minimizes visible hardware in interiors and supports multiple push-button inputs for flexible control points. The device reduces wiring complexity by converting momentary button signals into maintained switching states, and its compact housing simplifies installation inside standard junction boxes.

Suitable for

• Centralized on/off control of domestic and commercial lighting circuits
• Staircase or corridor lighting with multiple push-button stations
• Integration with low-voltage control circuits for blinds or small motors (within current rating)
• Concealed installations where wall space is limited or aesthetics require hidden devices

Key specifications

• Supply voltage: 230 V AC
• Nominal switching current: 16 A
• Single-channel impulse (momentary) switching operation
• Designed for flush mounting inside a junction box
• Compatible with one or multiple momentary push-button inputs

How to use

Install the impulse relay inside a standard junction box according to local electrical regulations and wiring practices. Connect the 230 V supply and the load to the relay terminals, and wire one or more momentary push-button switches to the control input. After powering the device, each brief press of a connected push-button will toggle the output state, switching the connected lighting or controlled circuit on or off. Ensure the connected load does not exceed the relay's 16 A rating and observe correct polarity and grounding where applicable.

Usage recommendations

Use the relay with loads within its rated current and ensure secure terminal connections. For circuits with inductive loads or motors, verify suitability and consider adding appropriate protection or suppression components. Follow national wiring codes and, if unsure, consult a qualified electrician for installation and testing.
