Product information

Description

berker 138121 is a wall-mounted light switch designed for controlling lighting circuits in residential and commercial interiors. The unit features a black duroplast housing that provides mechanical strength and electrical insulation. Supplied as a pack of two, each switch measures 151 × 80 mm and is intended for flush installation in standard wall boxes or compatible mounting frames.

Advantages

The duroplast housing offers high resistance to impacts, scratches and ageing while remaining non-conductive and dimensionally stable. The compact 151 × 80 mm footprint fits many installation situations and the black finish provides a neutral, discreet appearance that integrates with varied interior styles. Pack of 2 delivery simplifies replacements or multi-point installations.

Suitable for

  • Switching indoor lighting circuits in homes and apartments
  • Use in offices, corridors and utility rooms
  • Replacement of existing switches with similar dimensions
  • Multi-point installations where two matching switches are required

Key specifications

  • Housing material: duroplast (thermoset plastic) for durability and electrical insulation
  • Colour: black finish for discreet integration
  • Overall dimensions: 151 × 80 mm (length × width)
  • Mounting: wall installation compatible with flush mounting and standard mounting frames
  • Package contents: two identical switches supplied together

How to use

Before installation, switch off the electrical supply at the distribution board and verify power is isolated. Remove the existing cover plate and disconnect wires, noting their positions. Secure the berker switch in the wall box or mounting frame using appropriate screws and attach wiring according to the room’s circuit layout, ensuring correct live and switched-live connections. Restore the cover plate and restore power to test proper switching operation. If unsure about wiring or local regulations, use a qualified electrician to install the product.

Usage recommendations

For long-term performance, avoid exposure to direct sunlight and severe mechanical stress. Clean the surface with a soft, dry or slightly damp cloth; avoid abrasive cleaners and solvents. Verify compatibility with existing frames and wall boxes before purchase to ensure a flush fit.
