Valokytkin Berker 503404, yksinapainen 10 A 250 V, metalliviimeistely

berker 503404 is a single-pole light switch with a metallic finish, designed for wall-mounted electrical installations in homes and commercial spaces. Rated for 250 V and 10 A, the switch controls a single circuit and is suitable for standard lighting loads and basic electrical devices. The compact form factor and durable materials make it appropriate for replacing or installing as a primary on/off control where a conventional inline switch is needed.

Advantages

The metallic finish provides a uniform, neutral appearance that integrates with modern and classic interiors while offering surface resistance to everyday wear. As a single-pole device rated for 10 A at 250 V, it supports typical lighting circuits and simple inductive or resistive loads within that rating. Its compact design simplifies installation in standard wall boxes and reduces protrusion from the mounting surface.

How to use

Disconnect power at the distribution board before installing or servicing the switch. Mount the switch into a compatible flush-mounted back box and connect the line and switched line conductors to the designated terminals according to local wiring standards. Ensure secure terminal connections and proper insulation, then restore power and test the switch operation by toggling it on and off to verify control of the intended lighting circuit.

Recommendations

Use the switch only within its rated voltage and current limits (250 V, 10 A). For loads approaching the rated current or for inductive loads, verify compatibility with the connected equipment and consult an electrician if in doubt. For safe and reliable operation, install the device in dry, indoor environments and avoid exposure to direct moisture or corrosive conditions.
