SHOWER SWITCH

Technical Specifications • Current Rating: o 45A (Standard): The most common rating for modern instant showers (up to 9.5kW–10.5kW). o 20A: Typically used for smaller storage water heaters or low-power (3kW–4.5kW) systems. • Voltage: Rated for 220V – 250V AC (50/60Hz). • Switch Type: Double Pole (DP). This is a critical safety feature that disconnects both the Live and Neutral wires simultaneously to ensure the appliance is completely isolated from the power supply. • Plate Dimensions: Standard square plate is 86mm x 86mm. • Back Box Depth: Requires a deeper back box, typically 35mm to 47mm, to accommodate the thicker heavy-duty cables (e.g., 4mm² or 6mm²). • Materials: Constructed from fire-retardant Polycarbonate, Bakelite, or Urea Formaldehyde to withstand high temperatures without melting. Key Features • Neon Indicator Light: A red light that clearly indicates whether the switch is currently "ON". • Mechanical Indicator: High-quality models often include a physical "ON/OFF" label on the rocker itself as a backup to the neon light. • Heavy-Duty Terminals: Features high-conductivity brass terminals designed to securely grip thick cables and prevent loose connections that cause overheating. • Pull-Cord Variant: In some installations, a ceiling-mounted pull-cord switch (rated 45A or 50A) is used to allow safe operation from within a damp bathroom environment. • Compliance: Should meet BS 3676 or BS EN 60669-1 standards.
