You pull the cord, and instead of a satisfying click, it sticks, judders, or doesn't switch at all. It's annoying - and it can be dangerous. Shower pull-cords take a lot of abuse, and they're not meant to last forever. Here's what's going on.
The Why: What's Actually Going On
Electric showers draw a lot of current (often 8.5-10.5 kW). The pull-cord switch is a high-amperage isolator (typically 45A or 50A) that has to break that load every time you switch off. Arcing and heat cause the contacts to wear and can leave carbon build-up. Over time, the mechanism becomes stiff or sticks. Older switches may also have worn springs or damaged cords. Using the pull-cord as the everyday on/off (instead of the shower's own controls) accelerates wear. They're designed as isolators for maintenance, not daily switching.
Roy's Pro Tip
Use the shower's built-in controls to turn it on and off. Reserve the pull-cord for isolation (e.g. when cleaning or during work). This can significantly extend its life.
Safety Warning
If the switch feels hot, sparks, or smells of burning, isolate the circuit at the consumer unit and call an electrician immediately. Never force a stuck pull-cord - you risk electric shock.
