Magnetic Autofill Relay Microswitch
This microswitch senses the boiler float's magnet through the boiler wall and turns on as the water level drops, activating the fill solenoid. Rated 0.4A at 250V with a normally-open contact.
SPECIFICATIONS
- Rating: 0.4A, 250V, normally open (NO) contact
- Switch head: 65 x 20 x 9mm
- Wire lead length: 500mm
COMPATIBILITY
- Fits: Boiler autofill systems using a magnetic float and reed-style microswitch
INSTALLATION
Straightforward DIY swap for anyone comfortable with basic low-voltage electrical connections. See the manufacturer's spec sheet for reference.
PRO TIPS
- If the boiler won't autofill (or overfills) but the float itself moves freely, this reed microswitch, not the float, is the more likely failure point, since it's a purely magnetic, contactless sensor that degrades over time.
