I would have expected the switch to come with screws or bolts to fix it to the boat. It didn't even have the type or size of fixing screw/bolt to buy. The switch itself was good though.

Simple and sturdy

A nice simple and sturdy switch, ideal for isolating the battery on our RIB and with the fixed knob it does away with the problem of losing a removable knob/key. Good service and delivery.

Perfect solution

Used as isolator for van leisure battery supply and fitted behind passenger seat. Neat smart and solid feel with visible indicator. Better than the 'key' style ones.

Just the Job

After repeated flat batteries on my campervan I can now isolate and forget it over the winter. Hurrah!

I needed a switch to isolate my stern thruster and most of the options, were very expensive in comparison. This is a nice solution with a meaty twist action, that feels good and is a neat self-contained solution.
