Isolator Switch | Onesto Trinity Range

The Onesto Trinity Isolator Switch is a double-pole or triple-pole switch used to isolate higher-current circuits and equipment, such as pumps, geysers, motors and other fixed appliances, where a standard 20A switch is not rated for the load.

It is a simple, budget-friendly choice for domestic and light commercial isolation switching.
