This is a top quality and very versatile 230V switch which can be used for remotely operating power tools such as routers or circular saws when mounted in tables. Just mount this switch onto the table, plug your router or saw into the 13A socket, switch your machine on and then plug the NVR switch into a convenient power outlet socket (1.5m cable included) - now you can control the router or saw via the NVR switch. You may need to devise a way of holding the machine switch in the 'on' position with a cable tie or something similar. Many other switching tasks such as remotely controlling an extractor fan or ventilator can be done with this unit. Modification to the mounting bracket maybe required. N.B. maximum power tool capacity: 2,000W, maximum induction motor size: 1.1kW.
