All Clipsal electronic timers feature a remote connection facility which allows any number of remote push-button switches to be connected between this terminal and the neutral, to remotely trigger the timer. Timer switches are a convenient way of saving energy and money in areas where lights are usually needed for a limited or known time, such as pantries, stairways, bathrooms and storerooms.
The time can be set up to 254 minutes and comes in a range of colours.
