Round Pattern (RPTS) Standard time switches are robust, 20amp switches that are ideal for the switching of heating and lighting applications- up to three times a day. The S255 has a 4-pin base which means it has independent motor connections which enable a different switching circuit voltage from the voltage powering the time switch. The day omit feature means you can skip any day of the week if necessary. There is also a manual override button for your convenience. The S255 is a fit-and-forget time clock.

You can also isolate the switching circuit independent of the supply to the clock. DOWNLOADS S255 Datasheet [PDF] RPTS Standard Instructions [PDF]
