Intermatic T105 – Frequently Asked Questions

1) Will the Intermatic T105 time switch work on a 120V circuit, and can it switch the load directly?
The T105 is built for 120 VAC, 60 Hz service, which is standard North American line voltage, and it switches most loads directly without a separate contactor. Both the clock motor and the contacts are on that same 120V supply, so it is not the right unit for a 208V or 240V panel feed.
2) What does SPDT mean on this Intermatic mechanical timer, and what can I wire to it?
SPDT here means one set of changeover contacts, 1 normally open and 1 normally closed. You can wire a load to the NO side so it energizes during the ON period, or to the NC side so it de-energizes during that period, or run two loads that alternate. That is what separates it from a plain single-pole ON/OFF timer.
3) Is the Intermatic T105 enclosure rated for outdoor or wet locations?
No. The T105 comes in a gray indoor metal enclosure only. Mount it in a mechanical room, electrical closet or other dry interior space. For an exterior wall, a parking lot pole or an irrigation pump, you need a weatherproof-enclosure version of the T100 series instead.
4) How many on/off cycles a day can the T105 24-hour timer be set for?
Up to 12 ON/OFF operations in a 24-hour cycle, with a 1-hour minimum between a trip ON and a trip OFF. That covers a typical retail or office lighting schedule, but if you need switching at 15 or 30 minute resolution, a 24-hour mechanical dial of this type is not the right choice.
5) Can I turn the lights on manually without disturbing the timer schedule?
Yes. The T105 has a manual override lever so maintenance staff can force the load on or off on demand, and the dial keeps running its programmed trips. Useful in schools, offices and retail where someone needs light outside the set hours.
6) How much wall space do I need to mount the Intermatic T105 timer?
Plan on a footprint of 7.875 in high by 5.125 in wide, with the enclosure projecting 3.625 in off the wall. Leave clearance in front of that depth so the cover can swing and you can reach the dial and trippers.
7) Should I use a mechanical time switch like the T105 or go with an electronic timer?
A 24-hour mechanical dial like the T105 makes sense when you want one repeating daily schedule, simple field setup by moving trippers, and no programming menus for the next tech who opens the box. Its limits are the 1-hour minimum interval, the same schedule every day (no separate weekend program), and the need for constant 120V power to keep the clock turning. If you need weekday/weekend differences or astronomic on/off, choose an electronic or 7-day control instead.
8) What is the correct part number to order for the Intermatic T105 and is it part of a larger series?
Order it as Intermatic T105. It sits in the T100 series of mechanical time switches, which is the family a spec or drawing usually calls out; the T105 is the 120V, SPDT, indoor metal enclosure member of that family. Country of origin is Mexico.
9) Is the T105 a good fit for scheduling lights across a portfolio of buildings?
It is aimed at indoor lighting control and general ON/OFF timing and scheduling, which is why it shows up in retail, office, school and healthcare common areas. Because every unit is the same 120V SPDT indoor metal-enclosure build, standardizing on it keeps one spare on the shelf and one set of instructions for every site.
