Intermatic makes time controls, photocontrols and surge protective devices, and this page leans heavily on timers. Choose by how the load needs to be scheduled. Electromechanical 24 hour time switches repeat the same on and off every day using trippers set on a dial. Spring wound countdown timers run a set interval and then shut off, and are ordered by maximum time, switch configuration such as SPST, SPDT or DPST, and whether a hold position is included. Astronomic timers track sunrise and sunset rather than fixed clock times.
Common questions
What does the hold option on a spring wound timer do?
A timer with hold has a position past the maximum setting that keeps the load energised until somebody turns it back. Without hold, the load always drops out when the spring winds down. Bathroom fans and heat lamps are commonly specified without hold precisely so they cannot be left running unattended.
SPST, SPDT or DPST, which switch configuration do I order?
SPST breaks one ungrounded conductor. DPST breaks two, which is what a 240 volt load or a switched neutral arrangement needs. SPDT gives a common with normally open and normally closed contacts, so it can transfer between two circuits. Match the configuration to the load voltage and to how many conductors have to open.
Will a water heater time switch handle my tank?
Water heater time switches are rated for the voltage and resistive load of a tank element, commonly 240 volt in a NEMA 1 enclosure meant for indoor mounting. Compare the element wattage against the switch rating, and confirm the enclosure type suits the location. Damp or outdoor mounting calls for an enclosure rated for that environment.
Should I order the mechanism only or a complete timer?
Mechanism-only listings, such as the 24 hour defrost timer mechanism, are replacement internals for an existing enclosure and arrive without a case or cover. New installations need the complete unit. If you are servicing a working setup where only the clock motor or contacts gave out, the mechanism is the cheaper repair.
Can an Intermatic timer ship to a site outside the GTA?
Yes. Orders go Canada-wide and typically arrive in 3 to 7 business days. Ontario and Quebec orders over $150 ship free, and the rest of Canada takes 10 percent off at checkout. If you are holding a better written price from another Canadian supplier, the price match guarantee applies to this page too.
