Anderson Timer

Post by Dennis_Brown » Mon Jun 01, 2020 4:08 pm

Looking thru some old timers I noticed the Anderson Timer has a smaller diameter circle for the contacts. What does the roller assembly look like that attached to the cam compared to other roller assemblies?

Anderson timers use a 'flapper' rather than a roller. The flapper swipes across the contact spot in the timer instead of 'rolling' or 'rubbing' around the edge as regular timers with rollers or brushes do.
It seems you either like them or you don't. I like them and have had good running experience (i.e. no problems, always work, last a long time).

I have an original Anderson timer with all the company patient data embossed that Frank Fenton rebuilt for me like 15 years ago, and it works like a champ. Frank was reproducing the Anderson Timer back when he and I were on the MTFCI board of directors.

Dennis, a more recent approach is a Vane actuator used by the I-Timer. Rather than a roller, flapper or brush; the 4 magnets tell the Timer which coil to activate and the windows cut in the outer diameter tell the timer when to activate the coil without any physical contact so its maintenance free and never wears out. A single sensor is used to detect window openings so the Vane actuator is immune to timing cover misalignment about the CAM (concentricity) to minimize coil to coil timing variations.
