24hr Interval Timer

The AB54 series of timers are basic interval timers requiring the interval to be reset manually at the beginning of each cycle. The timer features an external friction which provides low setting-torque and enables the setting to be changed during the cycle without damage. The load switch is an isolated single pole, double throw on the standard unit, however, the AB54 is available with a double pole, double throw on special order. Standard shaft rotation is clockwise when timing. Timing can also be started by rotating the shaft in either direction. Knobs and dials are available as separate items.
