Sangamo Q563.3 4-Pin Time Switch - 3 On/Off Changeover Operations, 20A

The Sangamo Q563.3 is a 4-pin electromechanical time switch that controls up to three independent on/off changeover operations per 24-hour cycle, rated at 20A switching capacity. The unit runs on a quartz-driven 24-hour dial with manual pin placement to set switching times, and includes a 100-hour battery reserve to maintain programming through mains power interruptions.

Designed for DIN-rail mounting in distribution boards, the Q563.3 suits heating control, lighting schedules, pump timers and any application requiring daily repeating on/off cycles. The three changeover operations allow separate circuits to be switched at different times within the 24-hour period, so a single unit can manage morning heating, evening lighting and overnight circulation pump cycles without additional timers. The day omit dial allows individual days of the week to be excluded from the programme, useful for skipping weekends or public holidays.

The manual override button provides temporary control outside the programmed schedule without losing the pin positions, returning to automatic operation at the next programmed event. The 4-pin configuration uses mechanical pins inserted into the dial edge at the desired switching times, a format that remains visible and adjustable without requiring menu navigation or digital interface. The compact 104mm × 83mm × 134mm housing fits standard 35mm DIN rail and occupies four modular widths in a typical consumer unit.

Product Manual

What does the 100-hour battery reserve do?

The battery maintains the programmed schedule and current time during mains power interruptions of up to 100 hours, so the timer continues running correctly when power is restored without needing to be reset or reprogrammed.

How many on/off cycles can it control per day?

The Q563.3 supports three independent on/off changeover operations per 24-hour cycle. Each operation is set by placing a pin at the desired time on the dial edge, so the maximum is six pin positions (three on, three off) per day.

What is the day omit dial used for?

The day omit dial allows specific days of the week to be excluded from the programmed schedule, so the timer skips operation on selected days without removing the pin positions. This is useful for avoiding heating or lighting schedules on weekends or public holidays.

Can it be overridden manually?

Yes. The manual override button allows temporary control outside the programmed schedule. The timer returns to automatic operation at the next scheduled pin event, so the override does not erase the programme.
