Intermatic T104M Mechanical Timer Mechanism Only
Best for robust, legacy-style control in tough environments. This Intermatic mechanism is known for durability in industrial, commercial, and residential pools. It supports up to 40 A per pole, making it suitable for high-demand pool pumps. The 24-hour control with up to 12 ON/OFF operations per day allows precise scheduling, and the one-hour minimum ON/OFF times help avoid short cycling. Choose this for installations that require a proven mechanical timer with minimal electronics.
Who it’s for: homeowners with exposed equipment, pool service pros, and builders needing a rugged, low-maintenance timer. Limitation: this is a mechanism-only unit; a weatherproof box and wiring enclosure are required for outdoor use.
T104 Mechanical Timer Switch, 208–277 VAC 40 Amp
Best for DPST control of dual circuits in 240V systems. This timer provides a heavy-duty mechanical solution with a DPST configuration, suitable for running a pool pump and another device on separate legs. It handles up to 40 Amps and is ideal for high-demand fixtures like pool equipment, lights, or HVAC components. Selection is ideal when you need simultaneous dual-circuit control in a single unit. Caution: ensure enclosure is weather-rated if installed outdoors.
DEWENWILS Pool Pump Timer, Digital Timer Box
Best for flexible programming with multiple modes. This digital timer supports up to 20 ON/OFF schedules across 7-day repeat cycles or a single-day setting. It offers Always ON/OFF, AUTO ON/OFF, and DST modes, helpful for adjusting to daylight changes. It can manage up to two devices at once on 120–277 VAC and can withstand outdoor use with a weather-resistant shell. Caution: ensure the device matches your pool pump’s exact amperage and wiring requirements.
T104M Pool Timer Mechanism Only
Best for accurate, mechanical control in 240V systems. The T104M offers a 24-hour dial with 15-minute increments, four adjustable switches, and a dual-channel DPST arrangement. It supports up to 40A and is designed for heavy-duty pool pumps and HVAC loads. Best for installations where a dedicated mechanical timing mechanism is preferred, with a focus on reliability in variable temperatures. Limitation: requires wiring to a suitable enclosure and may need professional installation for outdoor use.
DEWENWILS Pool Pump Timer, Mechanical Box
Best for outdoor-ready, mechanical reliability. This DEWENWILS model provides 24-hour mechanical control with 4 adjustable switches and a rugged outdoor-rated enclosure.

Buying Guide
Key purchase considerations when choosing a 220V timer for a pool pump:
- Voltage and current: Ensure the timer supports 208–277 VAC and at least 40 A per circuit for most pool pumps.
- Mode and programming: Choose mechanical timers for simplicity and ruggedness, or digital timers for complex schedules and DST support.
- Enclosure: Outdoor installations require weatherproof or outdoor-rated enclosures to protect electronics.
- Single vs dual circuit: If you need to control two devices, pick a DPST or timer that supports multi-device operation.
- Backups and reliability: Some models include backup batteries to preserve settings during a power outage.
- Warranty and service: Consider warranty terms and available support when choosing a brand.
