Emnrod T104M Mechanical Time Switch DPST, 208-277V, 40A | 24-Hour Dial with 4 Trippers

Reliable high-load timing for pools, lighting, and HVAC

The Emnrod T104M is built for demanding environments, delivering dependable mechanical control for equipment that runs at full power. Crafted with industrial-grade materials and copper windings, this timer supports up to 40A on 208–277V, and its double-pole, single-throw (DPST) configuration enables dual-circuit management from a single device. Whether you’re coordinating a pool pump and filtration, outdoor lighting, or HVAC accessories, the T104M provides a sturdy, single-point timer solution designed to endure.

Key design elements matter in real-world use: a compact footprint that fits most waterproof boxes, carefully labeled wiring diagrams to simplify setup, and a purely mechanical mechanism that minimizes electronic failure risks in damp or dusty environments. The timer also ships with four ON/OFF trippers, offering flexible scheduling and reducing the need for frequent adjustments in changing conditions.

• industrial-grade construction and copper windings for lasting performance.
• supports 208–277V and resistive loads up to 40A.
• DPST design for coordinating two circuits from one device.
• 4 trippers and a 24-hour dial enabling up to 12 daily on/off cycles.
• 15-minute interval markings for accurate scheduling.
• Manual bypass: instant device control without altering preset programs.

In practice, the T104M shines in settings like outdoor pools, signaled outdoor lighting, irrigation systems, fans, and other high-power equipment across homes, commercial spaces, and light industrial environments. Its robust design helps keep routine automation predictable, even as conditions change.

• Ideal applications: pool pumps, pool heaters and filters, outdoor lighting, irrigation controllers, fans, and indoor/outdoor signage.
• Environment compatibility: suitable for residential, commercial, and some industrial installations requiring reliable, high-capacity control.

Easy installation is part of the package: clearly labeled wiring diagrams, a compact form factor, and a note to push the dial into the gear mechanism to ensure proper operation. Regular maintenance of bearings and gears helps keep the mechanism smooth and extend service life.
