Reliable pool and commercial equipment scheduling depends on durable mechanical timers that can handle higher voltages and heavy electrical loads. The Intermatic T104M 24-Hour Mechanical Time Switch Mechanism is designed to provide dependable on/off control for pool pumps, lighting, heaters, and other electrical equipment operating on 208–277 volts.

This mechanism-only replacement is commonly used when the existing timer enclosure and wiring remain in good condition, but the internal clock mechanism has failed or become unreliable. By replacing just the mechanism, system functionality can be restored without the need to rewire or replace the entire timer box.

Built for continuous duty and proven in commercial and residential pool applications, the T104M is a trusted solution for time-based equipment control.

Heavy-Duty Timing Control for High-Voltage Applications

The T104M is engineered for higher-voltage electrical systems often found in commercial pools, apartment complexes, and larger residential installations. Its 40-amp switching capacity allows it to control high-load equipment reliably over repeated daily cycles.

The 24-hour dial provides straightforward scheduling, allowing users to set precise on and off times to manage circulation, lighting, or auxiliary equipment efficiently.

Mechanism-Only Replacement for Existing Enclosures

This product includes the mechanism only, making it ideal for servicing existing Intermatic timer enclosures. When the enclosure, wiring, and conduit are still in good shape, replacing just the mechanism is a cost-effective repair option.

The T104M drops into compatible Intermatic enclosures, restoring accurate timing control without disturbing existing electrical connections.

Built for Long-Term, Continuous Operation

Mechanical timers are often exposed to heat, vibration, and constant use. The Intermatic T104M is built with durable internal components designed for long service life under demanding conditions.

Its proven mechanical design continues to make it a preferred choice for pool professionals who prioritize reliability over complex electronic controls.

Why Mechanical Time Switches Still Matter

Mechanical timers remain a dependable choice for many pool systems.

Using a mechanical time switch helps:

• Maintain predictable daily equipment schedules

• Handle high electrical loads reliably

• Reduce unnecessary equipment runtime

• Support energy-efficient pool operation

Simplicity and durability make mechanical timers a long-standing industry standard.
