Intermatic 156T1948A Trippers

The Intermatic 156T1948A Trippers are essential mechanical components designed for precise time switch programming within professional HVACR and aquatic control systems. This replacement tripper kit is engineered for high-cycle reliability, providing the physical interface necessary to trigger the internal cam of Intermatic T100, T170, T1400, and T1800 Series mechanical timers. Each set includes one ON tripper and one OFF tripper, allowing contractors to establish automated scheduling for heavy-duty loads such as pool pumps, industrial lighting, and machinery. These metal timer pins feature a robust screw-on mounting design that prevents slipping or timing drifts, ensuring the mechanical clock dial maintains accurate operational cycles. When secondary cycling is required or original pins are lost, these 1on/1off trippers provide a direct OEM-spec solution for 24-hour time switches and skipper wheel configurations.

Key Benefits:

• Universal Series Compatibility: Fits Intermatic T100, T170, T1400, and T1800 series dials for versatile field application.
• Secure Screw-On Installation: Features a built-in set screw to lock the timer tripper firmly against the clock dial.
• Durable Metal Construction: Manufactured from high-grade metal to withstand repetitive mechanical movement and environmental stress.
• Precise Load Control: Enables the expansion of ON/OFF cycles on compatible 24-hour mechanical time switches.

Common Questions:

How many trippers can be installed on a single T170 series dial?
Most models support up to 12 pairs of trippers, provided there is a minimum one-hour interval between the ON and OFF operations for proper mechanical clearance.

Will these trippers work with the green or brass skipper wheels?
Yes, the 156T1948A includes the necessary skipper extension functionality to interact with the day-skipping mechanisms found in the T170 and T1400 series.

Do I need specialized tools for installation?
A standard small flat-head or Phillips screwdriver is required to tighten the tripper's set screw onto the edge of the clock dial. Ensure the screw is firm, but do not overtighten to avoid damaging the dial edge.
