NSi Industries On/Off Tripper Pair for 24-Hour Dial Timers

The NSi Industries On/Off Tripper Pair for 24-Hour Dial Timers is a purpose-built replacement component designed to restore accurate switching action on 24-hour dial time switches. This matched on/off tripper set mounts directly onto the dial mechanism, allowing electricians and maintenance technicians to re-establish precise programmed on and off events without replacing the entire time switch. Engineered as a direct-fit accessory for 24-hour dial timers, this pair is a practical, cost-effective solution for keeping existing mechanical time controls in reliable service across commercial and industrial facilities. Instead of swapping out an entire time-switch mechanism when a tripper wears out or is lost, facility electricians can install this matched on/off pair and return the dial timer to accurate, repeatable operation quickly and affordably.

Key Features

  • On/Off Pair Configuration: Matched tripper set engineered specifically for 24-hour dial time switches, sold as a coordinated on/off pair.
  • Direct-Fit Compatibility: Designed to install onto the 24-hour dial mechanism for accurate program timing without modification.
  • Simple Drop-In Replacement: Allows quick restoration of on/off switching function without replacing the full time switch assembly.
  • Dependable Mechanical Actuation: Supports consistent, repeatable on and off tripping for scheduled load control applications.
  • Maintenance-Friendly Design: Lets technicians service and extend the working life of existing 24-hour dial timer installations.
  • Cost-Effective Repair Part: Provides a lower-cost alternative to replacing an entire dial time switch when only the trippers need renewal.

Technical Specifications

NSi P47 – Frequently Asked Questions

1) What exactly comes in the NSi P47 tripper pair?
The NSi P47 is a matched set of two trippers for a 24-hour dial time switch: one on tripper and one off tripper, sold together as a coordinated pair. That gives you one complete on/off event. If you schedule more than one on/off cycle per day on the same dial, you need additional pairs.
2) Do I have to replace the whole time clock if a tripper is broken or missing?
No. The P47 pair mounts onto the existing 24-hour dial mechanism, so a worn or lost tripper is a parts repair, not a unit swap. Maintenance techs can reset the on and off events and return the clock to accurate scheduling without pulling the time switch out of the panel.
3) Will these trippers work on a 7-day or astronomic time switch?
These are specified for 24-hour dial time switches only. A 7-day dial or a skipper-wheel clock uses different tripper geometry, so a 24-hour pair is the wrong part for those mechanisms. Match the tripper to the dial type on the clock in front of you.
4) Is a tripper pair a mechanical part or does it carry current?
It is purely mechanical. The trippers ride on the dial and physically actuate the switch mechanism at the programmed times, so there is no wiring, no voltage rating to match, and no load rating involved. The switch contacts inside the clock still handle the load; the trippers only tell them when to change state.
5) What kinds of loads do dial timers with these trippers usually control?
Typical uses are commercial lighting control, exterior and signage lighting, HVAC and mechanical equipment scheduling, and irrigation or pump timing. Any of those running off a 24-hour mechanical dial clock is a candidate when the trippers wear out.
6) Should a facility keep spare trippers on the shelf?
If you maintain a fleet of mechanical dial time switches, yes. Trippers are the part that gets lost during reprogramming or wears from years of cycling, and a missing one takes a lighting or HVAC schedule out of service. Stocking matched P47 pairs means the repair is same-visit instead of a return trip.
7) Where do I find the full manufacturer specs for the NSi P47?
NSi publishes a spec sheet for the P47 tripper pair at https://media.distributordatasolutions.com/nsi/2020q1/7cb93d65abd25cdbf8932eb6cdb11c94c3586833.pdf. Use it to confirm the tripper fits the specific dial timer model you are servicing before you order.
