Brand: Intermatic · SKU: 107SB189 · UPC: 078275100374 · Category: Controls & timers · Type: Parts & Accessories
The Intermatic 107SB189 is a red tripper marked ON, used with 24-hour mechanical time switches. Trippers like this one are the small clips mounted on the timer's rotating dial that engage the switch mechanism at a set time of day, and the red color identifies this piece as the ON tripper as opposed to its OFF counterpart. This part is listed as compatible with the SB Series, HB112C, HB113C, and HB114C indoor units, the AL300RTW, AL600TW, AL900TW, and AL60TW models, and the ML Series transformer timers. An electrician or technician replaces a tripper of this type when the original has broken off or been lost, restoring the timer's ability to switch a circuit on at the intended time. Because it is a small mechanical wear part rather than an electrical component, this tripper is typically sold in support of ongoing maintenance on existing Intermatic timer installations.
Red identifies it as the ON tripper for the timer.
SB Series, HB112C, HB113C, HB114C (indoor), AL300RTW, AL600TW, AL900TW, AL60TW, and ML Series transformer timers.
