On Trigger is a Czech Republic-based manufacturer of electronic drum triggers, founded in 2014 by a drummer searching for a more reliable way to reinforce live bass drum sound. Rather than relying on triggers attached to a vibrating drumhead, the company developed a sensor system that mounts to the underside of a kick pedal's baseplate, capturing the strike at the source. Development began in 2013, with a public demonstration in 2014 used to establish prior art in lieu of a patent.

The core lineup centers on the On Trigger Gen.3, a universal kick pedal trigger compatible with any pedal that has a fixed baseplate, attached via integrated adhesive strips and offering adjustable sensor pressure. The brand also makes a Snare/Tom trigger and sells replacement sensors as spares. Models are offered with either an XLR (M) output or a 6.3mm mono jack, and the triggers are designed to feed standard drum modules with dynamic velocity sensing, set up similarly to electronic drum pads.

Products are designed and built in-house in the Czech Republic, and the company is now on its third generation of the kick trigger design. The founder has stated a deliberate preference for avoiding endorsement deals in favor of word-of-mouth promotion, with pricing aimed at being accessible to both working professionals and developing drummers.

On Trigger has 2 products cataloged on Equipboard, including Electronic Drum Hardware and Triggers. Their gear is featured by 1 artist, with the strongest followings in Rock and Metal. Notable users include Alex Rüdinger.
