The K&S Momentary Switch is a universal starter or kill switch designed for use on 7‑inch and 8‑inch handlebars. It operates in a momentary fashion, engaging only while the button is depressed. In its normal (non‑pressed) state the switch leaves the circuit open, ensuring that power is disconnected until the switch is actively engaged.
Installation requires mounting the switch on a compatible 7‑inch or 8‑inch handlebar. Connect the switch terminals to the motorcycle’s ignition or starter circuit, observing correct polarity. When the switch is pressed, the circuit closes, allowing power to flow; releasing the switch returns the circuit to the open state, cutting power. This configuration provides a reliable, single‑handed method to start or kill the engine.
