Momentary Tactile Switch
The momentary SPST switch is the primary interface for the electronic flip-flop circuit. Over years of use, the internal dome contact inside this switch fatigues or accumulates carbon scoring, preventing the electrical pulse necessary to toggle the FETs between bypass and effect modes.

1/4" Mono Input Jack
Boss pedals utilize a switching input jack that connects the battery's negative terminal to the circuit ground only when a 1/4 inch cable is inserted. Physical deformation of the internal shunt or oxidation on the sleeve contact prevents the device from powering on, which manifests as the pedal failing to engage.

9V Battery Clip
Because the DS-1 is frequently used with 9V batteries, the lead wires at the snap connector are subject to significant mechanical stress and chemical corrosion. A fractured wire or high-resistance connection at the snap prevents the switching logic from receiving stable current, rendering the footswitch unresponsive.
