Push Button 20 mm Black SPST

Momentary push button switch with 20mm mounting hole diameter and black cap. This SPST (single pole, single throw) switch provides momentary contact when pressed, returning to open position when released. The larger 20mm size provides easier actuation compared to smaller 4mm buttons.

Commonly used on racing dashboards for functions like DRS (drag reduction system), pit limiter, ignition kill, or other temporary activations. The black color matches most dashboard finishes. Rated for 12V DC automotive/racing electrical systems.

This is an OEM replacement part used in various Rush SR dashboard installations.
