Yes, in the past I've seen kit that has a push-pull mechanical Bowden-cable type arrangement between a front-panel on/off control and the actual switch/power-supply (this was in telco gear, where you really didn't want to extend the rather thick 48VDC-at-tens-of-amps supply-cables from the rear of the case to a front-panel switch).

Though they got the ergonomics wrong and had 'knob-pushed-in' as off, so you had to be very careful not to nudge the knob while adjusting any other controls.
