The switch assembly includes a shuttle formed of conductive material which is movable within a sleeve into and out of electrical contact with the retainer to illuminate and extinguish the bulb. The switch assembly also includes a rotor and a plunger movably disposed in the sleeve. The shuttle may be locked in electrical contact with the retainer by engaging teeth on the rotor with splines on the sleeve.
