A novel construction for a multifunctional rotary switching device is provided. The body of the switch includes a radial array of switching contact arms, each arm being connected at one end to a central hub. The switch is preferably stamped from a thin sheet of flexible metallic material having magnetic characteristics. The switch is then installed onto a printed circuit board switching substrate with the central hub of the switch being rigidly connected to the switching substrate with the contact arms in a normally closed state. A magnet is installed into a rotatable actuator in close proximity to the surface of the switch whereby the magnetic force of the lifts the contact arm of the switch over which the magnet is aligned. In this position, the magnet opens the corresponding contact arm of the switch.
