Abstract
An ignition switch has contact plates held in a socket plate and with trip cams on the circumference of the socket plate. A switching wheel carries a plurality of contact springs, which abut on one side against a central contact and have contact arms switchable by means of the trip cams with respect to the contact plates. The contact springs also cooperate with a starter repetition lock. The central contact is in the form of a spherical shell segment and each contact spring has a spherical shell segment pressed with a prestressing force onto the spherical shell segment.
Claims16
In an ignition switch having a socket plate provided with a generally circular array of contacts and a central contact, and a switching wheel rotatable in a forward direction about an axis coincident with the axis of said array, said switching wheel including contact springs sequentially engageable with the contacts of said array when said wheel is rotated in said forward direction and a central contact engaging the central contact of said socket plate, the improvement comprising:
- said central contacts being in the form of spherical shell segments, one nested within the other.
