Abstract
Abstract A switching device is disclosed which includes a housing mounted on the accelerator rod or another part of an accelerator system of a motor vehicle. The housing encompasses switching elements which are operative in response to the change in direction of the pressure on the accelerator by the foot of the operator. The switching elements operate an indicator device at the rear of the vehicle to alert a driver in a trailing vehicle that the pressure on the accelerator pedal is either being advanced for greater speed, backed off for even speed or the foot entirely removed therefrom.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
179 words
An electrical switching device comprising: a housing carrying a contact, a movable rod extending through said housing and carrying a first set of contacts and having first protrusion thereon; a coil spring carried by said rod and extending between a side of said housing and said protrusion, a reactionary bar having a second protrusion thereon and carrying a second set of contacts and positioned for movement from a starting position with respect to said housing, a drag spring mounted in said housing and contacting said reactionary bar to provide firmness at contact points of said second set of contacts, a reflex lever pivotally mounted within said housing and extending between said first and second protrusions; said switching device being operative such that during switching operation the reactionary bar is moved from its starting position while the contacts are selectively opened and closed, and upon termination of the selective opening and closing of said contacts the reactionary bar is automatically returned to its starting position by the action of said spring releasing stored energy and causing pivoting of said lever.
Claim 2
Dependent Claim
179 words

Claim 3
Dependent Claim
14 words
An electrical switching device as defined in claim 1 wherein said housing is rectangular.
Claim 4
Dependent Claim
45 words
An electrical switching device as set forth in claim 1, wherein said housing is adapted for mounting on an accelerator rod and the contacts adapted to be electrically connected in a circuit to operate three-signal lamp warning device mounted at the rear of a vehicle.
