Abstract
A self-adjusting multicircuit brake switch is accomplished by employing a switch housing with an integral mounting means that is carried on a brake pedal actuation pin. The brake master cylinder push rod is also carried on the brake pedal actuation pin and directly actuates a plunger on the brake switch eliminating the need for adjustment. Multicircuit capability is provided by a plurality of blade switches that are actuated by the plunger with integral activation arms. The plunger's integral activation arms can be configured to: make or break electrical contacts when the plunger is depressed, mechanically break electrical contacts, sequence blade switch operation, and be micro-adjusted during production to compensate for component tolerance variations. Additionally, blade switches can be configured to provide contact wiping action.
