Abstract:
A push-button switch comprising:a switch body;a main push button slidably disposed in said switch body between an initial position and a depressed position, with said main push button having a hole formed therein which extends in a direction that is oriented from the initial position toward the depressed position;a return spring for urging said main push button from the depressed position toward the initial position;a biasing spring in said hole;an opening in a side wall of said main push button, with said opening being in communication with a bottom of said hole;a ball at said opening;a concavity in a wall of said switch body that faces said main push button, wherein said concavity is to receive a part of said ball when said main push button is at the depressed position; andan auxiliary push button disposed at a top of said main push button, wherein said auxiliary push button is positioned against said biasing spring such that said biasing spring urges said auxiliary push button away from said main push button in a direction that is oriented from the depressed position toward the initial position, wherebywith said main push button in the depressed position, when said auxiliary push button is depressed against said biasing spring, said biasing spring forces said ball partly through said opening such that said ball is partly received within said concavity to temporarily fix said main push button at the depressed position.
