Abstract
The switch comprises a square, hollow housing. A base plate and a cover plate are snap fitted in stacked relationship. First and second elongated cavities in the base plate are respectively aligned with first and second cavities in the cover plate and within these aligned cavities are respectively located two elongated reed switches. A plunger is slidably carried by the housing and movable toward and away from the plates. The plunger carries two pairs of magnets respectively aligned with the reed switches. When the plunger is depressed, the magnets move into close proximity with the reed switches, closing them. A spring biases the plunger away from the reed switches, whereby the reed switches are normally open.
