A door jamb switch has a first member adapted to be fixedly secured onto a door jamb of a motor vehicle, a first switch contact mounted on a plunger supported in the fixed first member for reciprocation along an axis between a first, door opened, position with the first switch contact engaging a second contact on the first member and a second, door closed, position with the switch contacts disengaging one another. At least one of two contacts is mounted resiliently in the switch, and the surface configurations of the two contacts can be made to interact with each other and with the resilient mounting so as to self-align the contacts with respect to one another upon interengagement therebetween. |

DETAILED DESCRIPTION In accordance with the present invention then, there is provided an improvement in electrical switches by which the foregoing contact alignment problem is minimized or overcome.
In the preferred embodiment the switch is of the type having a housing adapted to be fixedly secured onto a door jamb, a first electrical contact mounted on a plunger supported in the housing for reciprocation along an operating axis relative thereto and a second electrical contact which is supported on the housing to engage and disengage the first contact in response to displacement of the plunger in opposite directions between first and second actuated or operative positions by a door.
In accordance with the invention, one or both of the first and second contacts are resiliently mounted with respect to either the plunger or housing respectively, so that one or both can move or "float" and self-align with the other upon interengagement.
In accordance with one aspect of the invention, the resilient mounting allows axial, lateral and angular spring loaded contact movement relative to the operating axis of the plunger.
In accordance with another aspect of the invention, one or both of the contacts are mounted so as to provide rotational movement thereof with respect to the operating axis of the switch.
The "floating" contact assembly can comprise a contact block or terminal block onto which a contact is mounted.
The contact can consist of the contact itself, or can comprise a contact or electrically conductive contact surface mounted onto a holder, with the holder being resiliently mounted onto the block.
The "floating" electrical contact can be mounted in a cavity of the contact block, the cavity being cylindrical in cross-section with its axis being parallel to the operating axis of the switch.
A resilient washer is located in the bottom of the cavity.
The outward surface of the contact is contoured to have a radial dimension which increases along the operating axis of the switch in a direction toward the base of the cavity
