摘要： A modular contact switch adapted to be readily assembled from a plurality of contact modules is provided. Both active contact modules and passive contact modules comprise coupling features, including but not limited to, engagement tabs and mating surfaces, to enable a removable coupling of multiple active contact modules to form active contact assemblies and passive contact modules of a passive contact assembly. The active contact modules provide a spring-biased contact that responds to the position of passive contacts of the passive contact modules. As the active and passive contact modules come into abutment and urging engagement, an electrical connection is made between the corresponding contacts. The spring-bias of the active contacts ensures that the electrical contact is made regardless of variations in tolerances and position.

摘要： The present invention provides a door opening assist device comprising a spring-biased piston having a threaded bore mounted in a cylindrical housing by a threaded bolt. The piston retains a spring within the housing at a first end of the housing. The threaded bolt engages the piston from a second end of the housing. The piston is retained within the housing by the cooperative engagement between the spring urging the piston out of the first end and the head of the bolt in abutment with the second end. The door opening assist device is installed in a door frame of an automobile to push the door open a predetermined distance. The door opening assist device provides various mounting options. Upon closing the door, the door abuts and retracts the piston into the housing compressing the spring. Upon unlatching the door, the piston extends under spring bias in such a direction and with sufficient force to push the door to an open position a predetermined distance. The cooperative engagement between the bolt and the piston provides adjustment feature to tailor the opening characteristics of the door opening assist device to control the opening of the door.
