ABSTRACT:
A switch, particularly one for indicating whether an automobile seat is occupied or unoccupied, comprises a switch housing with a spring contact secured at a base portion to respective side walls of the housing and extending inwardly from the respective side walls into biased contacting engagement. An actuating rod is guided for axial sliding movement through the housing and it includes a switching member having an upstanding portion of insulating material which extends between the spring contacts in a non-actuated position. The actuating rod is provided with a connection at its one end to a spring suspension of the seat so that the whole rod is shifted together with the switching member during the loading of a seat to move the insulating material away from its position between the spring contacts to permit the contacts to come together into conducting relationship.
