description

The innovation concerns an elastic clamp with contact for push-button switches, which terminal is obtained from a single piece of sheet metal Ut.

It is known to provide 1n pushbutton switches with elastic terminals which are connected to the contact blades of the tjKjitjiic mjHjit jihi <»» h; n odsr connected by soldering or can only be arranged in contact with them.

This brings with it a number of shortcomings Assembling with itself, since the ΤΉΙβ in correct mutual Position and must be kept. Furthermore, the multi-part design brings increased Staging and pre-assembly costs with it.

This creates another non-negligible problem caused that just for sheet metal parts arranged side by side in the mutual Contact points or at those with other elements the various components result in local changes in resistance due to inaccurate contact, which obviously brings with it an increased susceptibility to failure and the risk of overheating.

The task of the innovation is to create a component for push-button switches consisting of a terminal and a contact to realize that solves the problems mentioned and that extremely quickly and economically manufacturable, easy to install and safe to operate.
