Abstract
A rubber structure contact connector includes a support upon which is placed an electrical contact. An insulating material, such as rubber, is applied over the contact and overlies the support and it has a portion which is formed as a raised dome-shaped resilient compressible portion or actuating key. On the interior of the dome-shaped, resilient compressible portion, there is a surface which has an oil-resistant layer thereon and a conductive portion which overlies the oil-resistant layer. The conductive portion is aligned over the electrical contact. In another embodiment, instead of the covering on the interior surface of the key which includes only an oil-resistant layer and an electrical conductive part, there is an electro-conductive part on the interior surface followed by an oil-resistant layer and another electrical conductive part.
