Contactor of the push button type and its use on key pads.

Abstract

Abstract The contactor is of the push button type with two operating positions, one termed rest, the other operating position. It comprises a key 1 carrying a contact pad 2 and connected to a base 3 by a straight hinge 9 over a portion of the junction, and by an elastic bellows 4 over the remainder of the junction. In the rest position, the key is kept inclined with respect to the base by the bellows. When a pressure is exerted on the key, the latter tilts about the axis of the hinge, the bellows folding up. The pad is then in perfect contact with the electrical elements 5 to be connected. When the pressure disappears, the bellows returns the key to its inclined rest position. Application to key pads of the flexible type.
