Abstract
A switching circuit is completed between electrical contacts by a flexible cap overlying the contact points. The cap is formed with cylindrical sidewalls and an upper end closure which has a plunger or piston-like portion extending therefrom towards the contact points. The dome section is arranged so as to arc from the cylindrical sidewalls in a direction away from the contact points so that depression of the dome will not effect collapsing of the cylindrical sidewalls for the entire extent of the contact establishing travel. The cap can deflect a metal dome to perform the contact establishment or can be composed of a resilient conductive material to directly establish electrical contact.
