Abstract
A domed contact element 50 for a keypad assembly comprising a substrate (52) having the dome (54) formed therein, the dome being depressible towards the substrate so as to move from a first natural-bias position to a second position; a soldering site (62) on the substrate by which the contact element can be soldered to a circuit board; and a port (56) positioned between the dome (54) and the soldering site (62) to inhibit ingress of solder into the dome (54) during soldering.
