Abstract

An electrical switch (12) includes a pair of stamped switch contacts (20) opposed to each other at a gap (22). An insulative substrate (18) supports the contacts and includes a recess (34) below the contacts at said gap. The recess (34) is sufficiently large so that the switch contacts (20) extend into the recess and can flex relative to each other. A conductive actuator (38) is engageable with the switch contacts (20) at the gap (22) to close the switch, with either switch contact being flexible to ensure that the actuator engages both contacts.
