<p>An electrical switch having redundant circuits, where the switch has a pivotable plunger (8) having an arcuate conductive bearing (12) and a contact tip (14). The plunger bearing (12) is electrically connected to the contact tip (14) and is supported on a conductive substrate (42). When the plunger (8) is pivoted from a first to a second position, the contact (14) tip closes a first circuit between the substrate and a first contact and closes a second, redundant, circuit between the substrate and a second contact.
