Abstract
Abstract Electric switch apparatus comprises a housing containing first and second pairs of contacts, the separate contacts of each pair being held normally open by resilient means locally deformable to allow separate engagement of either pair. A rocker member pivotably supported in the housing has a pair of legs, one extending toward one contact of each pair and effective to push that contact into engagement with the other contact of the pair against the bias of the resilient means as the rocker member is reciprocated to one of two extreme positions. The housing further contains a pair of spring detents, each comprising a metallic strip having one end fastened to the housing adjacent one of the legs and another end spaced from the housing for engagement with the adjacent leg as it moves away from its associated pair of contacts, to hold the rocker member in the position in which the other leg produces engagement of the other pair of contacts.

In switch apparatus of the type including first and second pairs of contacts in a housing, one contact of each pair being mounted on a sheet of flexible material separated from the other contacts of each pair by resilient means disposed therebetween, the resilient means being adapted to bias both pairs of contacts into disengagement but being locally deformable to allow separate engagement of either of said pairs of contacts; the improvement comprising, in combination: a rocker member pivotably supported in the housing and adapted for pivotal reciprocation by an external operator between first and second positions, the rocker member having a pair of legs, one of the legs being effective to engage the first pair of contacts and cause engagement thereof in the first position and to withdraw therefrom and allow disengagement thereof by the resilient means in the second position, the other leg being effective to engage the second pair of contacts and cause engagement thereof in the second position and withdraw therefrom and allow disengagement thereof by the resilient means in the first position; and a pair of spring detents in the housing, each spring detent comprising a resilient metallic strip having one end fastened to the housing and another end spaced from the housing for engagement with one of the rocker legs, one of the spring detents being adjacent each of the legs and effective, upon rotation of the rocker member to the position in which the adjacent leg is withdrawn from its associated set of contacts and the other leg is biasing the other set of contacts into engagment, to engage the adjacent leg and thus hold the rocker member in position and the other pair of contacts in engagement against the bias of the resilient means exerted on the other leg.
